Donald Trump’s victory in the U.S. presidential election has darkened the outlook for a strong deal at the COP29 climate summit next week and will increase pressure on Europe and China to lead international progress in curbing planetary warming,

Trump has called climate change a “hoax,” he pulled the United States out of the 2015 Paris climate accord during his first term and has said he would do so again. He has also pledged to expand oil and gas production, eliminate subsidies for clean energy and electric vehicles, and roll back regulations aimed at reducing planet-warming emissions.

He won support with pledges to solve economic woes. But his fossil-fueled solutions and retreat from international cooperation would worsen the climate crisis.

Instead, they will be guided by a curated team of loyalists with a mission to weaken or eliminate parts of the government. That includes EPA, the Interior Department and NOAA.

Trump’s plans have the potential to send fossil fuel companies’ profits soaring while threatening the world’s climate goals.
