In Spring 2014, we conducted our latest national survey on Americans’ climate change and energy beliefs, attitudes, policy support, and behavior.
The first report shows that of those Americans who think global warming is happening, nearly two in three (62%) say they are either extremely (30%) or very (32%) sure that it is. Three years ago, in May 2011, fewer (54%) were as sure. Also, Americans continue to be unaware of the extent of scientific consensus on climate change. Only one in ten Americans (12%) know that 90% or more scientists have concluded human- caused global warming is happening. More than twice as many Americans – about three in ten (28%) – think fewer than half of climate scientists have reached this conclusion.
