Sean McElwee blames messaging:
According to Dr. Robert Bartlett, chair of the Department of Political Science at the University of Vermont, the problem has been framing. “Environmentalists tend to frame the issue in terms of harm and justice, while conservatives respond to in-group loyalty, sanctity, respect and stewardship.” Aaron Sparks, a Ph.D. student at the University of California, Santa Barbara who is studying the issue with Phillip Ehret, finds that about 20 to 30 percent of strong conservatives hold pro-environment attitudes (meaning they are willing to sacrifice economic growth to protect the environment). But Democrats must be “smart about how they frame their appeal,” Sparks says. “Conservatives can be persuaded to accept the environmental argument if is pitched in a way that is consistent with their morality, which tends to emphasize the sacredness of nature and a focus on local, community-building issues.”
But a 2012 study finds that climate campaigns overwhelming continue to frame the issue as harm and care, fairness and oppression of marginalized groups.
