CO2 in the atmosphere has a residence time of only four years .
However the climate change fantasists at the IPCC now claim that the earth can distinguish between man produced emissions of CO2 and those CO2 produced naturally and that the former last for hundreds of years .
As their climate change apocalypse claims fail to come true the IPCC assumptions are becoming weirder and weirder.
Per a new study, the Intergovernmental Panel on Climate Change (IPCC) utilizes “inappropriate assumption and speculation,” as well as non-real-world models of “imaginary data,” to claim CO2 emissions derived from fossil fuel burning function “weirdly,” far differently in the atmosphere than CO2 molecules derived from natural emissions (e.g., plant respiration, ocean outgassing) do. “The ambiguity is accompanied by inappropriate assumptions and speculations, the weirdest of which is that the behavior of the CO2 in the atmosphere depends on its origin and that CO2 emitted by anthropogenic fossil fuel combustion has higher residence time than when naturally emitted.”
While the IPCC acknowledges emissions from natural sources have an atmospheric residence time of only 4 years, they have simultaneously constructed model outputs that assert CO2 molecules derived from fossil fuel emissions remain in the atmosphere for hundreds, thousands, tens of thousands, even several one hundred thousands of years.
Per the IPCC: “15 to 40% of an emitted CO2 pulse [from anthropogenic emissions] will remain in the atmosphere longer than 1000 years, 10 to 25% will remain about ten thousand years, and the rest will be removed over several hundred thousand years.”
“Carbon dioxide (CO2) is an extreme example, its turnover time is only about 4 years because of the rapid exchange between the atmosphere and the ocean.”
Again, a four-year residence time for natural CO2, but hundreds of thousands of years residence time for CO2 molecules elicited from fossil fuel burning.
It would seem just about any result can be derived from imaginary data.
Nevertheless there are some like Greta, Guterres , Biden and Flannery who still think the IPCC have credibility.
