Perhaps more than people in any other rich nation, Americans are skeptical that climate change is a dire issue. In Pew Research Center surveys conducted last spring, 40 percent of Americans said that global climate change was a major threat to their country. More than 50 percent of Canadians, Australians, French and Germans gave that answer. More than 60 percent of Italians and Spaniards did. And more than 70 percent of Japanese did.
A scientific report issued Tuesday on the effects of climate change in the United States concluded, “Climate change, once considered an issue for a distant future, has moved firmly into the present.”
