Professor Stephen Hawking is probably the most famous living scientist, so when he speaks, his words are given a much greater significance than those of less well known scientists. He may be an expert on black holes and cosmic radiation, but how much has he studied climate? Here is his latest pronouncement on the subject of climate change:

His main concern during his latest interview was the future of our species. A particular worry was President Trump's decision to withdraw from the Paris climate agreement to reduce CO2 levels.

"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," he told BBC News.
"Climate change is one of the great dangers we face, and it's one we can prevent if we act now. By denying the evidence for climate change, and pulling out of the Paris Climate Agreement, Donald Trump will cause avoidable environmental damage to our beautiful planet, endangering the natural world, for us and our children."

For such an intelligent man I am surprised that he has so readily bought in to the alarmist meme. As with many such articles it leaves me wishing I could ask him to really justify his pronouncements. How does he know "we are close to a tipping point"? He is allowed to make the claim without any challenge. His other claims are equally bizarre. He gets away with parroting the alarmist lines without any justification. As for Earth becoming like Venus, that is an extraordinary claim that even pro-alarmist climate scientists have not made. He gives not one shred of evidence for it and nor was it challenged. Propaganda, pure and simple. I would really like to see him rebut something like this article, for example. But this he would never do.

I wonder if he has given much serious study of the science. He is just a well known person, like Prince Charles and the Pope who has a following among the public and as many of the public know nothing of the science either they will be likely to take notice of someone that they believe will know more than they do.
