The number of Americans who believe that global warming is happening and are concerned about it are on the rise, according to a new national survey by researchers at Yale and George Mason Universities.
Since January, public belief that global warming is happening rose four points, to 61 percent, while belief that it is caused mostly by human activities rose three points, to 50 percent. The number of Americans who worry about global warming rose three points, to 53 percent. And the number of Americans who said that the issue is personally important to them rose five points, to 63 percent.
The stabilization and slight rebound in public opinion is occurring amid signs the economy is starting to recover, along with consumer confidence, and as memories of unusual snowstorms and scientific scandals recede, said Anthony Leiserowitz, director of the Yale Project on Climate Change Communication. The BP oil disaster is also reminding the public of the dark side of dependence on fossil fuels, which may be increasing support for clean energy policies.
Earlier this year, polls showed public confidence in global warming science was eroding. See here:
The poll also shows that Americans who said President Obama and Congress should make developing sources of clean energy a high priority increased 11 points, to 71 percent, while those who said that global warming should be a high priority rose six points, to 44 percent. In a seven-point increase since January, 69 percent of Americans said that the United States should make a large or medium effort to reduce global warming even if it incurs large or moderate economic costs.
