A Watershed Moment for Obama on Climate Change

Ain't eBay grand? For $10 you can buy a sack of 50 assorted Obama '08 buttons, and that's what I've been doing. If you look closely, you might see them this weekend on the lapels of some of the global warming protesters holding a sit-in outside the White House.

Already, more than a thousand people have signed up to be arrested over two weeks beginning Aug. 20 -- the biggest display of civil disobedience in the environmental movement in decades and one of the largest nonviolent direct actions since the World Trade Organization demonstrations in Seattle back before Sept. 11. (Among the first 500 to sign up, the biggest cohort was born in the Truman administration, followed closely by FDR babies and Eisenhower kids. These seniors contradict the stereotype of greedy geezers who care only about their own future.)

The issue is simple: We want the president to block construction of Keystone XL, a pipeline that would carry oil from the tar sands of northern Alberta down to the Gulf of Mexico. We have, not surprisingly, concerns about potential spills and environmental degradation from construction of the pipeline. But those tar sands are also the second-largest pool of carbon in the atmosphere, behind only the oil fields of Saudi Arabia. If we tap into them in a big way, NASA climatologist James Hansen explained in a paper issued this summer, the emissions would mean it's "essentially game over" for the climate. That's why the executive directors of many environmental groups and 20 of the country's leading climate scientists wrote letters asking people to head to Washington for the demonstrations. In scientific terms, it's as close to a no-brainer as you can get.

But in political terms it may turn out to be a defining moment of the Obama years.

That's because, for once, the president will get to make an important call all by himself. He has to sign a certificate of national interest before the border-crossing pipeline can be built. Under the relevant statutes, Congress is not involved, so he doesn't need to stand up to the global-warming deniers calling the shots in the House.

But the president does need to stand up to the fossil fuel industry, which has done its best to influence the decision. Since the State Department plays a role in recommending a decision, the main pipeline company helpfully hired the former national deputy director of Hillary Clinton's 2008 presidential campaign as its lead lobbyist. WikiLeaks documents emerged recently showing U.S. envoys conspiring with the oil industry to win favorable media coverage for tar sands oil. If you were a cynic, you'd say the fix was in.

Still, the final call rests with Barack Obama, who said the night that he clinched the Democratic nomination in June 2008 that his ascension would mark "the moment when the rise of the oceans began to slow and our planet began to heal." Now he gets a chance to prove that he meant it. In basketball terms, he's alone at the top of the key -- will he take the 20-foot jumper or pass the ball? It's a rare, character-defining moment. Obama can't escape it simply by saying that someone else will burn the oil if we don't. Alberta is remote, and its only other possible pipeline route -- to the Pacific and hence Asia -- is tangled in litigation. That's why the province's energy minister told Canada's Globe and Mail last month that without the Keystone pipeline Alberta would be "landlocked in bitumen," the technical name for the heavy, gooey tar that is its chief export. Critics may argue otherwise, but Obama's call is key; without it, that oil will stay in the ground for at least a while longer. Long enough, perhaps, that the planet will come fully to its senses about climate change.

It's hard to predict what will happen. Earlier this summer Al Gore tossed up his hands in despair: "President Obama has never presented to the American people the magnitude of the climate crisis," Gore said. "He has not defended the science against the ongoing withering and dishonest attacks." Yet it's hard to give up on the image of the skinny senator from Illinois and the young people who were his most fervent supporters -- young people who, according to pollsters, wanted a climate bill by a 5-to-1 margin. That didn't happen, of course; for now, the Keystone pipeline is the best proxy we have for real presidential commitment to the global warming fight.

Hence the buttons. Many of us will be wearing them while we sit outside his house, in an effort to show that we're not, exactly, protesting. We're trying to rekindle some of that passion from his groundbreaking campaign. We're trying to remind ourselves and the president how good it felt to be full of hope.
