Global warming versus climate change

Science Daily: Many Americans are skeptical about whether the world's weather is changing, but apparently the degree of skepticism varies systematically depending on what that change is called. According to a University of Michigan study published in the forthcoming issue of Public Opinion Quarterly, more people believe in "climate change" than in "global warming."

"Wording matters," said Jonathon Schuldt, the lead author of the article about the study and a doctoral candidate in the U-M Department of Psychology.

Schuldt co-authored the study with U-M psychologists Sara Konrath and Norbert Schwarz. For the research, they conducted a question wording experiment in the American Life Panel, an online survey conducted by RAND, with a national sample of 2,267 U.S. adults. Participants were asked to report their level of certainty about whether global climate change is a serious problem. In the following question, half the participants heard one version, half heard the other:

"You may have heard about the idea that the world's temperature may have been going up [changing] over the past 100 years, a phenomenon sometimes called 'global warming' ['climate change']. What is your personal opinion regarding whether or not this has been happening?

Overall, 74 percent of people thought the problem was real when it was referred to as climate change, while about 68 percent thought it was real when it was referred to as global warming….
