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.” This is action, he said. Not as much as Europe, and Americans still spew twice as much heat-trapping gases per person as Europeans, Hare said. The U.S. has also put more heat-trapping gas into the air over time than any other nation. Before the law, Climate Action Tracker calculated that if every other nation made efforts similar to those of the U.S., it would lead to a world with catastrophic warming — 5.4 to 7.2 degrees (3 to 4 degrees Celsius) above pre-industrial times. Now in the best case scenario, which Hare said is reasonable and likely, U.S. actions, if mimicked, would lead to only 3.6 degrees (2 degrees Celsius) of warming. If things don’t work quite as optimistically as Hare thinks, it would be 5.4 degrees (3 degrees Celsius) of warming, the analysis said. Even that best case scenario falls short of the overarching internationally accepted goal of limiting warming to 2.7 degrees warming (1.5 degrees Celsius) since pre-industrial times. And the world has already warmed 2 degrees (1.1 degrees Celsius) since the mid-19th century. Other nations “who we know have been holding back on coming forward with more ambitious policies and targets” are now more likely to take action in a “significant spillover effect globally,” Hare said. He said officials from Chile and a few Southeast Asian countries, which he would not name, told him this summer that they were waiting for U.S. action first. And China “won’t say this out loud, but I think will see the U.S. move as something they need to match,” Hare said. Scientists at the Climate Action Tracker calculated that without any other new climate policies, U.S. carbon dioxide emissions in 2030 will shrink to 26% to 42% below 2005 levels, which is still short of the country’s goal of cutting emissions in half. Analysts at the think tank Rhodium Group calculated pollution cuts of 31% to 44% from the new law. Other analysts and scientists said the Climate Action Tracker numbers makes sense. “The contributions from the U.S. to greenhouse gas emissions are huge,” said Princeton University climate scientist Gabriel Vecchi. “So reducing that is definitely going to have a global impact.” Samantha Gross, director of climate and energy at the Brookings Institution, called the new law a down payment on U.S. emission reductions. “Now that this is done, the U.S. can celebrate a little, then focus on implementation and what needs to happen next,” Gross said. ___ Follow AP’s climate and environment coverage at https://apnews.com/hub/climate-and-environment ___ Follow Seth Borenstein on Twitter at @borenbears ___ Associated Press climate and environmental coverage receives support from several private foundations.
