The survey, by the Pew Research Center for the People & the Press, found a sharp decline over the past year in the portion of Americans who see solid evidence that global temperatures are rising. According to the survey, conducted between Sept. 30 and Oct. 4 among 1,500 adults reached on cell phones and landlines, fewer respondents also see global warming as a very serious problem; 35% say that today, down from 44% in April 2008.

The survey also points to a decline in the proportion of Americans who say global temperatures are rising as a result of human activity. Just 36% say that currently, down from 47% last year.
