Professor Stephen Hawking says President Trump will destroy the earth:
I think Hawking knows as much about climate science as Trump does about theoretical physics - next to nothing.
The same applies to Leonardo DiCaprio, Bill Gates, and Mark Zuckerberg, all of whom have been successful in their primary careers, but who are dilettantes when it comes to science.
I'll be frank - I have no workable solution to any of our problems. But neither do any of these guys. We're not going to escape to Mars, and we'll starve to death long before sulfuric acid rains from our skies.
