Three of eight Americans don't believe in science of climate change; debate more cultural than scientific

There is no denying that a strong scientific consensus about the existence of climate change exists, especially since scientists have documented a build-up of greenhouse gases and their findings have been endorsed by a large body of domestic and international scientific agencies. But what doesn't exist in the U.S. is a social consensus about climate change. Studies have shown that Americans' belief in the scientific findings of climate change has mostly declined over the last five years.

Between April 2008 and October 2009, belief in climate science dropped to 57 percent from 71, according to the Pew Research Center. This February, it had risen to 62 percent, which means 38 percent of Americans still do not trust it. "Such a significant number of dissenters tells us that we do not have a set of socially accepted beliefs on climate change," Andrew Hoffman, right, the Holcim Professor of Sustainable Enterprise at the University of Michigan, writes for the Stanford Social Innovation Review. He says the debate is not so much about science as about culture, worldviews and ideology.

"Acceptance of the scientific consensus is now seen as an alignment with liberal views consistent with other 'cultural' issues that divide the country -- abortion, gun control, health care, and evolution," Hoffman writes. This partisan divide on the issue is a recent phenomenon, something that wasn't seen during the 1990s. Hoffman examined "the climate change debate through the lens of the social sciences," because he says "we need to understand the social and psychological processes by which people receive and understand the science of global warming."

He writes there are two "overriding conclusions" about the climate change debate: Climate change is not a "pollution" issue, and it is an existential challenge to our contemporary world views. He outlines three possible ways in which the ideological debate will manifest: the "Optimistic Form," in which "people do not have to change their values at all," the "Pessimistic Form," in which "people fight to protect their values," and the "Consensus-Based Form," in which "a reasoned societal debate, focused on the full scope of technical and social dimensions of the problem and the feasibility and desirability of multiple solutions," are discussed.
