Using the guy’s own data from the excerpt puts the lie to his entire premise.
15*C is less than 25% of 66*C
288*C is 85% of 336*C
He claims 17.6% is the same as 15%.
Fraud and charlatan. No better than the liars promoting CAGW/climate change. “Close enough” isn’t.
No, the author is spot on.
You have to do the comparison in absolute temperature (Kelvin), and not relative temperature (degree C).
If you want, I can send you some additional links to explain.
Dude...I think the guy is full of it, but at least he’s not trying to calculate percentages of temperatures in Centigrade. Jeez.
