Sixty-nine percent of Republicans surveyed in a Gallup poll released Wednesday said they think the seriousness of global warming is exaggerated, up from 66 percent a year ago.

That compares with only 4 percent of Democrats who think concerns are exaggerated, down from 10 percent in 2017.

Other key measures of climate change opinions showed similarly growing partisanship, Gallup said.

Among Republicans, only 42 percent said that most scientists think global warming is occurring, 11 percentage points lower than last year. Democrats’ opinions on that question are the same as last year, with 86 percent agreeing.
