Trump’s day-one actions on energy come as climate change-fueled fires ravage Southern California, following the globe’s hottest year on record.

President Donald Trump will once again withdraw the United States from the Paris climate deal, the White House said on Monday, removing the world's biggest historic emitter from global efforts to fight climate change for the second time in a decade.

WASHINGTON (Reuters) - President Donald Trump will order the U.S. to withdraw from the Paris climate agreement, the White House said on Monday, once again placing the world's top historic emitter of greenhouse gas emissions outside of the global pact aimed at pushing nations to tackle climate change through domestic actions.

President Donald Trump says he will again withdraw the United States from the landmark Paris climate agreement.

America is the world's second-largest greenhouse gas polluter - and it will no longer be part of global efforts to limit climate change through the landmark Paris Agreement.

President Trump announced Monday that he would be pulling the United States from the Paris Climate Accord shortly after being sworn into office.

Under the U.N. rules at the time, the U.S. withdrawal took three years to take effect, allowing former President Joe Biden to swiftly reinstate American participation in the accords. This time, however, the U.S. could completely quit the Paris Agreement in just one year.

Quitting the Paris Agreement triggers a cascade of real-world impacts and signals the beginning of an aggressive agenda to undo U.S. climate policy.
