According to a recent poll conducted in the United States, Americans continue to express less concern about global warming than they have in the past.

51% of Americans say they worry about the problem, when three years ago the figure was as high as 66%.

The findings are part of Gallup’s annual environment poll, which has shown that:

-80% of Americans claim they understand the issue more than ever.

-43 % think the seriousness is generally exaggerated as opposed to 26% who think it is generally reported as corrected.

-the economic downturn may be of influence as environmental concerns tend to take a back seat to economic matters when the economy is in a bad shape.

The poll is based upon a random selection of 1,021 adults.
