A new Gallup survey shows a stark partisan divide in Americans’ beliefs on global warming. About one-third of the public — mostly Democrats — say they worry “a great deal” about global warming, while a much larger number, mostly Republicans and independents, say they worry about warming “only a little” or “not at all” or “a fair amount.”

At the same time, a solid majority of Americans express great concern about a number of other environmental issues. It’s just global warming that doesn’t bother them much.
