The United States would remain a party to the United Nations Framework Convention on Climate Change<br />and could still participate in future U. N.-sponsored climate discussions.<br />Meanwhile, a core part of the Paris deal involved the United States promising $3 billion in aid to poorer countries to help them expand clean energy<br />and adapt to droughts, sea-level rise, and other global warming calamities.<br />President Trump said on Thursday that the United States was officially withdrawing from the Paris climate agreement, following through on a campaign promise<br />and defying fellow world leaders who had pleaded with him to remain a party to the pact.<br />But Mr. Trump said he would not abide by any of the United States’ previous commitments under the Paris agreement<br />and would rejoin only if the accord were drastically renegotiated, an unlikely prospect.<br />The big question now is how other countries will respond to Mr. Trump’s withdrawal: Do they keep pressing<br />ahead with climate action anyway, or does the accord start to unravel without the United States?
