Scientists say new climate law is likely to reduce warming

Massive incentives for clean energy in the U.S. law signed Tuesday by President Joe Biden should reduce future global warming “not a lot, but not insignificantly either,” according to a climate scientist who led an independent analysis of the package.

Even with nearly $375 billion in tax credits and other financial enticements for renewable energy in the law, the United States still isn’t doing its share to help the world stay within another few tenths of a degree of warming, a new analysis by Climate Action Tracker says. The group of scientists examines and rates each country’s climate goals and actions. It still rates American action as “insufficient” but hailed some progress.

“This is the biggest thing to happen to the U.S. on climate policy,” said Bill Hare, the Australia-based director of Climate Analytics which puts out the tracker. “When you think back over the last decades, you know, not wanting to be impolite, there’s a lot of talk, but not much action.”
