Quote from Dr. Caldeira:
"We took a model and emitted all of the carbon dioxide available in fossil fuel resources, and that model — which has a very low climate sensitivity, and what I would consider a hyperactive land biosphere — produced 9-degree Centigrade warming globally and 20 degrees around East Antarctica.
Now that’s 16 degrees Fahrenheit globally, and something like 36 degrees around Antarctica, which could be enough to threaten the ice sheet."
I think that means it will get hot. And the polar caps would melt. That's enough of a problem for me.
