President Trump has been threatening to pull the United States out of the Paris Climate Accord for months. But the latest reports from the White House suggest that decision could come soon. A U.S. withdrawal would be a devastating blow to the planet and the clearest signal yet that Trump is abandoning our nation’s leadership in the fight against catastrophic climate change. There will be diplomatic consequences as well. Just last week, the leaders of all G7 countries reaffirmed their commitments to the Paris deal—all except the United States, that is. Trump's decision would also not sit well with most Americans. A recent study found that 70 percent of Americans support staying in the international agreement. U.S. businesses have also been speaking out in support of the Paris accord. Twenty major companies, including Microsoft, Apple, and Hewlett Packard, recently sent an open letter to Trump stating, “We believe the United States can best exercise global leadership and advance U.S. interests by remaining a full partner in this vital global effort.” Even the oil giant Exxon Mobil and at least one other U.S. oil company want to stay in. We'll soon learn who the president listens to: Americans, U.S. businesses, international partners, and even some oil companies, or the few fossil fuel polluters who threaten the well-being of us all.
