The low duration of CO2 in the atmosphere explains why climate models fail

Around 7 years ago I had a long debate with John Quiggin on this issue (e.g. this and this).

In the meantime many other papers have emerged that confirm very low residence time for CO2 in the atmosphere, e.g.

Scrutinizing the carbon cycle and CO2 residence time in the atmosphere by Hermann Harde (2017) – this paper suggests FOUR YEARS. “The average residence time of CO2 in the atmosphere is found to be 4 years.”

There seem to be (I’ve not personally confirmed) many studies that suggest residence time is WAY LOWER than what IPCC models claim (source: Jennifer Marohasy) – the original source.


Two basic facts explain why CO2 levels are increasing despite such low half-life.
– Warming started WELL BEFORE man made emissions

– CO2 released from oceans INCREASES when temperature increases.

Therefore, natural CO2 emissions likely explain most of the current CO2 levels. And therefore climate models fail.

I can see in this issue how IPCC is TOTALLY DISREGARDING THE FINDINGS OF SCIENTISTS to pick the one that creates most panic.

This paper may also be worth looking at, although I’ve not examined it.
