Over the past decade, Americans have clustered into three broad groups on global warming. The largest, currently describing 39% of U.S. adults, are what can be termed “Concerned Believers” — those who attribute global warming to human actions and are worried about it. This is followed by the “Mixed Middle,” at 36%. And one in four Americans — the “Cool Skeptics” — are not worried about global warming much or at all.
The “Cool Skeptics” always seem to have trouble during recessions, but they are consistently making up ground on the other two groupings. It now seems that it is becoming a two horse race between the “Cool Skeptics” and the “Concerned Believers”.
