Yale Project on Climate Change Communication: "66 percent of Americans believe global warming is happening (a 3% increase since November 2011), but the proportion who said global warming is caused by human activities decreased from 50 to 46 percent.
While only 14 percent of Americans said they do not believe global warming is happening, respondents incorrectly estimated that 21 percent of Americans do not believe in global warming."
