Trump ready to withdraw US from Paris climate agreement, reports say

• Trump tweets that he will announce decision at 3pm ET on Thursday
• Withdrawal would sorely weaken landmark deal by nearly 200 countries
• Frustrated world leaders prepare to move on without the US

Donald Trump is poised to withdraw from the Paris climate accord, according to multiple reports, in a move that would profoundly undermine the landmark agreement by nearly 200 countries to curtail global warming.

Trump tweeted late on Wednesday that he would announce his final decision at 3pm ET on Thursday in the White House rose garden. It followed a wave of reports that he was about to exit from the deal. The reports follow his refusal to express support for global efforts to combat climate change at a G7 summit with European leaders last week.
