83% of Americans believe Earth is warming

Jon Krosnick, professor of communication and  political science of Stanford University, has released the latest Stanford University with Ipsos and Reuters survey on public opinion on global warming. 5 out of 6 Americans (83%) believe Earth is warming, 15% say it is not. That is up from 75% in 2010.

Almost three-quarters (72%) of Republicans believe global warming has been happening, as do 92% of Democrats. The percentage of Americans who are certain that warming has been happening has also climbed, from 45% to 53%. Those who do not believe in global warming have become more resolute in their attitude (certainty from 35% in 2010 to 53% in 2011).
