Scientists Respond to Stephen Hawking's Bizarre Warning About Trump Turning Earth to Venus

Climate scientists, even those who warn of catastrophe due to manmade climate change, mocked Stephen Hawking's absurd suggestion that by pulling the United States out of the Paris climate accord, President Donald Trump would turn the Earth into the planet Venus.

"We are close to the tipping point where global warming becomes irreversible. Trump's action could push Earth over the brink, to become like Venus, with a temperature of two hundred and fifty degrees, and raining sulphuric acid," Hawking, a renowned cosmologist and author of A Brief History of Time, told BBC News in an interview on Sunday.

"A good example that even brilliant scientists sometimes say silly things when it's outside their field of expertise (see Nobel disease)," tweeted Zeke Hausfather, a climate scientist at U.C. Berkeley who has supported the alarmist position on global warming.

Other scientists proved much harsher. "Stephen Hawking's wacky & bizarre opinions on climate change (e.g. Earth becoming Venus) pollute policy debate," declared Ryan Maue, an atmospheric scientist at the Cato Institute's Center for the Study of Science.

Bjorn Lomborg, director of the Copenhagen Consensus think thank and author of Cool It: The Skeptical Environmentalist's Guide to Global Warming, explained exactly why Hawking's suggestion was silly. "Stephen Hawking being silly: No risk of climate runaway to Venus US Paris cuts were just 0.2% of needed to 2°C," Lomborg tweeted.

Lomborg is correct. The Paris climate accord only aimed to be a first step to keep Earth's climate from rising "out of control," as in by 2 degrees Celsius ... by 2100. Venus does indeed have a temperature of two hundred and fifty degrees, and it does rain sulphuric acid. But Venus is closer to the Sun — much closer. In fact, Venus is 25.72 million miles closer to the Sun than the Earth is.

The idea that carbon emissions could turn Earth into Venus is not just laughable, it's insane. Venus has a much different atmosphere, and is millions of miles closer to the Sun. Even if carbon emissions were proven to be linked to warming temperatures, and even if that rise was truly catastrophic, they would have no chance of turning the Earth into Venus.
