Letting Go of 2˚ C, Letting Go of Race?: What does climate justice mean at 4˚ C?

Given the “existential threat to democratic governance” posed by a sober assessment of continued global climate warming, J.B. Ruhl and Robin Kundis Craig, in their provocative article 4˚C,  posit the need for a reframing of established approaches to climate adaptation.  Beyond the “Three Rs” of resist, resilience, and retreat, Ruhl & Craig suggest the urgent need for redesign, a process of radical transformation that may require “letting go” of closely held beliefs, expectations, and goals.  Facing a future where “human suffering is likely to increase dramatically,” the authors urge us to “ask uncomfortable questions” and consider even the most politically unpopular measures in order to preserve democracy through the cascade of change to come.  For Ruhl & Craig, necessary measures might include community relocation and “repurposing public lands for new human settlements.”  Could the same dramatic changes in a 4˚C world also require letting go of race and ethnicity as central constructs for pursuing climate justice?

For Ruhl & Craig, equity remains a fundamental principle for the redesign process.  They stipulate that any successful redesign must maintain “opportunities and support for individuals and communities that otherwise face significant risks of being ignored, overrun, forgotten, left behind, or otherwise further marginalized.”  In the United States, historically “marginalized” communities are often communities of color, including Black, Brown, Indigenous, and Asian-Pacific Islander communities.  Recognition of the disproportionate impacts of environmental pollution on communities of color gave rise to a movement for “environmental justice” that took hold more than thirty years ago and remains as strong as ever today. 

Unlike the Civil Rights Movement of the 1960s and the Environmental Movement of the 1970s, the movement for environmental justice has never produced national legislation like the Civil Rights Act of 1964 or the Clean Water Act of 1972.  Consequently, environmental justice has remained a largely grassroots movement, driven by community organizations and increasingly reflected in state legislation.

In the absence of national legislation, communities and scholars have long endeavored to define “environmental justice.”  According to the most common definition, maintained by the U.S. EPA and adopted by many states,

Environmental justice is the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income with respect to the development, implementation and enforcement of environmental laws, regulations and policies.

One key element of this definition, embraced almost universally by state law and policy, is the application to “all people.”  For the Bush/Cheney EPA, “all people” rejected a conception of environmental justice as a program of affirmative action with racial preferences.  Perhaps unwittingly, “all people” also opened the door to an inclusive conception of environmental justice as a program intended to protect all people—all of them—to include children, the elderly, the homeless, the undocumented, and LGBTQ communities. 

In the last two decades, the movement for environmental justice has inspired allied “justice” movements, such as “food justice,” “energy justice,” and “climate justice.”  As with environmental justice, climate justice has been the subject of numerous efforts to define it.   According to one simple definition, “[c]limate justice can be defined generally as addressing the disproportionate burden of climate change impacts on poor and marginalized communities.” Other scholars have submitted that “[a]s an extension of environmental justice, climate justice is understood to focus on ‘equal rights and opportunities [for] every individual to seek a high quality of life under the impacts of global climate change.’”

This inclusive conception of climate justice as applicable to “every individual” presents particular challenges for the 4˚C future.  How do we pursue a “high quality of life” and keep “every individual” safe from the impacts of a new climate regime that human civilization has never seen?  Climate models abound, but climbing past 2˚C and the tipping points of nonlinear change, how will we know what to look for, much less how to mitigate the worst impacts?

            While acknowledging the “no-analog future,” we can usefully examine experiences of the past and present to locate specific examples of disproportionate impacts from climate change, identify underlying causes for these impacts, and eliminate or mitigate such disparities in the future.  For example –

  • In 2005, Hurricane Katrina (and the anemic FEMA response) resulted in infamously disproportionate impacts among the Black population of New Orleans. Race discrimination operated systemically to place Black people in harm’s way and acted implicitly to frustrate recovery efforts. But in terms of keeping people safe, Black and white, more lives might have been saved immediately by concentrating rescue operations on elderly people, the population most likely to have impaired mobility.    
  • In 2017, in the wake of Hurricane Maria, studies indicated that the two strongest indicators for mortality among hurricane victims were diabetes and heart disease. While federal regulations often define Puerto Ricans as “minorities,” a focus on such “minority” status would not allow federal responders to direct resources toward those individuals in Puerto Rico most likely in need of immediate, lifesaving care after Hurricane Maria. 
  • In 2020, the COVID-19 pandemic resulted in particularly devastating impacts on Black, Brown, and Indigenous communities. The coronavirus itself did not discriminate by race, but researchers identified important conditions that made some racial and ethnic sub-populations more vulnerable than others.  Researchers from the Harvard School of Public Health, for example, found a strong correlation between COVID-19 death rates and air pollution, with poor air quality more likely found in urban environments with communities of color.  Another study by UCLA revealed that the Latino death rate from COVID in California was nearly six times higher than for Non-Hispanic whites, due to factors including lower salaries, less health insurance, larger households, and greater exposure to the public as “essential workers.” 
  • In late June 2021, the unprecedented heat wave experienced in the Pacific Northwest, with all-time high temperatures in British Columbia, Washington, and Oregon, resulted in strongly disparate impacts upon the elderly. According to one preliminary report, excessive heat—including a temperature of 116˚F on June 28—was directly responsible for 54 deaths in the Portland metro area.  Of these deaths, 81.5 percent were people ages 60 or older.  According to the report, “Lack of air conditioning was a key driver in mortality.  Whereas about 80 percent of people in the Portland area have some level of air conditioning in their homes …, none of those who died had central air, and only eight people had a portable air conditioning unit in their home.”

Significantly, and defying traditional notions about climate justice, the preliminary report found that recorded deaths from the extreme heat in Portland were 92 percent white as well as 63 percent male.  While these findings surely reflect the particular demographics of Portland, Oregon, they may also remind us that race and ethnicity will not always predict, and help us prevent, all the worst impacts from climate change, particularly in the 4˚C future (which in some ways is already here with 116˚F in Portland, Oregon). 

A different approach may be grounded in vulnerability theory, pioneered by scholars including Martha Albertson Fineman.  Vulnerability theory looks beyond suspect classes, such as race, to understand why certain groups or individuals may be more susceptible than others to particular impacts in certain circumstances.  Vulnerability theory has only recently received consideration in the context of environmental justice, and it remains ripe for exploration in the context of climate justice.  Through vulnerability theory, we may understand why white males experienced greater mortality from the 2021 heat wave in the Pacific Northwest or why Latinos may suffer most with increasing heat year after year in the Southwest.  Investigating climate justice through the lens of vulnerability theory leads necessarily to heavily contextual inquiries, eschewing generalizations and replacing suppositions with careful observations, analyses, and recommended actions. 

One timely example may be illustrative.  In certain regions, families commonly pass down real property from one generation to the next with minimal documentation of title.  In the Deep South, “heirs property” often reflects the Jim Crow area, when Black people were excluded from the legal system.  Today, this system of property ownership has left many homeowners (including many people of color) more vulnerable to disasters following climate-related events such as hurricanes.  After the devastation wrought by Hurricane Ida in August 2021, FEMA finally announced a change in agency policy, allowing disaster survivors alternate forms of documentation to establish home ownership.  This welcome change in FEMA policy addresses a vulnerability factor grounded in historic race discrimination but persisting in new needs to prove property ownership.

So will keeping people safe in the 4˚C world require letting go of race?  Given our history in the United States, including the racist histories we have only begun to acknowledge, the answer must be “no,” we cannot let go of race.  To survive and thrive in the “no-analog future” will take everything we’ve got.  We will need artists, economists, engineers, lawyers, historians, and health professionals, as well as governance on all levels, the private sector, and community organizations.  No one person needs to do it all.  But we will still need some people to keep an eye on race to continue remedying mistakes of the past and help us avoid mistakes in our future.   As Ruhl & Craig observe in conclusion, “We can do better to prepare the nation for the path to 4˚C.”  Preparing for that future may require letting go of some old notions and modes of inquiry, but may also require holding onto some lessons from the past.

Contemplating Equity from the Deck of the Titanic: A Metaphoric Meditation for a 4°C World

Indulge an extended metaphor.

The deck chairs on the Titanic are not arranged so that all passengers have fair access to them. For that matter, all the ship’s amenities are inequitably distributed, from food to medical care to cabin space. Many of the passengers enjoying the benefits of first class can afford to be there only because their parents, grandparents, or great-grandparents seized and exploited the wealth and labor of colonized people in the Global South, establishing the white privilege from which these passengers have benefitted their entire lives. In contrast, many of the passengers in steerage (third class) don’t really deserve to be there, either, having been trapped by an exploitative capitalistic system of labor in the lower classes. But they still benefit from white privilege, as evidenced by the almost complete lack of non-white passengers on this oh-so-prestigious crossing. Nevertheless, their safety is far less protected, and if someone below decks dies in a fight belowdecks, it is questionable whether anyone will do anything about it. The environment that these people must live in is also far less pleasant, although, admittedly, often better than what they were used to at home—close quarters, poor air circulation, shared meals and sanitation facilities, and fellow travelers who are often sick, both from seasickness and shared contagions.

No doubt about it: the Titanic needs an equity overhaul.

HOWEVER:

The ship is on a collision course with an iceberg, and there aren’t enough lifeboats for everyone.

So, pop quiz: Do you put energy into rearranging the deck chairs (and other amenities)? Or do you try to get a few more lifeboats built before the ship goes down?

Accepting the real possibility of a 4°C increase in global average temperature by the end of this century or very soon thereafter (and maybe earlier) complicates how one thinks about every aspect of human society, and that includes equity. At the very least, as the Titanic metaphor suggests, a 4°C world raises the possibility that the actions we should be taking now to promote survival equity (e.g., build more lifeboats) are not the same as the actions we want to take now to promote day-to-day equity (e.g., ensure more equitable access to societal amenities and, perhaps, redress past exploitations). However, there is also a possibility—one that J.B. Ruhl and I raise in our article 4°C—that this radically warmer world is a disruptive opportunity, that the dislocations and rearrangements it demands in response to its impacts are what will allow the full range of social transformations needed to greatly improve equitable distribution of amenities and access to opportunity. In other words, there’s the distinct possibility that a radical survival-based adaptation modality (what we call redesign adaptation) is exactly what will finally allow for radical progress in day-to-day equity, somewhat analogous to how the social transformations of World War II helped to pave the way to the Civil Rights movement.

But, of course, there’s an added complication that the Titanic metaphor elides through the immediacy of the oncoming iceberg catastrophe: Improving day-to-day equity now—at least in some respects—might also promote survival equity later. That proposition seems intuitively obvious. Indeed, it helps hone the narrative edge of one of the opening scenes in Kim Stanley Robinson’s CliFi novel Ministry for the Future: During a disastrous extreme heat wave in India, a lone American aid worker survives being parboiled in the lake that everyone has entered in an attempt to keep (relatively) cooler. As the reader learns before this gruesome scene, the American has been keeping the limited supply of cold, clean, fresh water available at his office to himself, the last of which he takes with him to the lake. As another character suggests later, this relatively small advantage in hydration, coupled with a lifetime of being well-fed and medically cared for in the United States, might be the only explanation of why he survived and the local Indians did not.

Which raises the last and most difficult part of contemplating equity in connection with a future that is 4°C warmer than the present: People are going to die. How to keep that reality from devolving into “them versus us” politics is a serious governance challenge for a 4°C future. On the real Titantic, after all, status was a major determinant of whether a person survived: Approximately 76% of both the crew and third-class passengers perished, compared to 68% of the total number of people on board, 58% of the second-class passengers, and 39% of the first-class passengers. First-class women and children passengers, in contrast, survived at a rate of about 97%.

Given that the risk of death increases dramatically as the global average temperature increases, what does 4°C survival equity actually mean? To get the discussion going, I posit that 4°C equity means that any individual’s chances of surviving and thriving are not statistically correlated with the person’s race, class, socially assigned gender-based status, or relationship to colonialism. Instead, the 4°C world will be a lot more equitable if a person’s chances of survival are, on the whole, either: (1) relatively random from a social policy perspective (e.g., genetics, getting caught in freak disasters); (2) based on characteristics that we all will share (e.g., vulnerabilities associated with aging or special protections accorded children); or (3) the result of individual choice (e.g., refusing to move out of harm’s way when there is real opportunity and ability to do so).

Let the debate commence. But where the heck did that deck chair go?

The Costs of Political Polarization and Gridlock

Although some Republican officials have signaled a willingness to work on mitigation and adaptation policies, political promises to address climate change still largely come from only one party: the Democrats. In fact, according to the Center for American Progress, 139 members of the 117th Congress reject climate science and the reality of a warming world; all 139 are Republicans. State governors follow a similar pattern with several Republican governors vowing to fight the Biden Administration’s efforts to lower emissions before specific policy proposals even surface.

Climate change is not the only problem that is complicated by the political polarization that pervades our political and social institutions, but it is likely the problem that will cost future generations the most. The most recent IPCC report is clear: we can avoid the worst-case scenarios for warming only if we act today. As I write this, Democratic members of Congress cannot even reach agreement among themselves about how much to spend on pressing problems including climate change. The political gridlock shows no signs of abating. It is the source of the anger and anxiety that Jessie Owley describes in her blog post.

Can we assess the costs of this political failure to address climate change? Newer climate models suggest that costs are high. These models, which are considered in the latest IPCC assessment, use a set of five narratives about the future of global socioeconomic development to forecast different warming scenarios. Created by an international team of experts, these five “shared socioeconomic pathways” offer different visions of the future based on the influence of various socioeconomic factors.

The “regional rivalry” narrative (SSP 3) is the worst-case scenario because it presents the steepest challenges to both mitigation and adaptation. This is a world defined by rising nationalism and decreasing global cooperation. It is a 4°C world unable to adapt because democratic institutions fail, and cooperation is impossible. Although this development narrative contemplates rivalry at a global scale, political gridlock and polarization at the domestic level only make the international trends in that direction more likely—especially when these divisions undermine climate policies in wealthy nations like the United States.

In their blog post, J.B. Ruhl and Jim Salzman modify the Rawlsian “veil of ignorance” thought experiment to give the lawmaker knowledge that the world will warm to 4oC over the next 200 years. Their post made me wonder what effect this knowledge would have on our foundational constitutional commitments. Understanding that society will have to adapt to a warming world, we would no doubt want to make possible the kind of anticipatory and adaptive governance that they envision. But could we accomplish this without throwing out much of our constitutional structure?

Would we make different choices? For example, our constitutional structure is designed to make laws difficult to enact and change. Would we design our political institutions differently so that it is easier to change the status quo? Would we give states less control over national elections? Would we preclude political gerrymandering of election districts? And would we be willing to commit ourselves to limitations on speech that current First Amendment doctrine does not? For example, would we permit the regulation of false and misleading speech when it undermines the ability of others to speak? Would we commit ourselves to meaningful regulation of money in politics?

These are big questions that would ignite contentious debates today. I do not mean to suggest answers, but only to highlight some of the constitutional commitments that enable or at least aggravate political polarization and ideological division—and to acknowledge that these commitments are deeply entrenched in our constitutional culture. Ideas and norms grounded in the separation of powers, federalism, and free speech are not easily challenged.

So, if we are to break the gridlock on climate change, we will need climate change to break out of its partisan prison. Work in cultural cognition studies shows that people will hold onto beliefs even when credible evidence proves them wrong when those beliefs are closely tied to their social and cultural identities. If acknowledging the scientific consensus regarding human-caused climate change requires breaking from your group’s belief system, then it is less costly to you to continue denying it. We are seeing this dynamic play out with the anti-vaccination movement during the Covid-19 pandemic as some anti-vaccine groups invent new narratives to justify their continued rejection of vaccine safety and efficacy.

There are signs that the cost-benefit calculus is shifting for some Republicans in Congress who now acknowledge the threat that climate change poses. We need more of these voices to speak now and speak loudly. There was a moment about thirty years ago when climate change had more bipartisan support. It must happen again. Although we may feel today that we have little in common with people on the other side of the political divide, we will share in whatever future we make for ourselves now. The costs of continued gridlock are simply too great to give up on bridging the divide.

Rawls@4°C

The “veil of ignorance” thought experiment devised by the philosopher John Rawls has long haunted law school seminar rooms and lecture halls. And for good reason. In his ambitious 1971 book, A Theory of Justice, Rawls offered a way to determine just principles of law from a purely selfish perspective. What would he have to say to us in the era of climate change?

Imagine, he says, that you are the lawgiver operating today. If acting purely from self-interest, one would expect you to establish laws that favor you and your friends/family/colleagues. No surprise that we see this around us every day. Rawls’s thought experiment, though, changes the game. You are still the lawgiver, but you are now operating behind a veil of ignorance. Once you have established the laws and removed the veil, you will then learn whether you are rich or poor, white or black, young or old, a citzen of France or Bangladesh, etc. 

Rawls argues that, operating in ignorance of your identity, you will choose principles that ensure the fair and equitable allocation of rights, duties, and opportunities among everyone in the society. Since you don’t know who you will be, best to provide for every possibility and favor people equally. 

Professor Edith Brown Weiss took Rawls’ veil of ignorance one step further, asking what it means for sustainable development. In her version, you not only do not know who you are, you also do not know when in the future you will live. It could be in the present, or three or six generations hence. If you were negotiating under this veil of ignorance, what types of rules would you want to impose? 

In this framing, our obligations to future generations become immediate. Professor Weiss proposes a principle of “intergenerational equity” that would seek to ensure future people will “inherit the Earth in as good a condition as did their ancestors and with at least comparable access to its resources.” Since you don’t know who you will be, best to provide for every possibility and favor people equally, now and in the future.

Let’s play this mind game a little further. Imagine, if you will, that you are still the ruler operating behind a veil of ignorance—you do not know who you will be or when in the future you will be. But, and here’s the twist, you do know that the world is unavoidably on a path to 4oC over the next 200 years. You could live anywhere on that path—2oC? 3oC? 4oC?—you don’t know. With this knowledge, what laws would you establish today to best ensure a fair and equitable society over the next 200 years of climate change? And how would these be different than Professor Weiss’s framing for sustainable development?

The climate change veil of ignorance changes the game in two important respects. First, although scientists can develop rough scenarios of what the world experiences along the climate change path, significant uncertainty remains, especially at local scales. You’ll have to design rules for the future now without a firm grasp of what the future looks like for many people. Second, it is more likely than not that climate conditions for many people will deteriorate, making it nearly impossible to set up rules in the present that will ensure future generations inherit an earth in as good a shape as prior generations experienced. You can’t stop sea-level or temperatures from rising,so you can’t satisfy the goal of the Weiss thought experiment.

These constraints change the kind of thinking that Rawls and Weiss expected of their rulemaker in three ways. First, given the 200 years of vastly changing conditions that lie ahead, the rules you design today must be rapidly adaptable as predicted changes evolve and unforeseen changes arise. If you wind up living in the 3oC world, you likely would not want to be bound by rules that applied in the 1.5oC world. So you must design an adaptive governance regime, not a fixed set of rules with the hope of locking in socially just conditions in the present and going forward.

Second, you'll need to anticipate tipping points and nonlinear change trajectories without knowing when they will be triggered or what the other side looks like. When will massive domestic migration start, and where do the migrants go? What if you are one of those migrants? Your adaptive governance regime will need to include a substantial planning and monitoring component using updated scenario projections—what social scientists refer to as anticipatory governance.

Finally, in addition to the resource consumption tradeoff dilemmas that sit at the heart of Weiss’s exercise, your rules will also require an ongoing process for determining how much to invest at any given time in protective adaptation measures for future generations. What if you live in the future as a resident of a city that did not build adequate flood control infrastructure or heat wave relief opportunities? But how much should a previous generation have invested? You can't possibly make all those decisions in the present—there’s too much uncertainty. The adaptive-anticipatory governance regime you design today thus must focus not only on sustainable resource conservation but also on capacity, ensuring continuous decision making for provision of physical and social adaptation infrastructure.

In summary, the climate change veil of ignorance will demand a much more fluid governance process, one that continually anticipates unforeseeable change, nimbly adapts the rules, and manages over long time frames for adaptation measures that equitably protect future generations. The fairness question will not be how to ensure future generations enjoy the same quality of life, but how to protect those groups (including possibly you) that will be much worse off.

Harnessing Eco-Anxiety and Triaging for the Future

Our children are scared and anxious. Our climate scientists are facing unprecedented levels of stress and depression. The future appears a dark and scary place. Sometimes, it seems like the only sensible engaged response is to pour all energy and attention into climate change mitigation. Climate change impacts are already severe, and there seems no realistic scenario where things aren’t worsening. Through the Paris Agreement, the nations of the world agreed to hold global warming to 2˚C above pre-industrial levels while (1) acknowledging that the real goal should be 1.5˚C and (2) failing to set in motion any measures that would realistically achieve the 2˚ goal. It is understandable that many of us are feeling stressed and depressed.

Some activists argue that we should embrace this eco-anxiety and use it to motivate action. If nothing else has spurred us to act, maybe fear will be the final push we need.

The challenge is how to harness our eco-anxiety into a fight for climate mitigation without leaving behind our other environmental or societal aspirations. The time has come for us to make the hard choices for what we want our world to be. Our economies were built on the idea that we can have it all. We throw the word “sustainability” around, suggesting that there is some magic sweet spot we can find where we meet our economic, environmental, and social goals simultaneously. But it hasn’t worked. The economic drivers remain dominant while environmental and social goals seem increasingly unattainable. As we look out at the 4˚C (and rising) world we have created, it seems time to acknowledge that we just can’t have nice things anymore.

Now comes the winter of our hard decisions. What are we willing to sacrifice? Should we fight to protect an endangered desert tortoise if it will hamper our development of renewable energy facilities? Are we willing to rely on nuclear power in exchange for getting rid of our coal-burning power plants? The questions get even trickier when we add climate change adaptation choices. Are we willing to put our parks and special places to more active use as climate migration forces people and facilities to relocate?

Environmentalists are now so worried about climate change that our eco-anxiety is making us willing to compromise and sacrifice our other environmental goals. Yet, are these really the places to push for change? We should all make changes in our daily lives. We should drive less and stop eating beef. We should reduce the single-use plastics in our lives and question our consumption habits. But environmentalists being better environmentalists is not moving any needle. Compromising conservation goals to combat climate change might be needed, but only after we have tackled the bigger structural problems in our economy.

International climate law is guided by the principle of common but differentiated responsibilities (CBDR). Could we take that same principle and think about it not across countries but across interest areas? Why isn’t it the big economic players that should change? Environmentalists may find themselves willing to sacrifice protected lands and endangered species, but should they? Doing so is at heart an acknowledgement that we are going to continue propping up industries that mismanage and burn fossil fuels.

What does this lead to? Combining our eco-anxiety with righteous anger. So we are angry and anxious and the only people who are willing to act aren’t the ones we *need* to act.

And now I have written myself into a corner. I have no solution, especially not one that can be expounded on in a short essay. As professors of environmental and climate change law, we all use techniques in the classroom to prevent our students from becoming too depressed. I show how, despite the challenges that remain, our air is cleaner since the passage of the Clean Air Act. Many of our waterways are in better shape even with the economic and population growth we have experienced. I point to movements in big cities in the United States and Europe to reduce cars and encourage electric vehicles. We have better control of pesticides and disposal of toxics. But frankly, I am at a loss when trying to do a climate change pep talk. Our political and economic leaders continue to deny, ignore, and obfuscate.

Decades of knowledge about the problem has not resulted in significant progress. Furthermore, the COVID pandemic illustrates that we (as a species and definitely we as Americans) are willing to let millions of people die even when science is clear and solutions are not that onerous. Climate change solutions won’t be as easy as getting a vaccine or wearing a mask. It won’t be simply flying less and carrying around a reusable bag.

The only glimmer of hope in the climate change debate is that the number of people paying attention is growing. The number of people morphing their eco-anxiety into righteous anger is increasing. Next time my students look to me for hope, I will have none to offer. But maybe anger is what they need instead.

More Better Information as 4°C Preparedness: Ecosystem Benefit Flows and Community Engagement

From an ecosystem services perspective, access to nature—and the benefits that come from functioning ecosystems—is poorly distributed across class, race, gender and throughout communities.  We might explain the divide by comparing ecosystem services demand between rural and denser population areas, or the manner in which our cities and towns have become socio-ecological traps, where perceived need continues to drive reallocation of water into cities in a way that reflects the disproportionate appropriation of ecosystems by cities. We might also recognize that occupation of upstream areas, particularly rural and suburban areas outside of cities and towns, places an enormous amount of power in the hands of those who manage, but may not directly benefit from, ecosystem service flows. 

Given such allocation challenges of ecosystem services, resource decisionmaking is often disconnected from the communities and individuals that would benefit from ecosystem services, and this divide is pervasive at the urban/rural interface.  Moreover, the divide will become increasingly acute as climate change continues to drive more intense storms, droughts, wildfires and disease, as well as rising temperatures and continuation of the human and ecosystem migration.

How do we bridge the gap?  One promising avenue involves mapping of ecosystem service benefit flows between and among geographically distinct communities.  Ecosystem services—a form of wealth—concern the benefits that humans derive from functioning ecosystems and includes provisioning services (e.g., goods), regulating services (e.g., nutrient regulation), supporting services (e.g., structural and other mechanisms), and cultural services (e.g., spiritual, recreational, and aesthetic)  Ecosystem services research illustrates the enormous costs of losing functioning ecosystem services (regulating, supporting and cultural, but also tradeoffs and temporal loss of provisioning services such as forest harvest or conversion at the expense of habitat productivity or flood and erosion control). 

Mapping the flows of ecosystem services helps to identify life-supporting benefits (to humans) from functioning ecosystem services and, in some ways more importantly, helps to identify the beneficiaries of those services, a neat trick that will also inform the distribution of ecosystem benefits.  Consequently, although the ecosystem services approach may not solve all of our equity problems, the information generated through benefit-flows mapping will facilitate more effective and equitable resource management planning beyond local borders in the following ways.

First, mapping ecosystem benefit flows begins with an inventory of the ecosystem services at hand, their supply and demand.  Understanding ecosystem services is a crucial step away from the resourcification of ecosystems, the process of conceptually transforming ecosystems from the processes they engage in to a pile of commodifiable resources for the market. The spatially explicit information generated in benefit-flows mapping “provides baseline data to measure new future gains or losses for policy impact assessment,” engendering more effective planning decisions.  Moreover, mapping flows will provide better information for understanding shifting risk factors resulting from ecosystem migration and for targeting areas where fruitful ecosystem investments could accommodate human migration.      

Second, mapping these flows helps to foster understanding of the relationships between different stakeholders and the ecosystem processes that provide benefits: “Understanding of ES flows is essential for understanding ES demand as they allow people to actually benefit from a good or service.” In many cases, mapping illustrates the ways multifunctional landscapes provide cascading services, suggesting that attention should be given to sub-units and specific benefit demands that might be overlooked (and thus ignored) from generalizations about ecosystem-wide services.  Benefit-flow mapping also helps to “identify which regions are critical to maintaining the supply and flow of benefits for specific beneficiary groups.”

Third, mapping benefit flows will provide a better understanding of the power relationships between ecosystem service beneficiaries, with recognition that “those stakeholders able to manage . . .  keystone ecological properties and ecosystem services can affect the well-being of other stakeholder groups by determining the ecosystem’s capacity to provide services and/or by controlling them.”   

Finally, if we want all communities to improve resiliency, engage in adaptive measures, and otherwise be prepared for climate change, we have to think in terms of climate justice.  Benefit-flows mapping will provide an accessible depiction of the ways that geographically distinct communities are related and connected.  It will assist as stakeholders engage in communicating needs and priorities among ecosystem benefits and empower more specific and effective communication within and among power relationships, ensuring a more equitable allocation of resources to where they are needed.    

Mapping benefit flows is an act of community empowerment. The process will activate perspectives on accountability and collaboration in the preparedness process. It provides granular-level information about the different dependencies and power structures among forest, watershed, agricultural and groundwater-dependent communities.  And, in the end, it will give us all something to talk about.

Climate Change Lessons from a Disney Princess

It may seem an unlikely connection, but while reading Robin Kundis Craig and J.B. Ruhl’s excellent (if depressing!) paper 4° Celsius, I found myself thinking about the Disney movie Frozen II. Frozen II presents a parable about climate change through the story of a young queen named Elsa leading her country during a period of rapid change in the natural environment. Amidst rapid changes and uncertain circumstances, Elsa’s governance approach becomes “do the next right thing.” Like the characters in the film, we find ourselves in a time of deep unknowns, where there are no predictable or “correct” answers. Conditions are changing and evolving more quickly than Congress or agencies can regulate. Forecasting is complicated; creating political will is near-impossible. Yet, the effects of climate change necessitate ex post responses. Responding to droughts, wildfires, hurricanes, and floods inherently relies on small groups of people working together in localized ways. Fortunately, the tool of stakeholder collaborations can fill this void between the lack of agency knowledge and preparation and the urgent local demands of disaster reponse, providing an important, yet overlooked, piece to effective climate change response.

Stakeholder collaborations are small groups of people working cooperatively in an ongoing way to guide agency land and resource management decisions. In 2017, the Administrative Conference of the United States (ACUS) hired me as an academic consultant to create a longitudinal overview of the use of collaborations by thirteen federal land and resource management agencies. The resulting report showed that thousands of stakeholder collaborations exist, a level of governance that merges localized considerations with federal agency action which is largely unexplored in administrative law scholarship. Subsequent work explored the doctrinal questions surrounding collaboration and ways that collaborations can be used to improve representation in federal agency decision-making, highlighting the benefits and downsides of this tool.

Most vitally to considering Craig and Ruhl’s thought-provoking paper, the ACUS research revealed that much agency action in climate change response and mitigation is happening through federal land and management agencies engaging in collaboration. This is good news. Agencies are experts in using collaborations; courts are good at assessing them. We have a hidden tool in our belt, one developed before it was so crucially needed.

In the future, I plan to write a paper outlining how stakeholder collaborations are vital to the kind of adaptive response for which Robin and JB advocate. For now, I sketch three brief lessons drawn from years of studying stakeholder collaborations.

First, it is time to let go of baselines and instead embrace values of ecological responsibility. In a changing climate, we will expend ever-increasing amounts of resources if we work towards the goal of preserving a rapidly shifting natural world. Our focus should shift from preservation to building and maintaining rich natural environments—albeit with the understanding that they may look different than the environments of the past. It may help to look to traditional ecological knowledge embedded in Indigenous conceptions of nature (which are many and varied) to understand the earth as a living thing—forever changing—while also understanding that our obligations to act responsibly toward the natural world are fixed.

Second, the present degree of polarization must end—our survival depends on it. As the parents sitting in the theater know, there is little to be gained from fights over who started a conflict or who did what to whom. Instead, maintaining functioning and healthy families requires adopting skills of healthy communication in which all participants can respectfully express their opinions and reach negotiated outcomes. National politics are not so different. Stakeholder collaborations force those with strongly held but conflicting objectives to negotiate, shifting from he-said, she-said to an adult conversation—kind, firm, fair, compassionate, and willing to find a middle ground.

Third, we must be bold and welcoming of new and unconventional ideas, which means pursuing and valuing diverse ideas and perspectives. We need new approaches. I believe that marginalized members of society—those most absent from academic discourse and positions of federal policymaking—hold the insights that are key to our collective survival. For example, the use of traditional ecological knowledge to restore fire to the forested Northern California landscape or manage caribou herds in Alaska combines Indigenous land management practices with agency action. Stakeholder collaborations are a way to radically democratize environmental decision-making and incorporate more diverse perspectives, which are sorely needed.

Frozen II taught millions of American children a lesson, which adults need to learn too. In problems, rest opportunities. Climate change is an invitation to redefine and better articulate our values—those towards the environment, one another, and marginalized communities. Values guide actions amidst rapidly changing circumstances and deep uncertainty. Stakeholder collaborations are a forum for doing so while producing desperately needed adaptive governance. They are the way we can continue to—one step ahead of another—do the next right thing.

The 4° City

Just as rising global temperatures will accelerate change in ecological systems, a 4° Celsius world will catalyze social changes in the United States. In some parts of the country, these changes will include greater need for rapid emergency responses, heavier reliance on healthcare systems, and obsolescence and emergence of industries. In other parts, they will include the need to accommodate population influxes and a greater draw on social services. Though it is impossible to generalize regarding what life in four-degree cities will be like, it is clear that such a world will require different local responses, of different magnitudes, than we see currently. Some of the questions that this level of warming will raise are: What must a city give up in a world of four degrees warming? What should it be unwilling to lose? And how might it need to transform?

Many cities will lose both land and people in a four-degree world. Contemplating that first loss, land, is likely to feel sacrilegious to many cities. There are currently few incentives, and many disincentives, for a city to shrink its square footage. Property taxes are generally the primary funding mechanisms available to local governments. That tax base, tied so explicitly to land and what is on it, means that a loss of property equals a loss of revenue. But a four-degree world will render large parts of many cities unlivable and will require dramatic reconfigurations of others. Many cities will experience the loss of land beset by flooding, fire, drought, or other destructive forces. Even if these disasters do not result in the total destruction of the land, they may well alter its usability and the buildings—and taxpayers—upon it.

Those realities mean that many cities will lose some of their property tax base. It also means that cities will be forced to choose what to protect and what to abandon. Historic sites, cultural objects, and landmarks may need to be abandoned in favor of investing resources to protect people who used to live in the city and those who may remain. Because along with the land and property, population loss will be an inevitable part of a four-degree future in some places. There is no amount of adaptation that will be sufficient to keep current population levels in place in many cities, particularly those in coastal areas vulnerable to sea-level rise or located in the West, where water resources will be increasingly scarce and temperatures increasingly ill-suited for human habitation. Thus, cities will have to contend with the loss of people, with successful out-migration as a best-case scenario, and loss of life to flooding, heat, and fire a real prospect as well.

Those losses are enormous. They will feel enormous. But to confront them in a clear-eyed way, cities will need to face the question of what they can provide in a four-degree future and what they must retain so they can fulfill their new roles. Cities will still exist, likely in even larger form as climate change is expected to fuel massive urbanization. And the COVID-19 pandemic has illuminated the vital role of cities as places where people gather and seek aid. This has long been the role of cities, and they will continue as important intersections of public and private space. Cities can and should also retain the ability to be a locus for expression of local opinions, needs, and culture. A four-degree world will impact communities in distinct ways. 

As the level of government closest to the ground, cities can play a role in responding to shifting and varied needs. To fulfill those roles, however, however, cities must retain local authority. For example, at different points during the COVID-19 pandemic, local entities such as cities and school districts have attempted to combat local spread by implementing mask mandates and other public health measures. In some cases, state legislatures have reacted by prohibiting local governments from taking such actions. This dynamic strips away an important layer of crisis responsiveness, and makes very difficult for local entities to respond to the health and safety needs of their citizens and constituents.

There will be times when local authority is exercised in ways that run counter to the best science and policy on climate change. For example, local governments in many states have created barriers to renewable energy facilities being sited within their boundaries. Local governments have economic and political incentives to promote development in coastal areas vulnerable to sea level rise and flooding. And parochial actions at the local level have long been used to limit available housing stock, as well as to drive gentrification; it would not be surprising to see similar trends in climate destination cities when larger population shifts start occurring. A call for protecting the capacity for local action in reponse to climate change does not and cannot guarantee the shape of those actions. But even with some inevitably undesirable local actions, experience has shown that cities are often on the front lines of climate planning and, depending on the politics of the moment, may be the only entity in the federal system willing to take action. Beyond that, they are the entities most likely to know and understand the needs of their citizens in a rapidly changing environment, and they are going to need to respond to large swings in population, public health needs, natural disasters, and more. The federal government and the states must play an outsized role in making the regulatory and structural changes a four-degree future will require, and can exercise their authority to set regulatory floors for local government climate response. It would be a mistake, however,to fully strip authority from local governments to act.

So what needs to change to allow four-degree cities to fill the roles required of them? There are of course as many answers as there are local governments. All, however, are likely to center on some version of flexibility. Every city will need a greater ability—and, perhaps, a new willingness—to understand and interpret climate data and to use that data in planning for the future. In doing that planning, both physical and policy agility will be hugely important. Physically, cities must recognize when they are entering infrastructure time horizons that no longer make sense; having the foresight to avoid committing funds and locking in obsolete physical patterns (such as water lines in flood-prone areas, new development unsupported by available water resources, massive infrastructure aimed at serving shrinking populations, and others) will be crucial for city survival. Cities must also be willing to reimagine planning documents to account for new physical realities and changing demographics.

On the policy side, cities must be nimble enough to adjust to the needs of their citizens and willing to engage with those needs without being too wedded to the past. Depending on the city, that may mean managing water rationing, adapting the housing supply, making decisions about whether or not to rebuild in areas impacted by natural disaster, providing health and disaster response services, joining forces with other cities for service provision, and on and on. All of that will require the four-degree city to have greater flexibility in financing and in collaborating with other jurisdictions. As described above, local governments cannot afford to lose this authority over climate responsiveness, and many may in fact need to acquire that authority in the first instance. Broadly speaking, this flexibility and autonomy are something that can only be—and, where it is lacking, should be—conveyed by the state. The prospect of a four-degree future, and the limited capacities of all levels of government, should serve as an impetus for a more expansive idea of local authority. States could ensure local flexibility by, for example, reforming available local revenue sources, allowing for and encouraging regional planning around climate impacts, and at a very broad level, putting in place forms of home rule authority that presume local ability to act and move away from deregulatory preemption. Cities in a four-degree world will have much to contend with; one thing they should not have to worry about is the authority to act.

The four-degree city is likely to be similar in mission to current cities, but will perhaps have a very different footprint and make-up. Current local government structures, including financing mechanisms, policy incentives, limited authority, and entrenched commitments, make it extremely difficult to accommodate this coming reality. Now is the time for cities, states, and the federal government to ensure that cities that will be impacted by climate change (read: all of them) have the authority and flexibility they need to prepare for a four-degree future.

The Mutable Boundaries of a Worst-Case Climate World

Climate change disrupts the boundaries that demarcate human existence.

Boundaries are an essential tool in contemporary human life. They produce and entrench identity. They ground governance systems. They determine who can come, who must go, and what the terms for living among others will be.

Law codifies and fixes boundaries. It defines political and property boundaries, and even seeks to delineate the boundaries of ecological systems. These boundaries, too often, are politically and environmentally arbitrary. They divide and reconstruct communities; they fragment ecosystems.

Questions of boundaries consume legal scholars—how they are constructed, how they operate, how they evolve. For environmental lawyers, these conversations frequently advance ecologically oriented thinking and the benefits of acknowledging functional, rather than geographical boundaries of ecological systems and ecosystem services. Increasingly, they also center consideration of planetary boundaries that “define the safe operating space for humanity with respect to the Earth system.”

In a territorialized world where boundaries are the foundation of the rule of law, and indeed the body politic itself, shifting boundaries are a conundrum. They pose existential challenges to systems of law that thrive on and, too often, assume stability. Stasis is law’s comfort zone. Climate change shatters assumptions of stasis. It doesn’t just force us to rethink boundaries; it moves the boundaries right under our feet.

In a worst-case climate world, climate change will redraw our maps, rewire our minds, and revolutionize our politics. For the sake of simplicity in this short blog, we can imagine key shifts along the axis of the physical, psychological, and the political.

First, the physical. Climate change is altering our landscapes. Globally, the tropics and the Sahara are expanding.  In the United States, flood zones fluctuate, the 100th Meridian line shifts east, and plant hardiness zones push farther north.  But it’s not just climate zones and ecosystem boundaries that are changing. Glacial zone retreat in the Alps blurs the border lines between Italy and Switzerland. Equally, Arctic coastal states scramble to expand their outer continental shelf boundaries as sea ice disappears and new opportunities appear for territorial expansion.  

Second, the psychological. As physical boundaries shift so too does our sense of place, stability, and identity. As our landscapes change, we are forced to rethink who we are, where we belong, and what we are capable of absorbing. The physical health effects of climate change are too many to mention. But the indirect psychological effects of both slow and sudden onset disasters—climate anxiety, ecoguilt, and the psychological effects of displacement and diaspora—are likewise daunting. In a worst-case climate world, our sense of self, security, and well-being teeters on a precipice.

Third, the political. Even as landscapes and our sense of place and identity shift, we imagine our political systems largely functioning in stand-still mode on a stand-still planet. In today’s almost, but not yet worst-case climate world, mainstream politicians continue to advance stasis-dependent frameworks—property, gray infrastructure, and resource extraction—and stasis-driven responses to climate change—carbon taxes, cap-and-trade regimes, bridge fuels, and technological fixes. Yet different visions for the role of law are emerging around the peripheries of mainstream politics. These visions perceive the shifting ground of climate change and seek to harness law as a tool not for sustaining the norm, but instead for engaging (rather than ignoring) inevitable disruption and creating opportunities to reimagine the world unfettered by fixed boundaries.

Moreover, across the domains of the physical, psychological, and political, law frequently employs concepts of boundaries to classify humans—to determine who is worthy of inclusion and who will be excluded. These forms of conceptual boundaries are deeply embedded in our systems of law and tend to reinforce persistent patterns of inequality. Unaddressed conceptual boundaries intensify historical patterns of othering and exclusion along lines of race, gender, religion, sexuality, country of origin, and socio-economic status. Moreover, conceptual boundaries operate particularly perniciously for those who straddle categories of historical exclusion. Absent efforts to the contrary, unfettered climate change threatens to further deepen the subjugating tendencies of law’s conceptual boundaries.

In a worst-case climate world, we will be confronted with levels of destabilization that challenge us to rethink what is possible at every level of governance. In this climate-destabilized world, political boundaries are more mutable and, yet, more important than ever. The role of local governments in responding to adaptation needs, for example, becomes increasingly acute even as it becomes more difficult to constrain climate effects from one territorially bounded unit to another. Equally, the role of national governments in advancing mitigation, adaptation, and loss-and-damage responses becomes ever more urgent even as the futility of acting domestically in the absence of global cooperation becomes clear. In this worst-case climate world, political, ecological, and planetary boundaries are increasingly in tension.

In a stubbornly stasis-oriented world, imagining how a worst-case climate will alter the physical, psychological, and political parameters of our world remains at the periphery of our legal imagination. But in this worst-case climate world, shifting boundaries challenge fundamental assumptions about how the rule of law operates at every level. Bringing these shifting boundaries into focus now allows us to envisage the role that law can play in averting crisis and advancing positive change in a worst-case climate world. It also forces us to ask whether law—with its predilection for boundaries and predictability—is the best tool for the task.

America Erased

Drought. Flooding. Extreme heat. Climate change has many tools for destruction, but no matter the disaster, in a 4° Celsius world, parts of the United States will be left uninhabitable. Significant portions of the population will be forced to leave their homes due to climate disasters and will live their lives as internally displaced people. These people will bring with them diverse cultural identities. They will also have left places of significant cultural and historical relevance. The locations may be lost, but the people will endure.

If the United States is to protect culture in the face of climate change, it must shift its focus towards protecting the culture that resides within those people. However, much of the current approach to protecting culture and history is rooted in protecting places. The paragon of this approach is the National Historic Preservation Act. Places deemed worthy of preservation are listed on the National Register of Historic Places, which has historically not been racially and gender inclusive, thereby failing to reflect the United States’ diversity. Places that have been recently added to address this lack of diversity are especially vulnerable to climate change.

Executive Order 13146 is an example of historic preservation beyond the National Historic Preservation Act. In the wake of Hurricane Floyd’s devastation of Princeville, North Carolina, President Clinton issued EO 13146 to recognize the historical significance of Princeville as the first city founded in the United States by freed slaves and to create the President’s Council on the Future of Princeville, North Carolina. However, memory is ephemeral, and until recently, the National Museum of African American History and Culture recognized Eatonville, Florida as the first town chartered by Black Americans. This error has since been corrected, and Princeville’s pride in being the first town chartered by Black Americans endures. Despite this previous inaccuracy, residents of Princeville are aware of their cultural significance and the value their community holds in American history.

Many residents of Princeville were relocated following Hurricane Floyd, but the town was rebuilt. Eventually, Princeville’s population returned to its levels prior to Hurricane Floyd. The town of Princeville had the option of a buy-out, but ultimately, the town rejected the buy-out. Princeville instead opted to rebuild its levees to protect it from the 100-year floodplain.

Unfortunately, the 100-year flood came 83 years early with Hurricane Matthew in 2016. Again, the town was flooded, destroying 450 homes. The population was only 2,200 at the time of Hurricane Matthew. The road to recovery has been long with many residents not wanting to abandon the historical significance of Princeville. Following Hurricane Matthew, North Carolina provided funding to purchase a total of 141 acres of neighboring land to relocate the most threatened parts of the town. However, in a 4-degree world, partial retreat will be insufficient. The places communities value most will be lost.

Princeville is an example of cultural and historical resilience. When their history was forgotten by other Americans, the people of Princeville remembered who they were as a community. The attachment to place will endure, but in the face of destruction, governments can choose to invest not just in protecting places, but also in the people who take pride in that culture and history. However, memory is ephemeral, and geography is a part of community identity. Once communities are dispersed, the United States risks losing that community identity and consequently the history and culture associated with that community.

Place is an important and complex aspect of individual and collective identity, but it is not the only source of identity. Geographic communities are just one type of community, just one classification existing among a multitude of identities. Culture and history can be protected if a cultural/historical perspective is taken towards communities. The geography may be lost, but the community will remain if protected. To protect this culture and history, the United States can choose to take an anticipatory or reactive approach to adaptation. The current approach is largely reactive, but an anticipatory approach is necessary to protect these resources [culture and history?] against the advancing threat of climate change.

Documents can be preserved. Oral histories can be recorded. But land, places that are slated to become uninhabitable in a 4-degree world, cannot be saved from climate change. What will happen if America chooses to continue emphasizing place in its approach to protecting and preserving history and culture? If people lose both their geographic community and the proximity geography provides to one’s social community, what culture and history will be lost? Will America take the anticipatory approach to preserving the culture and history existing within these communities? Or will America simply be erased?

In a 4°C World, the Inexorable Climate Change-Biodiversity Nexus

A 4°C world will reshape the human and nonhuman landscapes of the planet.  That’s axiomatic.  This reshaping, which we could have avoided, will now unfurl beyond our control: Seas will inundate, storms will destroy, drought will parch.  But within our control is how we reshape the landscape in response as we abandon, tear down, migrate, resettle, rebuild, mitigate, adapt.

The latest IPCC report, other blog posts in this series, and Robin Craig’s and J.B. Ruhl’s prescient, unhappiness-inducing article, 4 Celsius, lay out the consequences of a 4°C rise.  The latest report by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) (the IPCC’s more obscure cousin) predicts that more than one million species are imminently threatened with extinction. Those in the know increasingly warn that climate change exacerbates already dire human threats to biodiversity, rendering protected biodiversity redoubts no longer habitable but leaving no places to which to migrate.

As we needlessly hurl ourselves into the 4°C future and as we gobble ever more of Earth’s resources, climate change and biodiversity portend intertwined, grave threats.  Nonetheless, we think of these crises (when we think of them at all) in separate buckets: You over there, think about and tackle GHG buildup and responses; and over here, we’ll think about biodiversity loss. 

It’s time to multitask, to simultaneously envision how conserving biodiversity helps us mitigate and adapt to GHG buildup, and how mitigating and adapting to climate change can and must promote biodiversity. Both because these grave threats are braided and can and should be addressed symbiotically, and for practical reasons -- we only have so much time and money to invest to arrest these cataclysms and sustain a livable planet  we should therefore be merging our approaches to climate change mitigation and adaptation and biodiversity depletion. Think of it as biodiversity mitadaptation.  Biodiversity helps us mitigate GHG buildup; biodiversity helps us adapt to changing ecological regimes; efforts to mitigate GHG accumulation can help or harm biodiversity; and efforts to adapt to climate change can help or harm biodiversity.  In a 4°C future, we must pay a lot more attention to the inexorably linked climate-biodiversity mitadaptation nexus.

Jurisdictions’ pledges to achieve the Convention on Biological Diversity’s ambitious goal of 30% of land protected by 2030 could be synergistic if planners thought: How do our plans to reach 30x30 produce co-benefits if we think of biodiversity as mitadaptation?  How could our nascent plans for nature-based solutions to mitadaptation improve outcomes for biodiversity by specifically incorporating and putting biodiversity’s needs at the center? Because many biodiversity mitadaptation decisions are project based, we need not wait for international or national agreements to think holistically and synergistically.  Consider the following suggestions.

Hernandez et al. describe “techno-ecological synergies” when devising solar energy systems.  In response to mandates to reduce GHGs, large scale solar energy developers produce unintended consequences by scarfing down water and destroying biodiversity. By carefully planning where and how to develop solar and by mitigating the ecological degradation that solar development (currently pegged at nearly half the U.S. energy supply by 2050) causes, developers may minimize damage to biodiversity. For example, to account for demand for ecosystem services to support its solar energy development, the  community-owned Westmill Solar Park in the UK managed and achieved biodiversity benefits by planting native grasses to create pollinator habitat,which simultaneously increases transpiration under the panels, thus cooling them and generating energy more efficiently.

Building artificial, biodiversity-enhancing coral reefs may protect low lying coastal areas from storms and flooding.  In cooler climes, the Netherlands has long battled threatening seas and is now leading the world in learning to live with rising seas by using a “build with nature” philosophy.  The “sand motor” off the coast of the Netherlands provides a model of techno-ecological adaptation to climate change that explicitly attends to biodiversity.  In this pilot project, the Dutch harvested sand offshore (perhaps itself not a sustainable model) to build its buffer island.  The goals of the project explicitly include creation of new habitat for flora and fauna, and at its ten year anniversary, researchers found a rich diversity of shellfish and snails providing food for shorebirds.

Forests are the savior of GHG reduction goals; with net zero or carbon neutral targets depending on “offsetting” the carbon externalities of development, trees are repurposed as carbon sequestration devices.  But win-win-win programs under the aegis of REDD+ usually do not pay sufficient or any attention to biodiversity co-benefits. Ninety-two percent of tree plantation expansion in the tropics between 2000-2012 occurred in biodiversity hotspots, sometimes fueled by carbon offset funds, but seldom with biodiversity/climate change mitadaptation in mind.

When foresters restore land degraded by industrial logging or destroyed by fires, they usually emphasize rapidly growing monocultures and employ biocides to battle “weeds.”  That is, they prioritize short-term economic rather than ecological value. To quote one article, foresters can’t see the forest for the plantations.  The USDA considers it progressive evolution to plant trees uphill 500 feet from where a species has traditionally grown – a few steps uphill in the right direction, but not one that creatively imagines what a biodiversity rich forest will comprise in a 4°C world.  One British Columbia reforesting project, Seed the North, is “Fighting Climate Change, One Sprout At A Time.” They harvest seeds from land neighboring disturbed areas and employ indigenous people (and not just their knowledge) to harvest and cultivate the seeds.  They then use drones to drop diverse, biochar-encased seeds of native species over remote areas.  They aim to create vast carbon sinks composed of native species that sustain greater biodiversity and are better able to adapt to changing climate conditions.

Biodiversity itself may mitigate GHG accumulation.  Schmitz et al. show that animals regulate carbon exchange between the atmosphere and ecosystems in major, not always well understood ways. Predator/herbivore-prey/carbon relationships are complicated. For example, wolves in boreal ecosystems control moose populations, which through altered grazing intensity increase carbon retention in plants.  On the other hand, wolves that prey on elk in prairie ecosystems end up releasing more carbon to the atmosphere.  Living whales store tons of carbon, and their excrement nourishes carbon-sucking phytoplankton.  When whales die, and sink to the bottom of the ocean, they take their stored carbon with them. Forest elephants in Central Africa browse smaller trees, alleviating competition and allowing surviving trees to grow larger; researchers estimate that loss of elephants has decreased carbon stocks by 7% in their forest ecosystems.  

We do not have the time to ignore biodiversity as we mitadapt or to ignore mitadaptation when we effect biodiversity conservation. Nature-based solutions are also predicated on the notion that attending to functioning ecological communities makes human communities function better, as well.  Finally, and perhaps most importantly, it makes practical and economic sense to promote biodiversity when implementing climate change mitigation and adaptation goals, and vice versa.  If we are to survive this period of rapid ecological transition, we require a cultural paradigm shift where we see ourselves as fundamentally interconnected with the natural world.  The mitadaptation examples above demonstrate ways that our actions, policies, and laws could evolve to reflect and reenforce synergistic, holistic, systems-thinking imaginings.

Room for Nature

Professors Ruhl and Craig paint a vision of a 4ºC world marked by “discontinuous and often unpredictable transformation.” Nature, from climate to ecosystems to species, is hard to predict in the best of times. It’s a wild beast in a 4ºC world. This means that we will have to give up our efforts to tightly control nature and instead give her room. Room in a real, physical sense, like space for species to migrate and for seas to rise and for rivers to roam; and room in a metaphorical sense, by not harvesting and managing and controlling and consuming right up to the edge of destruction.

The only certain thing in this uncertain 4ºC future is change: The weather in many locations will be marked by increased variability, higher temperatures, more extreme precipitation events, and changes in total precipitation. Sea levels will rise. Storms will be more intense. In short, climate change will make many of our current climate expectations obsolete. Moreover, a 4ºC world does not just present a new set of stable conditions that society can assume will continue into the future; continuing unpredictable shifts in climate are a hallmark of a 4ºC world.

This is especially challenging because core aspects of our society, from infrastructure to farming to insurance to conservation, have been designed with the assumption of relatively predictable climate. Infrastructure, for example, is often tailored very narrowly to meet a predicted climate range, and flood insurance programs require levee protection designed to withstand a 100-year flood event in most areas. But in a 4ºC world, levees will face storms that exceed those design standards much more frequently than once every hundred years. We’ve often left ourselves a narrow margin of safety in all kinds of systems, from infrastructure to agriculture to environmental protection. This approach leaves little room for error, and the predictable climate that enabled this approach is ending. We’re moving into a climate that is predictably unpredictable. Our current world of just-in-time delivery, thin margins, efficiency, precise timing, and long supply chains is not built for the uncertainties of a 4ºC future. This problem extends to the ways we currently manage ecosystems, approaches that leave little room for nature itself.

Professor Dave Owen describes the prevailing ecosystem management ethos as “allow[ing] resource consumption right up to perceived brinks of illegality and . . . provid[ing[ just enough protection to avoid legal violations, but no more.” Managing at the brink of illegality is part of a broader problem of trying to manage natural systems within carefully delineated boundaries, under tight control. Of course, we actively manage ecosystems to protect particular species or provide particular ecosystem goods and services. But in many cases, as Professor Owen describes, we try to do so with little room for error, giving ecosystems only enough to deliver what we seek. Examples include just-in-time delivery of habitat for migrating birds, the deployment of just-in-time water management for fish protection, the provision of just enough protection for species to avoid a jeopardy opinion under the Endangered Species Act, and limitations on protections for desirable species to small habitat areas on the assumption that managers can unfailingly provide the precise conditions the species require.

The inclination toward these approaches is entirely understandable. They present the irresistible promise of using science, technology, and engineering in real time to meet the needs of nature while putting as few constraints on human activities as possible. Who doesn’t want more with less? In so many ways, it fits with our cultural zeitgeist. Even under current conditions, though, this approach often falls apart in the face of uncertainty and the inherent challenges of predicting natural system responses. And when these kinds of efforts fail, they generally place the burden of failure on ecosystems and species; they are not safe-to-fail approaches.

In an uncertain 4ºC world, tight management to achieve a narrow range of ecosystem conditions will be both increasingly expensive and increasingly impossible. The nature or character of an ecosystem is determined based on physical characteristics of the ecosystem, like precipitation, soil characteristics, temperatures, and on species availability (what gets introduced to the ecosystem) and the interactions between the species that find their way into the ecosystem. Changing any of those aspects of an ecosystem can produce a cascade of changes throughout the whole of the ecosystem, altering ecosystem aspects such as the abundance and kinds of species present as well as physical conditions in the ecosystem.

Climate change is already producing widespread changes in ecosystem conditions. Predicting exactly how a particular ecosystem will react to these changes is very difficult, but scientists can nevertheless predict that change is very likely. For example, based on increasing temperatures alone, more than one in every three local species in the Americas will be different in ninety years. The ecosystems that will develop in a 4ºC world are unpredictable, with no analog in today’s ecosystems, and tightly managing those ecosystems to provide desired outcomes will be tremendously, well, uncertain.

Instead, managers must approach ecosystem management with humility, not an expectation of understanding and control. What, precisely, does managing with humility mean? I’m excited to flesh that out in future work, but as a baseline, humility counsels leaving time and space for nature. Physical space: Space for new wetlands. Space for rising seas. Space for shifting floodplains. Space for fire. Space for new species. Space and time for natural processes to develop and shift and adapt. And metaphorical space: relaxed expectations about our ability to control nature and predict the outcome of management actions, more conservative estimates of how species will respond to conservation efforts, more leeway in estimating water needs for nature, less belief in the power of science and engineering to replicate natural systems.

In some ways, leaving space for nature fits well with our 4ºC infrastructure challenges.  Reconciliation ecology, defined by its originator Michael L. Rosenzweig  as “the science of inventing, establishing and maintaining new habitats to conserve species diversity in places where people live, work and play,” provides ways to integrate human and natural systems needs. Thus, to use one example, perhaps “space for wetlands and floodplains” becomes building sea walls and levees set far enough back from coasts and rivers to provide both improved flood protection and space for nature. Moreover, we must also consider how to integrate the inevitable human migration with healthy ecosystems: as people migrate to more hospitable places, we must leave room for nature in the new developments. And, although perhaps it is more restoration than reconciliation, as we manage our retreat from places made unlivable by climate change, we must not salt the earth, but rather rewild the lands and waters we leave behind.

Some states have begun to embrace this approach in their climate adaptation plans. California, for example, lists “prioritize natural infrastructure solutions” as one of its seven overarching principles for climate change adaptation and highlights the importance of restoration and conservation of natural systems to successful adaptation. This is a good start. But more broadly, we must recognize that tight controls of all kinds will fail in a 4ºC future, that the ecosystems of the future will not be the ecosystems of the present, and that nature needs space if it is to continue supporting life in the ways we have come to expect.

Compensation at 4° Celsius

Governments, and therefore taxpayers, could be saddled with enormous costs as global temperatures increase over the coming years. One aspect of these costs is the money governments in the United States must pay to private property owners as compensation if governments use eminent domain to acquire private property in order to modernize infrastructure to accommodate huge shifts in population density. Some obscure aspects of Compensation Clause doctrine might provide a roadmap for minimizing costs.

A ProPublica report from 2020 explains that there is an ideal human climate niche—an area with water, temperatures, and other climatic factors that make the area livable and productive. In the United States today, the ideal niche covers most of the eastern seaboard from southern New England to middle Georgia and stretches westward to about the western boarder of the Dakotas, Nebraska, and Oklahoma. As the world warms, that niche will shift northward. At 4°C warming, places like the Great Lakes region and central and the northern Appalachians will be among the only places left in the United States for significant human populations to persist.

When this shift happens, there will be massive population shifts with people migrating from “sending zones” like the coasts, the Southwest, and Southeast to “receiving zones” like the Great Lakes region. With population increases of possibly 200 million people in the receiving zones, governments will have to play a massive role to avoid chaos, preparing receiving-zone infrastructure to support transportation, housing, water management, and other necessities for dense, growing populations. The problem is that the Constitution can make this difficult.

The Takings Clause of the Fifth Amendment provides governments “eminent domain” authority to take property from private owners so long as the government puts property to public use. The takings power will be essential as governments acquire property for things like roads, reservoirs, treatment plants, mass transit, schools, police stations, military bases, shelters, cooling stations, and much more. Most of this infrastructure already exists, but dramatically shifting populations will require new concentrations of, and updates to, infrastructure in receiving zones. Fortunately, at least as an initial matter, the Constitution’s Takings Clause makes this massive infrastructure program possible because these uses clearly serve a public purpose apparent even to those who refuse to understand climate change.

Of course, the Compensation Clause requires governments to pay for any property they acquire through eminent domain. In that way, it makes sense to think of government takings as a forced sale of property. The government must pay the former owner fair market value for taken property. The U.S. Supreme Court has taken the Compensation Clause further and said that even if governments do not take ownership of property, they must still pay compensation if a regulation imposes a sufficient burden on the property. Therefore, whether a government intentionally takes ownership of property or designs regulations to address climate migrations, there will be a cost to this land-acquisition authority. This is particularly true considering that receiving zones will be among the only places where people can survive under a 4°C warming scenario and there will, therefore, be huge demand for property in these areas, pushing up values and the costs of government compensation.

How will the government afford to compensate property owners in a 4°C world, where the need for government intervention will be so stark?

There are two ways to approach this question. First, governments can capitalize on mass population shifts to raise money that will pay for compensation. With respect to this fundraising question, traditional strategies like raising tax revenue seem plausible, but the volatility of a 4°C economy might make the tax strategy difficult. Another option is to leverage newly available property in sending zones. If people are fleeing Florida because of flooding, Los Angeles because of drought, and Louisiana because of heat and humidity, governments may be able to obtain property in those areas at very low cost. The ability of a government to add value by taking and then consolidating land in sending zones might make the properties more attractive to speculators who are unwilling to take the risk of parcel-by-parcel acquisition but see value in consolidated tracts.

Second, governments can minimize the costs of compensation while remaining within constitutional bounds. This is a “doctrinal” strategy for reducing the costs of takings in the receiving zones. Courts measure just compensation by the fair market value of a property. Experts estimate what a willing buyer would pay a willing seller, and that is the amount the government pays the former owner. Although the calculation is not always simple, in practice the principle is at least easy to understand.

Things get more complicated when we are dealing with a “partial taking.” A partial taking occurs when the government does not acquire an entire property, but only part of the property, leaving the owner with a “remainder.” For example, in order to enlarge a road, a government might take 10 feet of property from 25 homeowners, leaving those homeowners with the majority of their property remaining in their possession. The government, of course, must pay for the slice of the lot it has taken, but factoring in the remainder property can change the calculation.

Suppose a government project, like the road widening, provides a financial benefit to the remainder property. The Supreme Court has written that “just compensation” must be just to both the person from whom the property was taken and to the public. In other words, while the government must pay, it must not overpay. If a government project creates a measurable benefit to remainder property, and the compensation does not account for that benefit, then the landowner may get a windfall from both the direct payment and an increase in the remainder property’s value. This is unjust for the public, which ultimately pays the compensation through tax dollars.

Over the years, the Court has developed a test for deciding what sort of benefits it will offset from compensation and what sort of benefits will leave the compensation unchanged. Broadly speaking, the Court allows “special benefits” to be subtracted from compensation, but it does not allow subtraction of “general benefits.” The way the Court has defined these terms is a jumbled mess, and certain doctrinal tweaks may be necessary to make the most sense of this area of law, particularly in light of the need for government intervention at 4°C. But the important concept is that certain types of government infrastructure and planning projects will generate enough clear and calculable financial benefit to remainder properties that the government will not have to offer any additional cash compensation.

This offsetting suggests a possible strategy for compensation at 4°C. When a government acquires property in climate receiving zones in order to make those zones inhabitable for vastly larger populations, the government should consider two things. First, governments should make efforts not to take entire properties. Leaving a remainder property creates a potential for reducing costs by generating benefits to the remainder. Second, governments should thoughtfully, carefully, and explicitly identify financial benefits to the remainder so that courts can easily understand the way a project provides in-kind compensation that can offset cash payments. There is little question that drinkable water, efficient transportation, public safety services, and reliable electricity provide significant benefits to property owners who rely on them. When properly structured, 4°C infrastructure projects can use these significant benefits to reduce the cost, keeping the United States functioning in the warming world.

Designing the 4ºC Electricity System to Achieve a 2ºC Future

In August, 2021, for the first time ever, the federal government declared a water shortage in the Colorado River basin. While the declaration was not necessarily surprising—the Colorado River has been in an official state of drought for the past 22 years and experts have demonstrated that drought conditions are, in fact, natural for the Colorado River basin—it served as a stark illustration of the “new normal” we have entered due to climate change. As Shi-Ling Hsu, Karrigan Bork, and Kevin Lynch argue in another Environmental Law Collaborative blog focused on 4ºC, this new normal will require reconsideration of the laws governing water rights.

It should also spur reevaluation of electricity system decarbonization models. For the past several years, a number of models have attempted to assess the technical and economic feasibility of rapidly decarbonizing the electricity system. Some models focus on pursuing “least-cost” strategies to reduce greenhouse gas emissions; others aim to demonstrate how the United States or areas of the United States could “electrify everything” through 100 percent renewable energy. All these models assume that hydropower will play a meaningful role in the decarbonized grid of the future. Although models do acknowledge that hydropower capacity will drop somewhat due to climate change,[1] others assume that hydropower will comprise nearly 40 percent of the Pacific Northwest’s electricity supply in 2050. But as droughts worsen due to climate change, these assumptions require reconsideration. Indeed, in 2015, an extended drought reduced California’s hydropower output by 59 percent compared to the prior two decades. This year, drought maps produced by the National Oceanic Atmospheric Administration (NOAA) showed that nearly all the hydropower facilities in the western United States were in drought conditions during the week of September 9, 2021. On the other end of the spectrum, more intense storms and floods are causing entire dams to fail. Whether due to too much or too little water, the nation’s hydropower supply is at risk. And these impacts are occurring when average global temperatures have climbed by only (only!) about 1ºC. If hydropower is becoming an increasingly unreliable resource today, it’s hard to imagine what it will look like at 4ºC.

But it’s not just hydropower; the energy system as a whole will be at risk as average temperatures rise. According to the Fourth National Climate Assessment released in 2018, already vulnerable aspects of our energy infrastructure will face intense challenges, if not complete destruction, at 4ºC. The impacts will go far beyond droughts and floods eliminating hydropower production. According to the climate assessment, in a 4ºC future, wildfires caused by electricity transmission lines will burn those lines down in return; power plants that need water for cooling will face forced outages to prevent overheating; severe wind and ice storms will knock over critical infrastructure or make it inoperable; and escalating energy demand during heat waves could trigger blackouts that result in heat-related deaths. While such projections may seem like speculative fiction, many of the predictions have already come true. Today, these consequences are infrequent enough to generate headlines, but they could become commonplace if we allow a 4ºC future to become our reality.

Avoiding these consequences of a 4ºC future requires us to plan for an energy system that can withstand a 4ºC future. Otherwise, we may not be willing to make, or even model, bold changes that could help us avert not just rising temperatures but the consequences of those rising temperatures. The current approach to energy modeling usually aims to pursue the lowest-cost strategies to achieve various rates of decarbonization. Through this modeling, energy planners assume that decarbonization should involve changes to the energy system we have today, namely by replacing existing fossil-fueled power plants with renewable facilities and, in some cases, nuclear power. Most of the models project that this transition will require a substantial expansion of the existing transmission system, and, as noted, most of them also assume that hydropower will provide a meaningful amount of energy into the future. While the models show that deep decarbonization through relatively modest changes is achievable, they fail to address how and whether a decarbonized energy system can be designed to minimize, or at least not exacerbate, harms to humans and the environment that our energy system has caused.

Let’s consider hydropower once again. Although hydropower can provide abundant amounts of emissions-free electricity (assuming water supplies are sufficient and the reservoirs do not release methane created through anaerobic decomposition of organic matter), dams have exacted an enormous toll on the environment—including on species that are at greatest risk of extinction due to climate change. The famed Federal Columbia River Power System, which supplies a substantial amount of electricity in the Pacific Northwest (and in California), has so altered stream flows and warmed waters in Oregon, Washington, and Idaho that almost all the species of salmon in the Columbia Basin are listed as endangered or threatened under the Endangered Species Act. Declining salmon populations are also linked to the imperiled status of Pacific orca whales, which feed on the anadromous fish. Declining stocks of salmon have also caused profound harm to Native American tribes, who for “time immemorial” have harvested salmon and called the wild Columbia River their home. None of this information, of course, is new. But the consequences of the dams on the species and people of the Pacific Northwest have been amplified by climate change, and they will only worsen as temperatures continue to rise. If we assume that those dams will remain in place and supply power in a decarbonized energy system, we must also assume the dams’ energy production outweighs the value of the salmon, orca, and Columbia River (and countless other western) Native American tribes. I, for one, cannot accept that calculation.

What’s worse, though, is that there is a good chance that the energy models’s projections of hydropower output are wrong. The decarbonization studies all acknowledge that future hydropower production is uncertain and that existing decarbonization models cannot precisely or accurately predict how hydroelectric facilities will function in an increasingly variable climate. Nonetheless, the models assume that existing hydropower facilities will provide necessary power well into the future. But if the models are wrong, then we will seek to decarbonize via “least cost” strategies, sacrificing endangered species and tribal rights, for no good. So long as the models assume the hydropower system will function more or less as it does now, those sacrifices seem, tragically, inevitable.

But what if modelers were charged instead with modeling a decarbonized energy system for a 4ºC world? In that world, large hydropower projects would almost certainly not play a role since their ability to provide electricity in drought-affected and flood-impacted areas would be highly uncertain. The hydropower capacity in today’s decarbonization models would be replaced with other zero-emitting resources in the energy system designed for a 4ºC future, and, ideally, the dams would be removed and free-flowing waters would be restored. Of course, if we wait for 4ºC to be locked in, the salmon, the orca, and a host of other species will be gone, and the tribes will suffer even more. So, let’s not wait. Instead, let’s jettison narrow “least-cost” approaches to energy decarbonization that ignore the massive costs our current energy system already imposes on habitats, species, and humans. While tradeoffs are inevitable and there are likely no ways to decarbonize that do not exact some toll on humans and the environment, we can at least aim to eliminate the most destructive facilities.  Let’s start planning for a decarbonized electricity system that can operate in a 4ºC world so that species and people have a chance in a 2ºC one.

[1] For example, a deep decarbonization model for California estimates an 11% decrease in hydropower output from 2015-2050. The authors of the report recognize that hydroelectric production will likely not decrease linearly and will vary on a seasonal basis, but explain that their decarbonization model cannot incorporate such variability. (pp. 25-26.) As a result, hydropower is projected to provide about 9% of total energy supply in 2050, down from about 10% in 2015.

Western Water Rights in a 4°C Future

Western water rights reflect a short and stable climate history, but that period of stability is ending. Looming climate change of 4°C will produce not only higher temperatures, but decreased snowpack, shifts in runoff patterns, and the dramatic shrinkage of giant reservoirs. The climatic changes that have already traumatized the West will only intensify and cross even more dangerous thresholds, necessitating the deliberate adaptation of water rights systems.

Hydrology in a Changing Climate

A climate-changed future is inherently uncertain, but a general consensus predicts a dire future for water supply in the arid West.  Precipitation patterns are the biggest source of uncertainty due to the potential increase in extreme weather events.  This could both increase and decrease water supplies as larger snowstorms could dump more precipitation in some years, while other impacts on the snowpack would lead to declines.  However, higher temperatures in the summer and fall are expected to offset potential increases in snowpack in most years, leading to an overall trend of less water supply in a warming future.  The Colorado River, which supplies vital water to seven states and 23 tribal nations, may experience flow losses due to temperature increases by more than 20 percent midcentury and 35 percent by 2100.  Intra- and inter-annual variability will continue as a hallmark of western water systems. In the Colorado River basin, for example, the impacts of a changing climate are already apparent as the current megadrought fueled by climate change recently led to the first ever federal water shortage declaration.  Experts urge us to plan for even worse impacts to come.

Looking beyond the Colorado River basin, a 4°C world leads to large declines in snowpack in the western United States, perhaps in the range of a 40 percent decrease due to generally less precipitation and shifts from snow to rain.  The snowpack in the Sierra Nevada mountains recently hit its lowest point going back at least 500 years. Decreasing snowpack reduces water availability throughout hot, dry summers, resulting in significant seasonal water shortages.

Warmer temperatures and less frequent precipitation also mean that even normal snowpacks do not necessarily bring relief from droughts.  For example, Colorado’s 2021 snowpack was almost normal, but because soils in many western watersheds were unusually dry, most of the water went into the soils and not into streams, rivers, and reservoirs for human uses.  Another driver of drought in a warming world is the increase in evapotranspiration caused by higher temperatures as plants need more water and evaporation from rivers and reservoirs increases. These factors point towards a drying and warming future in the southwestern United States, particularly in the Colorado River basin.

Water Law Historically Adapted to Hydrology

The changes in the West’s hydrology are very likely to produce changes in water law, which has historically evolved in response to differing climactic conditions. Early U.S. water law decisions drew heavily on English water law, establishing a system based on riparian water rights. Riparian rights come from ownership of land that abuts a watercourse, and they are generally limited to reasonable use of the water on the riparian land. Riparian rights have many other limits; they do not allow storage or long distance transportation of water, for example, and they are not absolute, leading to some uncertainty about the quantity and reliability of water. These limitations meant that riparian rights were poorly suited to western hydrologic regimes where seasonal (and total) water availability patterns require storage and transportation of water to maximize the benefits of available water.

California developed a system of appropriative rights based on the use of water, not on land ownership. Appropriative rights allow water storage and transportation, and these advantages led all of the states west of the Mississippi to adopt some version of appropriative rights. Coastal states like California and Washington, and midwestern states like Kansas and Nebraska, tend to blend riparian and appropriative doctrines, while drier western states like Colorado embrace a purer appropriative rights approach that does not recognize riparian rights at all. Appropriative water rights systems give priority to the first user of the water, an approach often styled “first in time, first in right,” so that later users may not get their full allocation of water in dry years. Maintaining appropriative water rights requires constant vigilance; these rights can be lost through disuse or to other users who take the water. Water rights are tied to the land and to its use; transferring the right to someone else or changing the place or use of the water generally requires permission of a state level water agency.

The appropriative rights and the blended appropriative/riparian rights approaches are both inherently based on historic hydrology and patterns of land use and ownership. This can make them a barrier to climate adaptation. For example, the first-in-time approach gives priority to the earliest water users, regardless of how well suited these uses are to a changing climate or changing societal needs.  Historical aspects of water rights thus sometimes allow lower value agricultural uses to take priority over domestic and industrial uses. Formally, water use is generally required to be reasonable and beneficial, but as a practical matter, courts and water boards rarely rein in inefficiency. Recent droughts have shown many existing uses of water to be even more anachronistic. Because most water in the West is already appropriated, in a drier, climate-changed future, a reordering of priorities seems necessary.

Consider California’s agricultural sector. Though productive and valuable, California's agricultural sector constitutes about 80 percent of the state's human water use while accounting for less than 3 percent of the State's GDP. The ag sector has become significantly more efficient in the last 30 years, using less total water to produce more agricultural value. Nevertheless, in some cases and in some years, California water currently used in agriculture would be more valuable as drinking water or as water to support ecosystems. Growing fewer almonds or making less milk and cheese will likely be necessary in a 4°C world. A successful water rights system should encourage and accommodate these shifts.

Further, use-it-or-lose-it requirements disincentivize water conservation or land use changes that could free up water for other users.  Riparian rights give strong rights to riparian landowners, a system that tends to maintain existing land uses and perpetuate distributive justice concerns. Use-based appropriative rights inherently value use over conservation or other "passive" uses, such as fish and wildlife habitat.

Finally, although existing water rights systems have succeeded in spurring economic development, they have done so at great environmental and social cost. The extensive, massive water diversions that have made California the most productive agricultural state in the United States also completely transformed the entire Central Valley and altered the ecology of much of the state, driving many native species to extinction.

Can Water Law Adapt to a Warmer Future?

How is the western United States to cope with a world that is warmer by as much as 4°C and chronically short of water? We suggest three steps, emphasizing that these represent just a few out of many constructive actions that might be taken to prepare for a much warmer, much drier American West.

New diversions must be evaluated under a conception of reasonableness that includes climate change. Western water law has always embedded notions of reasonableness and almost always been, at least formally if not in practice, predicated on some consideration of public interest. These terms have been either ill-defined or defined in a way that gives short shrift to considerations of conservation and passive uses. The phrase public interest has been infrequently deployed to protect passive or instream uses and has in some cases simply been ignored in water permit applications. Notions of reasonableness or beneficial use must take account of future scarcity of water and an increased need for conservation and domestic uses.

Existing reasonableness requirements must be enforced as a limit on current water rights. With climate change already well underway, many existing allocations of water are economically inefficient, with too little regard for non-agricultural uses. Because most water in the West is already allocated, current water uses must be re-examined and curtailed if they fail to meet a realistic reasonableness test that accounts for the drier, hotter realities of a climate-changed future.

States must actively secure water rights in preparation for severe and prolonged water shortages in the future. States must create new institutions to collect water rights as an effective stockpile against future scarcity, which may present more serious threats than the loss of crops or livestock. States must migrate some water and water rights into a governance mechanism that operates outside of traditional water law. A state-chartered trust instrument, such as a "Resources Trust," might be legislatively charged with gathering up water and water rights in order to act as a water supplier of last resort should the dire need arise. In hedging against severe and prolonged water shortages, such a Resources Trust might employ a range of legal instruments, such as options, to secure future supply.

Adapting to a 4°C World: Essays from the Environmental Law Collaborative

The Environmental Law Collaborative (ELC) comprises a rotating group of law professors who assemble every other year to think, discuss, and write on an important and intriguing theme in environmental law. The goals of this meeting are both scholarly and practical, as ELC participants seek to use their disparate areas of scholarly expertise to study trends and important events in the law and ultimately to improve the environmental conditions of the world in which we live. 

Participants at the ELC’s most recent meeting in July 2021 were asked to consider the adaptation challenges of the worst-case climate scenario: a world that warms to 4°C by 2100. As environmental law professors, we remain dedicated to the study and support of laws and policies designed to mitigate greenhouse gas emissions and avert the worst-case scenario. But we cannot ignore what scientific studies and newer climate models show. The Paris Agreement’s goal to hold warming to 1.5° – 2°C above preindustrial levels now appears unrealistic. In the United States, regulatory inaction and political gridlock frustrate efforts to implement the decarbonization measures that we need now to prevent the warming predicted by climate models. At the international level, the commitment and cooperation necessary for dramatic emissions reductions also appear unlikely.

To frame and inspire discussion about the consequences of a 4°C world, participants read a recent article by two ELC members, Robin Kundis Craig and J.B. Ruhl, who argue that because a 4°C world is likely, we must recognize the disruptive consequences of such a world and respond by reimagining governance structures to meet the challenges of adaptation. A 4°C world is one marked by dramatic sea-level rise, devastating heat waves, extreme drought, increased flooding, food insecurity, and radical shifts in ecosystems and biodiversity. Some communities may not be able to adapt; they may simply have to move. Adapting our laws and governance structures to physical and social disruption at this scale requires transformative thinking.

In the blog posts we will share this month, ELC participants explore what it means to adapt to a 4°C world. Some posts highlight the inadequacy of current legal doctrines, planning policies, and governance structures to meet the adaptation challenges ahead. Others examine the need to rethink laws and institutions that govern ecosystem services and issues of biodiversity. And some focus on issues of social equity and environmental injustice. Although each post makes its own contribution, they share a deep concern for the future and an urgency to mitigate not only the emissions that drive us closer to 4°C, but also the serious harms that we will suffer if we fail to plan for the worst-case scenario.

Takings Litigation in the Court of Federal Claims and the Federal Circuit

Earlier this year, in his dissenting opinion in Cedar Point Nursery v. Hassid, Justice Breyer wrote that “most government action affecting property rights is analyzed case by case under Penn Central’s fact-intensive test.” That statement reflects conventional wisdom. Supreme Court justices have often said similar things, as have many academics. They tend to assume—with some exceptions—that the most prevalent cases and the most intellectually challenging and important questions arise from regulatory takings jurisprudence, with the Penn Central standard governing most of the action.

But for takings cases against the federal government, that conventional wisdom is wrong. I recently compiled a database of takings claims filed in the United States Court of Federal Claims—which hears almost all takings claims against the federal government—between 2000 and 2014. The database tracks cases from filing to completion, and it includes data on numbers of plaintiffs, numbers of different types of claims, case outcomes, and the amount of money paid by the federal government, sometimes through court judgments but usually as part of settlements. The resulting study is now available here. It will be published next year in the BYU Law Review.

The resulting findings confirm conventional wisdom in some ways, but in others they contradict it. Among the findings I found most interesting:

  • During the study period, the overwhelming majority of takings claims filed against the federal government were for alleged physical takings.
  • Three categories of cases—rails-to-trails conversions, military overflight cases involving a single base in Virginia, and flooding cases—accounted for 91% of all of the takings claims filed. More than half of the plaintiffs were involved in rails-to-trails cases.

Numbers of takings plaintiffs (total n = 11,693)

Plaintiffs chart

  • Almost three quarters of the just compensation paid to date was in rails-to-trails cases. I found documentation of 336 million dollars in just compensation (normalized to 2020 dollars) from those cases, with some cases still ongoing and some settlements that I was unable to find and that the Department of Justice could not produce.

Just compensation payments (total = $453,058,985)

Payments chart

  • Penn Central and Lucas analyses were relatively rare, and plaintiff victories on regulatory takings claims were exceedingly rare. I found only four successful regulatory takings claims.
  • I did not find any cases in which a plaintiff succeeded under a Nollan-Dolan-Koontz exactions analysis. Discussion of those cases hardly ever came up.
  • An issue that arises frequently in Court of Federal Claims cases—and much less frequently in United States Supreme Court jurisprudence—is whether the plaintiff actually holds a property interest in the thing that was allegedly taken. That means the Court of Claims often addresses questions—some of them intriguing—about what counts as property, and how courts should decide.
  • Another recurring issue is what mode of takings analysis should be applied. In a range of fields—most notably, litigation over regulation of water use and litigation over post-Great-Recession management of Fannie Mae and Freddie Mac—a key threshold question has been whether to analyze claims as regulatory restrictions, which would receive a Penn Central analysis, or as appropriations, which would likely mean a categorical analysis.

Another finding sweeps more broadly. In the 1980s and 1990s, many conservative activists hoped, and many liberals feared, that takings litigation would hobble the regulatory state. The goal, or the worry, was that widespread litigation would force government to pay compensation for much of its regulatory work, which would make regulation a whole lot less likely. At the federal level, and during the time period I studied, there is scant evidence that takings litigation has played that role. Most federal regulatory agencies have been largely untouched by takings litigation, and big business brings very few takings cases. Struggles over the extent of government regulation remain central to our political and legal systems, of course, but the most important struggles are not playing out through takings litigation.

I think the study raises as many questions as it answers, and the biggest unanswered question is whether a similar study of takings litigation against state and local governments would produce similar results. For this study, I could not answer that question; databases of state-court complaints were very incomplete, which meant I could not search for state-court takings complaints in any sort of systematic way.  James Krier and Stewart Sterk’s excellent study of state-court takings decisions suggests that regulatory takings cases are more prevalent in state court than they are in federal court, though it is possible the numbers might shift (in either direction) if one looked at the numbers of plaintiffs who file cases rather than at numbers of published decisions.  But even if the Court of Federal Claims’ takings docket may be an outlier, it’s a big, important outlier. The federal government is an influential regulator, to say the least, and takings litigation against it should be a focus of academic and judicial interest.

Again, the full study is available here. It still is in draft form, and comments are welcome.

Environmental Law Faculty Hiring Information

Each year, I write a post listing schools that are interested in hiring tenured or tenure-track environmental law faculty.  This year's list appears below. 

Readers should be aware of a few things about this list.  First, it is limited to tenured, tenure-track, and long-term-contract hiring.  I haven't made an effort to identify visiting positions.  That's because visiting positions tend to open up later in the academic year.

Second, this list may grow in the next few weeks, and I'll continue updating the post if it does, but it's also likely to remain incomplete.  I've compiled the list by looking at Prawfsblawg's post on entry-level hiring committees and by soliciting input from the environmental law professors' listserve.  There may be interested schools that (a) didn't post their interest on Prawfsblawg; (b) don't have faculty members on the listserve; and/or (c) choose to keep their hiring preferences to themselves.  Strong environmental law candidates therefore may draw interest from schools that aren't listed below.

Third, schools that are interested in environmental law hires are probably also looking at other subject areas.  They may hire in those areas rather than environmental law, and they also may not hire at all.

With those qualifiers, here’s the list.  It’s relatively long, which hopefully means this will be a good year for environmental law hiring. 

Alabama is looking for three tenure-track hires, and environmental law/regulatory compliance is one of its areas of primary interest.

Berkeley is looking in a range of areas, including energy and environmental justice.

On Prawfsblawg, Case Western says it is seeking an “instructor to run an environmental law clinic.”

Colorado hopes to hire an environmental law/natural resources law professor.

Columbia is searching for a new director for its environmental law clinic.

Emory is looking to hire a entry-level or junior lateral tenure-track faculty member specializing in environmental law.

Florida State is looking for an environmental law hire, who could be entry level or lateral (a lateral hire might be eligible for a distinguished chair).

George Washington will be hiring in several areas, including environmental and energy law.

Georgetown may be looking in the environmental field.

On Prawfsblawg, Hofstra lists environmental law as one of its secondary areas of interest

Indiana-Indianapolis is hiring for an endowed chair in environmental law.

Minnesota has posted a general search, and environmental law is one of its areas of interest.  It is focusing on entry-level and junior lateral candidates.

New Mexico is seeking to hire an entry-level professor in its environmental and natural resources law program.  The position will include some rotations teaching in the school's environmental law clinic.

Temple is hiring, with environmental and energy law among its areas of interest. Candidates who also can teach torts, race and the law, or other racial justice classes will be particularly appealing.

Tulane is seeking a chair (in other words, an established scholar) in environmental law.

Utah is looking for two environmental candidates—one a lateral, and the other an entry-level civ pro person who ideally also would have expertise in environmental law.

Vermont appointments chair Hillary Hoffman writes: “we will be making several hires this year in E-law.  Staff attorney/Assistant Professor in the Environmental Advocacy Clinic, Environmental Justice Clinic Director/Assistant/Associate/Professor of Law (new program), Animal Law Program Director/Assistant/Associate/Professor of Law (new program), Institute for Energy & Environment Associate Director/Assistant/Associate Professor of Law.”

Some New Environmental Law Faculty Hiring Information

Last fall, we ran a post about schools looking to hire environmental law professors, or people in related fields.  In the last few weeks, schools have posted more information about that subject.  The latest:

Maine is looking for a visitor to teach property, and that person might also have environmental law interests.  The announcement is here.  I taught in Maine for eight years, and I can vouch for the school, the city of Portland, and the state as a wonderful place to spend a year (or more).

Wyoming is looking for a visitor to teach torts, another subject that overlaps nicely with environmental law.  Interested candidates should email Michael Duff (Michael.Duff@uwyo.edu) or Sam Kalen (skalen@uwyo.edu).

Iowa recently announced that it is looking for a lateral hire in environmental law.  I didn't see the announcement on the school webpage, but you can find it here, among other places.

John Cruden Receives ABA SEER Lifetime Achievement Award

John Cruden, who among many other things was a longtime Justice Department leader in the Environment and Natural Resources Division, was awarded the Lifetime Achievement Award for Environmental Law on October 20 by the American Bar Association (ABA) Section of Environment, Energy, and Resources.  At the Justice Department, John first led the Environmental Enforcement Section before being promoted to Deputy Assistant Attorney General and eventually being named Assistant Attorney General under President Obama.  In addition to his Justice Department service, John also has served as the president of the D.C. Bar, chief legislative counsel for the Army, president of the Environmental Law Institute, chair of ABA SEER, and president of the American College of Environmental Lawyers. He continues to practice environmental law as a principal at Beveridge & Diamond PC in addition to teaching at The George Washington University and Santa Clara University law schools.  Those of us who have worked with John in any of these roles know and appreciate the integrity, diligence, intellect, and wisdom he brings to his work.  It is hard to imagine environmental law without John Cruden's contributions.  This award is extremely well deserved, especially during these times when those in government service are facing so many challenges.
