When Will Global Warming Reach a Political Tipping Point?

Presidential candidates traditionally blow off the environment as an issue. But can they continue to dither as the world heats up?

"What should be the nation's top concern?" When pollsters pose such a question to voters, few, historically, have answered "the environment." Yet when asked specifically about how important global warming will be to their vote for U.S. president in 2008, more than half of respondents to a CNN/Opinion Research Corporation poll last May answered "extremely" or "very." To learn how the quadrennial mash-up of politics and the environment will play out this election year, Sierra turned to four expert observers:

Matt Stoller is a Washington, D.C.-based political consultant and blogger who writes frequently for Open Left, MyDD, and the Huffington Post. He's worked for the campaigns of (successful) New Jersey gubernatorial candidate Jon Corzine (D) and (unsuccessful) Connecticut senatorial candidate Ned Lamont (D).

Michael Bocian is a vice president at Greenberg Quinlan Rosner Research, a D.C.-based polling and strategic consulting firm. He heads the company's environmental and conservation practice.

David Orr teaches environmental studies at Oberlin College and is the author of five books, including Earth in Mind and Ecological Literacy.

Newt Gingrich was the speaker of the U.S. House of Representatives from 1994 to '98 and architect of the Contract With America -- an effort criticized by the Sierra Club and other environmental groups. More recently, Gingrich has written (with Terry L. Maple) A Contract With the Earth, a plea for bipartisan environmentalism, and is chair of the nonpartisan organization American Solutions for Winning the Future.

Sierra senior editor Paul Rauber orchestrated the conversation by e-mail last October.

Q: How will global warming figure in the 2008 presidential election?

Newt Gingrich: Whoever wins will have a sound and realistic approach to climate change. Democrats have an advantage in developing solutions because their primary voters care more about the issue and because they are more comfortable dealing with environmental issues, which have been largely a liberal area of dialogue for the past generation. Republicans have to play catch-up in developing answers other than no.

Our research at American Solutions indicates that, by a very substantial margin, Americans prefer entrepreneurship to bureaucracy and innovation to litigation. The Republican nominee should be able to develop strong solutions to climate change that emphasize science, technology, innovation, and incentives. These will prove surprisingly popular compared with the tax increase-government control-bureaucracy and litigation model that has dominated for the past 30 years.

Michael Bocian: Mr. Gingrich is correct that the public clamors for innovation. Our polling shows that Americans feel our country is failing to lead on energy and global-warming solutions, yet they believe we have the technological know-how to lead, and we must harness it. Mr. Gingrich is also correct on the importance of incentives. But any purely voluntary solution fails to address the seriousness of the problem. Americans believe we need strong standards if we are to succeed. Setting strong standards and enforcing them require real accountability.

David Orr: The Republican Party has not done its homework on the biggest issue of our time and has persistently chosen ideology over science, even going along with the Bush administration's crude attempts to quash the evidence. The time to avert the worst is very short. To do so, we will have to create something akin to the government-business-public partnership in WWII. This will necessarily include lots of things Mr. Gingrich has opposed in the past: government regulation, taxation to change market incentives, and lots of R&D on renewables and efficiency. It will also require attention and money -- so no more wars fought for phony reasons.
