What it all boils down to is: The bills are coming due. And not just, or even mainly, the bills from a failed Bush presidency, but the bills from 200 years of burning fossil fuel. Twenty years agowhen we started worrying about global warming, we thought we'd have a generation to pay those bills off. But we were wrong — the planet was more finely balanced than we'd realized. The melting Arctic is the call from the repo man.

Any hope of succeeding will require Obama to grasp, deep in his guts, the fact that climate, energy, food, and the economy are now hopelessly intertwined, and that trying to solve any one of these problems without taking on the others simply makes all of them worse....

....The political reality goes like this: George W. Bush was so terrible on this issue that the bar has been set incredibly low — Obama will get all the political points he needs with fairly minimal effort. Doing what actually needs to be done will be politically…unpopular isn't even the word. It might well wreck his political future, because it would involve — directly or indirectly — raising the cost of continuing to live as we do right now.
