California Gov. Jerry Brown attacked President Donald Trump over what he said was Trump's failure to deal with climate change.
Speaking at climate change talks in New York, Brown also compared Trump's supporters to cave dwellers, according to Politico.
"They're both kind of very similar," Brown said, Politico reported. "You should check out the derivation of 'Trump-ite' and 'troglodyte,' because they both refer to people who dwell in deep, dark caves."
Brown has criticized Trump's position on climate change in the past and has sought to cooperate with other states on the issue.
"President Trump is the null hypothesis, which he's proven," added Brown. "Everything he's doing is stupid and dangerous and silly. I mean, come on, really, calling the North Korean dictator 'Rocket Man'? … He is accelerating the reversal through his own absurdity."
CNN reported that Trump administration officials have avoided discussing the issue of climate change in the wake of devastation from Hurricane Harvey in Texas and Hurricane Irma in Florida.
Scientists have pointed out that 2016 was the third year in a row to set a record for the warmest global temperatures.
"I'll be more than happy to have a longer discussion on another day about climate change, man-made climate change," Mick Mulvaney, director of the White House Office of Management and Budget, told CNN when asked about the impact of climate change.
"What we are focusing on right now is taking care of the folks who survived this disaster who need our immediate help," added Mulvaney. "There's plenty of time later on to have those discussions, and I know we will because climate change is clearly a big topic for the media, but we will continue to focus our attention on the folks who need it right now."
Trump has previously referred to global warming as a "hoax." On June 1, Trump pulled the U.S. out of the Paris Agreement, a global accord on climate change.
White House Press Secretary Sarah Huckabee Sanders told reporters she was unsure whether Trump is reconsidering the Paris deal following the hurricanes.
"I don't think that it's changed over the last several weeks," she added when asked if Trump's opinion on climate change has altered.
Brown alleged that Trump would not be able to ignore climate change and would face increased opposition.
"These other powers are going to gang up on Mr. Trump, and he's going to find out: 'You're fired,'" added Brown, according to Politico.
