Hawking slams Trump, warns Earth could become like Venus
British physicist Stephen Hawking in an interview with BBC warned, "We're close to the tipping point where global warming becomes irreversible." Hawking further criticised US President Donald Trump for pulling US out of the Paris Climate Agreement, saying, "Trump's action could push the Earth over the brink, to become like Venus, with a temperature of 250ÂºC and raining sulphuric acid."
