The environmental community is mobilizing to get Obama to reject imports of oil produced from tar sands. While the campaign primarily focuses on the climate change impacts, the most pernicious effects of tar sands production are on water, both in terms of water quality and water allocation. Tar sands production requires huge amounts of water and the water becomes polluted to the point where it is largely uneconomic to clean it: essentially permanently polluting freshwater resources, which are already limited. On these grounds alone, we should not encourage development of tar sands. In addition, tar sands and other "secondary" forms of oil production, all contribute more to global warming than conventional oil. We must be prepared for Canada's response: the U.S. is being hypocritical unless it also discourages production of oil shale in the Mountain West -- another secondary recovery source of oil. And the answer to that needs to be -- yes, we need to get our own house in order and develop a marketable carbon rights program or carbon tax that forces energy corporations to realize that development of such resources is both socially undesirable and economically infeasible.

(Seattle, WA) -- On February 19, President Barack Obama
travels to Canada on his first international trip as
President, where he will face pressure from the
Government of Canada to support production of Alberta's
filthy tar sands oil. An international network of
environmental groups has launched the "Obama2Canada"
campaign urging President Obama to stand strong on his
new energy economy agenda and reject entreaties from
Canadian Prime Minister Stephen Harper to shelter the
dirtiest oil on earth from global warming regulation.
"Tar sands oil is the dirtiest form of energy in the
world. It has no place in President Obama's plans for a
clean energy economy," said Sierra Club Dirty Fuels
Campaign Coordinator Pat Gallagher. "Tar sands oil
accelerates global warming. It destroys forests. It
endangers public health. Instead of importing this
expensive, dirty oil, we can invest in clean energy that
will create millions of much-needed, sustainable jobs."
Called oil sands by proponents, tar sands are the very
dirtiest of fossil fuels. Producing oil from tar sands
emits three times the global warming pollution as
conventional oil, requires excessive amounts of energy
and fresh water, and destroys huge swaths of ancient
boreal forest. Given its massive carbon footprint, tar
sands would almost certainly prove unviable under any
reasonable climate change regulations. Along with ending
the use of coal and old growth forest destruction,
stopping tar sands is essential global climate policy
required to maintain an operable atmosphere.

On Saturday, I noted the AAAS meeting report on climate change by Christopher Brown.Climate change worsens more rapidly than IPCC anticipated Here's a bit more on Christopher Field's report from MSNBC:
Carbon emissions have been growing at 3.5 percent per year since 2000, up sharply from the 0.9 percent per year in the 1990s..."It is now outside the entire envelope of possibilities" considered in the 2007 report of the International Panel on Climate Change...The largest factor is the widespread adoption of coal as an energy source... "and without aggressive attention societies will continue to focus on the energy sources that are cheapest, and that means coal." Past projections for declines in the emissions of greenhouse gases were too optimistic, he added. No part of the world had a decline in emissions from 2000 to 2008.
Anny Cazenave of France's National Center for Space Studies [reported] that improved satellite measurements show that sea levels are rising faster than had been expected... Rising oceans can pose a threat to low level areas such as South Florida, New York and other coastal areas as the ocean warms and expands and as water is added from melting ice sheets...And the rise is uneven, with the fastest rising areas at about 1 centimeter — 0.39 inch — per year in parts of the North Atlantic, western Pacific and the Southern Ocean surrounding Antarctica...
