"Here's what Gallup found: The number of Americans who say the media have exaggerated global warming jumped to a record 41 percent in 2009, up from 35 percent a year ago. ... What's more, fewer Americans believe the effects of global warming have started to occur: 53 percent see signs of a hotter planet, down from 61 percent in 2008. Global warming placed last among eight environmental concerns Gallup asked respondents to rank, with water pollution landing the top spot.
... More importantly, said Ebell, the planet's average temperature hasn't risen since 1997, despite a 5 percent gain in the amount of atmospheric carbon dioxide in the same period. Twelve years doesn't make for a long-term trend, Ebell said, but every year that goes by with no increase in average temperatures makes it harder to assert the climate is sensitive to carbon dioxide. "I think there's a huge amount of skepticism among the public. They've heard all these claims, and now they've been informed that there isn't any recent warming," Ebell said. "The public, without having a lot of information about it, is pretty astute."
