It was a good idea that didn’t catch on in 2007. Now we’re running out of time.

Back in 2007, I wrote a column calling for a “Green New Deal,” and I later expanded on the idea in a book, “Hot, Flat and Crowded.” Barack Obama picked up the theme and made a Green New Deal part of his 2008 platform, but the idea just never took off. So I’m excited that the new Democratic Congresswoman Alexandria Ocasio-Cortez and others have put forward their own takes on a Green New Deal, and it’s now getting some real attention.

There is no agreed-upon policy road map for a Green New Deal. But as one of the leading climate bloggers, Joe Romm, recently pointed out, “Since the midterms, dozens of U.S. representatives and at least four Democratic senators have pledged support to create a Select Committee to create legislation for a Green New Deal.
