"To understand how quickly President Trump's energy and climate team has turned over since his inauguration, one meeting held about a year ago offers some perspective.
Organized by then-White House energy adviser Mike Catanzaro, the meeting on June 21, 2017, convened top aides from across the administration. The subject was "Climate policy meeting." It followed weeks of questioning by reporters about Trump's views on global warming.
The president had just announced, three weeks earlier, that the United States would exit the Paris climate accord, and his administration was working to dismantle carbon dioxide regulations for power plants. In the White House briefing room, Trump's press secretary declined to say whether the president accepted that climate change was happening."
