William Jefferson "Bill" Clinton in denial of reality

Bill Clinton, April 13, 2011 (The New York Oberserver):

"Now, there is almost nobody in denial about the reality of climate change,"

Gallup,  March 11, 2011:

"In a sharp turnaround from what Gallup found as recently as three years ago, Americans are now almost evenly split in their views of the cause of increases in the Earth's temperature over the last century."

PRINCETON, NJ -- Gallup's annual update on Americans' attitudes toward the environment shows a public that over the last two years has become less worried about the threat of global warming, less convinced that its effects are already happening, and more likely to believe that scientists themselves are uncertain about its occurrence. In response to one key question, 48% of Americans now believe that the seriousness of global warming is generally exaggerated, up from 41% in 2009 and 31% in 1997, when Gallup first asked the question.

PS
How is it possible that the former president is so ill-informed? Does he not read newspapers ? Does he not have any advisers, who keep him informed?  Or has his economic situation become so bad, that he cannot afford to buy newspapers and keep advisers?

Or could this be another case for Steve Van Aperen?
