With all due respect, I don’t think that’s how it works.
If I have ice at 0C and raise its temperature 100%, that would be 1.00 X 0C + 0C = 0C?
But if I go by total thermal energy above absolute zero, then I get a more rational 1.00 X 273.15 + 273.15 = 546.3K = 273.15C. = 491F.
You can’t multiply (percent is multiplication) heat in Celsius without dealing with the 273.15K that is 0C. Ice water is quite hot in Kelvin.
the wording of the article is misleading and inaccurate:
” Even if we burn all the world’s recoverable fossil fuels it will still only result in a temperature rise of less than 1.2 per cent.”
It’s not a rise of 1.2 per cent, it’s a rise of 1.2 degrees.
Thus:
12° Celsius = 53.6° Fahrenheit
12° + 1.2° = 13.2°
13.2° Celsius = 55.76° Fahrenheit
and that would be the impact on the average global temperature after burning up “the total quantity of recoverable oil, gas and coal on the planet.”
So it’s easy to see why Doiron thinks Hansen is such an embarrassingly insufferable twit and his climate mumbo jumbo is so boneheaded.
