Stephen Hawking Suggests Deniers Of Climate Change Visit Venus For A Lesson On Greenhouse Gases

Kristine Moore

Stephen Hawking has just issued a clear and stark warning to climate change deniers: amend your beliefs or Earth may end up like Venus. Don't believe him? He's offering to pay the fare for a voyage to Venus to observe just how greenhouse gases can wreak havoc on a planet.

"Next time you meet a climate-change denier, tell them to take a trip to Venus; I will pay the fare."
"Venus is like Earth in so many ways, a sort of kissing cousin. She's almost the same size as Earth, a touch closer to the sun. She has an atmosphere."

To gain a better understanding of how this is possible, it's worth remembering that Venus wasn't always the planet it currently is, and for its first 2 billion years of existence, it may very well have had temperatures that would have easily permitted even humans to have lived on it, as Michael Way of NASA highlighted.

"Many of the same tools we use to model climate change on Earth can be adapted to study climates on other planets, both past and present. These results show ancient Venus may have been a very different place than it is today."

"This is what happens when greenhouse gases are out of control."
"We are close to the tipping point where global warming becomes irreversible."
