The Trump administration announced that it will begin formally withdrawing the US from the Paris climate accord, the first step in a year-long process to leave the landmark agreement to reduce emissions of planet-warming gases.
Critics of the withdrawal say that the US leaving an agreement it helped negotiate will harm the country's standing internationally.
A poll conducted by the Yale Program on Climate Change Communication earlier this year showed that about 7 in 10 Americans think global warming is happening, and at least 6 in 10 are "somewhat worried" about it.
