They really did it. The Inflation Reduction Act, which is mainly a climate change bill with a side helping of health reform, passed the Senate on Sunday; by all accounts it will easily pass the House, so it's about to become law.
This is a very big deal. The act isn't, by itself, enough to avert climate disaster. But it's a huge step in the right direction, and sets the stage for more action in the years ahead. It will catalyze progress in green technology; its economic benefits will make passing additional legislation easier; it gives the United States the credibility it needs to lead a global effort to limit greenhouse gas emissions.
There are, of course, cynics eager to denigrate the achievement.
