|summarize what the recent scientific literature says are the key impacts we face in the coming decades if we stay anywhere near our current emissions path. These include:
Staggeringly high temperature rise, especially over land -- some 10 -F over much of the United States
Permanent Dust Bowl conditions over the U.S. Southwest and many other regions around the globe that are heavily populated and/or heavily farmed.
Sea level rise of some 1 foot by 2050, then 4 to 6 feet (or more) by 2100, rising some 6 to 12 inches (or more) each decade thereafter
Massive species loss on land and sea -- perhaps 50% or more of all biodiversity.
Unexpected impacts -- the fearsome 'unknown unknowns'
Much more extreme weather
Food insecurity -- the increasing difficulty of feeding 7 billion, then 8 billion, and then 9 billion people in a world with an ever-worsening climate.
