Climate scientists and policy experts are criticizing famed theoretical physicist Stephen Hawking for arguing President Donald Trump’s policies would push the Earth “over the brink” towards runaway global warming.
Hawking told told BBC News in a Sunday story that Trump’s recent decision to withdraw the U.S. from the Paris climate accord would doom the Earth.
“We are close to the tipping point where global warming becomes irreversible. 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,” Hawking said in the interview....
...Climate scientists, even those usually worried about future global warming, pushed back against Hawking’s claims that Earth would become like Venus.
Meteorologist Ryan Maue called Hawking’s statements “bizarre,” and professor and environmental activist Bjorn Lomborg noted how the Paris agreement would only avert 0.2 degrees of projected global warming.

Stephen Hawking being silly:
No risk of climate runaway to Venus
US Paris cuts were just 0.2% of needed to 2°Chttps://twitter.com/hausfath/status/881602869237084161 …

Venus’s atmosphere is 96.5 percent carbon dioxide, which means its climate is extremely hot compared to Earth’s climate. Earth’s atmosphere is only four-hundredths of one percent carbon dioxide...
...Despite the stark differences between Earth and Venus, the United Nations’ top environmental official was happy to push Hawking’s warning that the end was nigh because Trump wanted to leave the Paris agreement.
