An overwhelming number of scientists (84%) say the earth is warming because of human activity, while just 4% of scientists say there is no solid evidence the earth is warming. Yet only 56% of Americans say that scientists agree that global warming is real and man-made, according to Pew Research survey data.
Although only 11% of the American public see no evidence the earth is warming, only 49% attribute the warming they see to human activity; the other 36% ascribe it to natural causes, according to Pew Research data. The public’s perception of where the scientific community stands on climate change is tied to their own opinions on the issue, according to Pew.
In a July Pew Research survey, about half the public (49%) said human activity is creating global warming. (An October Pew Research survey found far fewer Americans seeing solid evidence that humans are causing global warming.) Among this group, three-quarters (76%) said that scientists have reached a consensus on climate change and its cause. Among the 36% of Americans who said global warming is real but due to natural causes just 41% said there was a scientific consensus on the issue. And among those who said there is no evidence of climate change (11% of the public) a strong majority (68%) said there is no agreement among scientists on global warming.
About one-in-five global warming skeptics (22%) say there is scientific agreement that human activity is causing climate change.
