On Monday, NYT reporter Andy Revkin and I appeared on EcoTalk, an Air America radio show. The subject was Andy’s now-notorious piece on the "new middle" in the climate debate and the huge uproar it sparked.

You can listen to the show by going here, or directly link to segments one, two, and three. I think it turned out fairly interesting.

One thing I would take issue with is Andy’s insistence that we can’t solve global warming with today’s technology, and that with current technology you "fairly quickly hit a wall" in what you can do.

My response: that wall is a long way off. And by the time we get to where the wall was, it will have moved. The overriding imperative, as I tried to emphasize on the show, is to start moving.
