Paul Krugman: It’s Easy Being Green

So, have you enjoyed the debate over health care reform? Have you been impressed by the civility of the discussion and the intellectual honesty of reform opponents?

If so, you’ll love the next big debate: the fight over climate change.

The House has already passed a fairly strong cap-and-trade climate bill, the Waxman-Markey act, which if it becomes law would eventually lead to sharp reductions in greenhouse gas emissions. But on climate change, as on health care, the sticking point will be the Senate. And the usual suspects are doing their best to prevent action.

Some of them still claim that there’s no such thing as global warming, or at least that the evidence isn’t yet conclusive. But that argument is wearing thin — as thin as the Arctic pack ice, which has now diminished to the point that shipping companies are opening up new routes through the formerly impassable seas north of Siberia.
