Growing number of Americans believe in warming — poll

A larger percentage of Americans now say there is evidence for climate change than at any point in the last decade, according to a new report.

Researchers from the National Surveys on Energy and Environment found that 73 percent of Americans believe there is “solid evidence” for climate change, the most since the biannual poll began in 2008.

Sixty percent think humans are responsible, at least in part, for global temperature rise.

The poll surveyed 751 respondents by phone in April and May, with a margin of error of 4 percentage points.

The survey was conducted, in part, as a major heat wave hit most of the United States. This May was the hottest on record, according to NOAA, though it was preceded by the coldest April in more than two decades.

Still, there remains a wide partisan gap in the way Americans view global warming, the survey found.

The results suggest that 90 percent of Democrats and 50 percent of Republicans see evidence of climate change. The 40-percentage-point margin is tied for the widest partisan divide in the survey’s history.

“The role of party affiliation in determining American views on the existence and causes of global warming has been one of the most salient findings of NSEE studies over the past decade,” the report says. “The divide between Democrats, Republicans and independents in regards to multiple aspects of global warming has been significant over the past decade and the most recent findings indicate this divide is large and modestly widening.”
