The global climate talks in November face challenges related to international aid and other issues because of the United States’ withdrawal from the Paris Agreement.

The Trump administration’s withdrawal from the Paris climate agreement will have a “strong impact” on the global pact and the negotiations surrounding it, said the incoming president of this year’s COP30 climate talks in Brazil.

“We negotiated the Paris accord for the U.S. to join,” Brazil’s climate and energy secretary, André Aranha Corrêa do Lago, said Wednesday during a webinar with the Wilson Center. “So the U.S. absence will change many things.”

Corrêa do Lago, a longtime climate diplomat, will helm the United Nations talks in mid-November, where countries are expected to discuss their climate targets for 2035, as called for by the Paris deal — despite nearly every nation having missed the Feb. 10 deadline to submit those plans.
