United Nations climate talks collapse after Trump shuns Paris pact

MADRID — U.N. climate negotiations ended in disarray on Sunday, amid worries that President Donald Trump will win reelection next year and follow through on his promises to withdraw the U.S. from the international effort to head off catastrophic changes across the planet.

The talks exposed deep rifts among industrialized nations, fast-growing economies like China and India and the poorest countries – divides that the U.S. had helped bridge under former President Barack Obama in the run-up to the 2015 Paris climate accord. With Trump moving to pull out of the pact, delegates from many countries retreated behind their long-held grievances over how to bear the burdens of reducing greenhouse gases and preparing for the worsening effects of a changing climate.
