Most Americans don't believe humans responsible for climate change, study finds

In contrast, scientists overwhelmingly believe global warming is caused by human activity

Barack Obama's sense of urgency in getting Congress and the international community to act on climate change does not appear to have rubbed off on the average American, a new study published today reveals.

Even as the president pressed the G8 and the world's major polluters to resist cynicism and the pressure of the economic recession to act against global warming, a majority of Americans remain unconvinced that humans are responsible for climate change, or that there is an urgent need to act.

About 49% of Americans believe the Earth is getting warmer because of the burning of fossil fuels and other human activity, the survey by the Pew Research Centre and the American Association for the Advancement of Science said. Some 36% attributed global warming to natural changes in the atmosphere and another 10% said there was no clear evidence that the earth was indeed undergoing climate change.

Scientists in contrast are overwhelmingly persuaded that global warming is caused by humans - some 84% blame human activity. A strong majority - some 70% - also believe it is a very serious problem. Despite that degree of consensus, some 35% of Americans continues to believe - wrongly it turns out - that climate change remains a matter of scientific controversy. Only about 47% of the public views climate change as a very serious problem, a finding that has remained stable over the years, the survey said. In other public opinion polls over the years, climate change has ranked near the bottom of the list of pressing problems.

The Pew poll, like others in the past, also found attitudes towards climate change breaking down according to political allegiance. Some 67% of Republicans either deny the existence of climate change or attribute the phenomenon to natural causes. In contrast, 64% of Democrats believe that the earth is getting warmer because of human activity.

Survey Shows Gap Between Scientists and the Public

When it comes to climate change, the teaching of evolution and the state of the nation’s research enterprise, there is a large gap between what scientists think and the views of ordinary Americans, a new survey has found.

On the whole, scientists believe American research leads the world. But only 17 percent of the public agrees, and the proportion who name scientific advances as among the United States’ most important achievements has fallen to 27 percent from nearly 50 percent in 1999, the survey found.

And while almost all of the scientists surveyed accept that human beings evolved by natural processes and that human activity, chiefly the burning of fossil fuels, is causing global warming, general public is far less sure.

Almost a third of ordinary Americans say human beings have existed in their current form since the beginning of time, a view held by only 2 percent of the scientists. Only about half of the public agrees that people are behind climate change, and 11 percent does not believe there is any warming at all.

According to the survey, about a third of Americans think there is lively scientific debate on both topics; in fact, there is no credible scientific challenge to the theory of evolution and there is little doubt that human activity is altering the chemistry of the atmosphere in ways that threaten global climate.

The survey, by the Pew Research Center for the People & the Press and the American Association for the Advancement of Science, the world’s largest scientific organization, involved about 2,000 members of the public and 2,500 scientists drawn from the rolls of the science advancement association, which includes teachers, administrators and others involved in science as well as researchers.

The survey, made public Thursday, is available at people-press.org.

It found that at least two-thirds of Americans hold scientists and engineers in high regard, but the feeling is hardly mutual.

The report said 85 percent of science association members surveyed said public ignorance of science was a major problem. And by large margins they deride as only “fair” or “poor” the coverage of science by newspapers and television.

Only 3 percent of the scientists said they “often” spoke to reporters.

In a telephone news conference announcing the survey, Alan I. Leshner, chief executive of the science association, said scientists must find new ways to engage with the public.

“One cannot just exhort ‘we all agree you should agree with us,’ ” Mr. Leshner said. “It’s a much more interactive process that’s involved. It’s time consuming and can be tedious. But it’s very important.”
