On the same day of his inauguration, President Trump on Monday issued an executive order to withdraw the U.S. from the United Nations Paris Agreement, the global pact to address climate change by mitigating greenhouse gas emissions. Iran, Libya and Yemen are the only three other countries not party to the agreement. The withdrawal will become official one year after the submission of a letter of notification to the United Nations.

The United States is the world’s top historical emitter of greenhouse gas emissions, and by withdrawing from the agreement, Trump is once again ignoring the increasing evidence of the threat climate change poses in favor of promoting fossil fuels. Trump withdrew from the Agreement at the beginning of his first term in 2017, only for Biden to rejoin in 2021.

“President Trump is choosing to begin his term pandering to the fossil fuel industry and its allies,” the Union of Concerned Scientists said in a statement. “His disgraceful and destructive decision is an ominous harbinger of what people in the United States should expect from him and his anti-science cabinet.”
