NASA: Global Warming Likely To Be 20% Higher Than Previous Thought

NASA: Global Warming Likely To Be 20% Higher Than Previous Thought reports Joe Romm at Climate Progress. The temporary slowdown of atmospheric (not global, which includes oceans) warming is partly due to to cooling effect of particulate pollution over land in the Northern Hemisphere, note John Abraham and Dana Nuccitelli at the UK Guardian. That cooling effect has been underestimated, meaning that the warming effect it masked was also underestimated. This affects the lower end of predicted warming, estimated at 3 to 9 oF; the new findings indicate that it will more likely warm between 6 to 9 oF, especially as aerosols decline and greenhouse gases rise. Another reason to switch to clean energy ASAP.

Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: . This is an ongoing campaign (the next Congressional election is this year!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
