"We are close to the tipping point where global warming becomes irreversible," the famed theoretical physicist said. "Trump's action could push the Earth over the brink, to become like Venus, with a temperature of two hundred and fifty degrees, and raining sulphuric acid," he told BBC News.
"We have given our planet the disastrous gift of climate change ... When we we have reached similar crises there has usually been somewhere else to colonize ... But there is no new world, no utopia around the corner," he said. "We are running out of space, and the only places to go to are other worlds."
Humans have 100 years to find a new planet, or else become extinct, renowned physicist Stephen Hawking says in an upcoming BBC series.
"I have already completed a zero gravity flight which allowed me to float weightless, but my ultimate ambition is to fly into space," Hawking told host Piers Morgan of "Good Morning Britain" on Monday. "I thought no one would take me but Richard Branson has offered me a seat on Virgin Galactic and I said yes immediately."
Theoretical physicist Stephen Hawking is one of the most intelligent individuals on the planet, which is why his assertion that humanity has only 1,000 years left on Earth and must find another place to colonize is incredibly frightening.
