Global Warming Projection Worse than Thought: MIT

Important and reputable estimates of green house gas-induced warming have substantially increased to more than 10 times the increase in the last century and way above the rates of 1 degree C that has been the reference for all of the climate change discussions.

To repeat, on our current emissions path, we have a 9% chance of an incomprehensibly catastrophic warming of 7°C by century’s end, but less than a 1% chance of under 3°C warming.

“The take home message from the new greenhouse gamble wheels is that if we do little or nothing about lowering greenhouse gas emissions that the dangers are much greater than we thought three or four years ago,” said Ronald G. Prinn, professor of atmospheric chemistry at MIT. “It is making the impetus for serious policy much more urgent than we previously thought.”

The time to act is now.
