Global Warming Risk Analysis

A study published by Scholze in PNAS does a risk analysis of the impacts of climate change on major ecosystems, including freshwater resources, forest and desert shifts, wildfire, precipitation and soil loss from runoff.  The study looks at three 21st century scenarios: a increase of mean global temperature under 2 degrees C, 2-3 degrees C, and more than 3 degrees C.   As one would expect, higher impacts occur with larger increases -- at more than 3 degrees, the land carbon sink loses its effectiveness (one of those cliffs).  The impacts continue to increase for another 200 years even if carbon emissions are held constant.
