Americans’ Global Warming Beliefs and Attitudes in April 2013


http://environment.yale.edu/climate-...fs-April-2013/

Nearly two in three Americans (63%) believe global warming is happening. Relatively few – only 16 percent – believe it is not. However, since Fall 2012, the percentage of Americans who believe global warming is happening has dropped 7 points to 63%, likely influenced by the relatively cold winter of 2012-13 in the United States and an unusually cold March just before the survey was conducted.

• About half of Americans (49%) believe global warming – if it is happening – is caused mostly by human activities, a decrease of 5 points since Fall 2012, but similar to levels stretching back several years.

• More Americans believe that “most scientists think global warming is happening than believe there is widespread disagreement among scientists (42% versus 33%, respectively).
