New Haven, Conn. — A growing number of Americans consider global warming an important threat that calls for drastic action, and 40% say that a presidential candidate’s position on the issue will strongly influence how they vote, according to a national survey conducted by Yale University, Gallup and the ClearVision Institute.

“One of the most surprising findings was the growing sense of urgency,” said Anthony Leiserowitz, director of the Yale Project on Climate Change and the study’s principal investigator. “Nearly half of Americans now believe that global warming is either already having dangerous impacts on people around the world or will in the next 10 years—a 20-percentage-point increase since 2004. These results indicate a sea change in public opinion.”

The survey was conducted July 23-26, 2007, using telephone interviews with 1,011 adults, aged 18-plus. Respondents came from Gallup’s household panel, which was originally recruited through random selection methods. The final sample is consideredto be representative of U.S. adults nationwide, with a margin of error of ±4 percentage points. Survey results are available online: http://environment.yale.edu/news/5305-american-opinions-on-global-warming/.

The Yale Project on Climate Change at the Yale School of Forestry & Environmental Studies supports public discourse and engagement with climate-change solutions.
