So says Gallup, anyway:

I think you could divide this table into two parts: the top five, which concern more than 70 percent of Amerricans, are “things that could kill my child now.” The bottom four are “things that could harm my child, or maybe my grandchildren, later.”

Americans find it harder to be concerned about the latter group, even if global warming in particular poses a tremendous threat. But this is one reason it’s difficult to persuade people to act on climate change now: unlike the American health-care system or the war in Iraq or even poisoned drinking water, it’s not obviously killing anyone right now. Increasingly, I’m becoming convinced that the best hope for policies to combat climate change will come through some sort of alliance with deficit hawks.
