So, do we know all there is to know about Carbon Dioxide? Bonus question at the end of the post!!! Even within the confines of human knowledge, almost no one knows all that can be known about CO2. It’s simply humanity’s hubris that allows us to believe we do. For instance, this is fairly commonly known …..
C 27.291 %; O 72.708 %
But, what about this? Physical Properties
0.001799 at room temperature/pressure * – 1 atm pressure
Do people know what this is and means?
How about this?
|State of Matter||Enthalpy of Formation||Entropy||Gibbs Free Energy|
|(g)||-94.05 8||-393.51||51.07 8||213.68||-94.26 8||-394.38|

What’s my point? The point is there are many things about CO2 that people don’t readily know or understand. And, yes, that includes people pretending to be climate scientists.
Today, we see this from the Hockey Schtick.
Paper finds lifetime of CO2 in atmosphere is only 5.4 years
A paper presented at the SEVENTEENTH SYMPOSIUM ON THERMOPHYSICAL PROPERTIES finds that the lifetime and residence time of man-made CO2 in the atmosphere are only about 5.4 years, far less than assumed by the IPCC. The paper corroborates prior work by Salby, Humlum et al, Frölicher et al, Cho et al, Calder et al, Francey etl, Ahlbeck, Pettersson, Segalstad, and otherswhich has demonstrated that man-made CO2 is not the primary driver of atmospheric CO2.
Fossil Fuel Emissions and Fossil CO2 in the Atmosphere

The comparison of fossil fuel emissions (6.4 GtC/yr) with the growth rate of atmospheric CO2 (3.2 GtC/yr) suggests that about half of the anthropogenic CO2 has not remained in the atmosphere: it has dissolved in the ocean or has been taken up by the land. The isotope ratio C13/C12 of atmospheric CO2 has been measured over the last decades using mass spectrometry. From these data the fraction of fossil CO2 in atmospheric CO2 is straightforwardly calculated: 5.9 %(1981) and 8.5 %(2002). These results indicate that the amount of past fossil fuel and biogenic CO2 remaining in the atmosphere, though increasing with anthropogenic emissions, did not exceed in 2002 66 GtC, corresponding to a concentration of 31 ppm, that is 3 times less than the CO2 increase (88 ppm, 24 %) which occurred in the last century. This low concentration (31 ppm) of anthropogenic CO2 in the atmosphere is consistent with a lifetime of t(1/2) = 5.4 years, that is the most reliable value among other in the range 2-13 years, obtained with different measurements and methods. Contrary to the above findings on the concentration of fossil CO2 and its residence time in the atmosphere, in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change it is stated that almost 45 % of anthropogenic emissions, corresponding to 88 ppm or 24 % of the total CO2, have remained in the atmosphere with a mean lifetime of t(1/2) = 30.5 years. On these assumptions are based both the theory of Anthropogenic Global Warming and the climate models.
Will this be accepted by the nutters? Of course, not. But, I would point out that the nutters never could adequately account for the atmospheric CO2 concentration. Given their thoughts on the lifetime of CO2 in the atmosphere, they were always missing some. And, it’s never really been agreed on exactly how long this molecule stays in the air. 20, 30, hundreds of years! We’ve seen it all! Well, now we have a better understanding. But, we don’t know jack even about this basic molecule. There’s much much more to know and understand.
