Business Leaders Slam Trump's Decision to Withdraw From Paris Climate Agreement Elon Musk, Mark Cuban and Mark Zuckerberg are among those who spoke out.

President Donald Trump announced Thursday that he will pull the U.S. out of the Paris climate agreement.

The agreement, which was signed by 195 nations in December 2015, aims to slow down the rate at which the planet is warming.

Before today's decision was made, several executives of U.S. companies showed their disapproval of the U.S. pulling out of the agreement. On Wednesday, a letter signed by the executives of major companies, including Facebook, Google, Apple and Unilever, urged the president not to abandon the agreement.

After Trump announced his decision, Tesla and SpaceX CEO Elon Musk said that he will be leaving Trump's advisory council. Other executives have taken to social media to voice their concern.
