Acceptance of Global Warming Among Americans Reaches Highest Level Since 2008

October 2015

For the first time since 2008 at least 7 out of 10 Americans indicate that they believe there is solid evidence of global warming over the past four decades. This 70% belief level is the second highest mark in the history of the National Surveys on Energy and the Environment (NSEE) falling just short of the 72% record level reported in Fall 2008. This increased level of acceptance of evidence of global warming coincides with the lowest percentage of Americans expressing doubt in solid evidence of global warming in the history of the NSEE. The Fall 2015 survey shows that only 16% of adult Americans currently believe there is not solid evidence of global warming, a mark 1% lower than the previous record of 17% recorded in Fall 2008.
