Trump quits the Paris climate accord, denouncing it as a violation of U.S. sovereignty - LA Times

The U.S. will pull out of the Paris accord on global warming, President Trump plans to announce, relinquishing the country's leadership role in the international fight against climate change.

The move will not fully take effect for four years, under the terms of the agreement, but is likely to invite diplomatic and economic retaliation from around the world.

The agreement is a "bad deal" for the U.S., the administration says in talking points distributed to supporters.

The agreement, which almost every country in the world has joined, is designed to cut emissions of carbon dioxide and other greenhouse gases in order to keep temperatures from rising by more than 2 degrees Celsius compared with pre-industrial levels. That's the point at which climate scientists warn the impact of climate change worldwide would be severe.

How much the U.S. leaving the accord will impede achieving that goal remains to be seen. Technological and economic changes have steadily made solar and wind power less expensive, and the U.S. was already on a path to meet many of the commitments made in Paris, amid the boom in electricity from natural gas and the plunge in prices for solar and wind power.

But the departure of the world's biggest economy is certain to disrupt international plans to combat global warming. The U.S. will now join the only two other nations that refused to sign on, Syria and Nicaragua. The Central American nation complained that the accord wasn't stringent enough.

The move may also harm the growing U.S. clean-energy industry, which may now see China and Europe take the lead in developing advanced technologies.

President Obama, who helped rally almost every nation in the world to reach the Paris agreement in 2015 had hailed it as one of his signature accomplishments.

But Trump had pledged during his campaign to scrap the agreement, calling it a bad deal for the U.S.

Outside economists have said the cost to the U.S. of staying in the accord would have been minimal, as it allowed flexibility to adjust targets. Keeping the treaty intact would not have prevented the administration from rolling back some of Obama's ambitious domestic climate programs, they said.

But some conservatives warned that environmental activists could use the agreement as a way to block the administration from its efforts to dismantle Obama's policies.
