From Watts Up With That we get the latest internal inconsistency of the climate panic-mongers.

Including gas, oil and coal, they [the UN’s IPCC] estimate a total fossil fuel reserve of nine hundred to two thousand gigatonnes of carbon (GtC).  I decided to apply those numbers to both the Bern Model and the simple exponential decay model.

Willis Eschenbach, the author of the linked-to article, asked:

My interest was in finding out what would happen, according to the two CO2 models, if we burned all of the fossil fuels by 2100.

That is, if we completely exhausted all of our coal, oil, and natural gas in an orgy of consumption over the next 85 years, what would we get?

Using the two models cited, the Bern model and the simple single-time-constant exponential model, two of the IPCC’s favorite models, Eschenbach got the answer [emphasis his]:

According to the IPCC, there is not enough fossil fuel carbon (oil, gas, and coal) on the planet to double the atmospheric CO2 concentration from its current value.

Doubling the amount of atmospheric CO2 is one of the big bugaboos of the climatistas, never minding that at 800 parts per million by volume of CO2 in the air (the result of that doubling) is just about the level when life on earth was especially lush during earlier geologic eras.

Hmm….
