WASHINGTON, March 19 (Reuters) - Twenty-one states led by Democratic-governed New York and California joined by 14 cities and counties sued President Donald Trump's administration on Thursday seeking to undo its decision to revoke the government's scientific finding that underpins U.S. climate regulations, the New York Attorney General's Office said.

The legal challenge filed against the Environmental Protection Agency in the U.S. Court of Appeals for the District of Columbia takes aim at the agency's move last month to terminate the government's 2009 conclusion that climate change endangers human health and the environment. Trump has called climate change a hoax.
