WASHINGTON (AP) — The head of the government agency that monitors climate change says that in nearly two years he has never discussed the issue with President Donald Trump.

Acting National Oceanic and Atmospheric Administration chief Adm. Timothy Gallaudet said in a press conference at a scientific meeting this week, “I personally have not briefed the president on climate change.”

Gallaudet says he doesn’t know if others had briefed the president. He does note that he was in the room when Trump signed a bill aimed at keeping plastic trash out of the ocean.

Trump has dismissed his administration’s warnings about the impact of climate change, including a recent government forecast that it could lead to economic losses of hundreds of billions of dollars a year by the end of the century.
