Now, he has joined the global warning bandwagon. He warns that if we “don't curb irreversible climate change,” Earth could turn into a hot planet like Venus.
However, even Michael Mann, a climate scientist at the Pennsylvania State University, does not agree with Hawking.
Mann sent Live Science an email, saying:
"Hawking is taking some rhetorical license here Earth is further away from the sun than Venus and likely cannot experience a runaway greenhouse effect in the same sense as Venus — i.e. a literal boiling away of the oceans.”
Speculations nearly always get noticed, regardless of how little facts (if any) there are to give substance to them.
