From National Journal’s Waning Warming Debate: “According to a survey from ABC News, Planet Green and Stanford University, fewer than half — 47 percent — of Americans consider global warming an important issue to them personally, down from 52 percent in April 2007. Although a vast majority still think the planet is warming — 8 in 10 respondents — that figure is also down from last year, having dropped 4 percentage points. Furthermore, in an open-ended question, the number of respondents who called global warming the biggest environmental challenge facing the world fell 8 points from 2007 and currently hovers at 25 percent.” [If you click on the link, look at who's sponsoring most of the advertising on the National Journal website]
