President Donald Trump's decision to withdraw the United States from the Paris Agreement could set the Earth on the path to be as hot as Venus, physicist Stephen Hawking has said.
"We are close to the tipping point where global warming becomes irreversible," Hawking told the BBC, in an interview published Sunday. "Trump's action could push the Earth over the brink, to become like Venus, with a temperature of 250 degrees, and raining sulphuric acid."
Hawking is no stranger to wading into politics, commenting earlier this year that he, a disabled, politically liberal person from outside the United States, was unsure he was welcome in Trump's America.
"Climate change is one of the great dangers we face, and it's one we can prevent if we act now. By denying the evidence for climate change, and pulling out of the Paris Climate Agreement, Donald Trump will cause avoidable environmental damage to our beautiful planet," Hawking told the outlet.
Late last year, Hawking said humanity would probably need to colonize space in order to survive.
"I fear evolution has inbuilt greed and aggression to the human genome… The best hope for the survival of the human race might be independent colonies in space," Hawking reiterated to the BBC.
