Stephen Hawking Flies off the Scientific Reservation

Stephen Hawking

by Roy W. Spencer, Ph. D.

I can understand when pop-scientists like Bill Nye spout scientific silliness.

But complete nonsense coming from Stephen Hawking? Really?

In this video, Stephen Hawking claims that Trump withdrawing the U.S. from the Paris Accord could lead to the Earth being pushed past a tipping point, with Venus-like 250 deg. C temperatures and sulfuric acid rain.

The trouble with this statement is that no reputable climate scientist would claim such a thing. The reason is that Venus has about 220,000 times as much carbon dioxide in its atmosphere as does Earth.

Meanwhile, human civilization will have trouble simply doubling (2x) our atmospheric CO2 concentration (it’s taken about 100 years to increase it by 50%, which is half way to doubling).

Since we don’t know what our future energy mix will be in 50-100 years, it’s not obvious we will even reach “2 X CO2”.

So, how could we possibly get from 2x to 220,000x?

We can’t.


Not even if we wanted to.

Venus is a very different planet. Venus has 93x as much atmosphere as Earth, and it is almost 100% CO2. The CO2 concentration in our comparatively thin atmosphere is only 0.04%.

I have no idea where Hawking ever got such a wild idea. Apparently, he had his audience in tears with his dire predictions.

This is partly why the public makes fun of scientists. Sad.

Why do CO2 lag behind temperature?

71% of the earth is covered by ocean, water is a 1000 times denser than air and the mass of the oceans are 360 times that of the atmosphere, small temperature changes in the oceans doesn’t only modulate air temperature, but it also affect the CO2 level according to Henry’s Law.

The reason it is called “Law” is because it has been “proven”!

“.. scientific laws describe phenomena that the scientific community has found to be provably true ..”

That means, the graph proves CO2 do not control temperature, that again proves (Man Made) Global Warming, now called “Climate Change” due to lack of … Warming is – again – debunked!
