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