New Accounting For Atmospheric CO2? New Study!


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 …..

Molar Mass:
44.0095 g

Mass Percent:
C 27.291 %; O 72.708 %

But, what about this?  Physical Properties

Density (g/cm3):
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
kcal/mol kJ/mol cal/(mol×K) J/(mol×K) kcal/mol kJ/mol
(g) -94.05 8 -393.51 51.07 8 213.68 -94.26 8 -394.38
(aq undissoc) -98.90 8 -413.80 28.1 8 117.57 -92.26 8 -386.02

State of Matter Specific Heat
cal/(mol°C) J/(mol°C)
(g) 8
(aq undissoc) 8

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
Luciano Lepori S, Gian Carlo Bussolino, Andrea Spanedda and Enrico Matteoli C
IPCF-CNR, Pisa, Italy
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.

BONUS QUESTION:  What is carbonic anhydride? No fair using a search engine!!!

    LOVE THIS POST!!!!!!!!!!!!!!!!!

    Carbon and water?

  3. Latitude says:

    actually the residence time of any CO2 is…………………zero

  4. cdquarles says:

    Carbon dioxide. Carbonic acid without the water :).

  5. cdquarles says:

    The residence time of carbon dioxide will be determined by its rate of formation from chemical reactions that release it and out-gassing from sources not made by chemical reactions (chemical reactions include buffering reactions) and by the rate of removal from chemical reactions that destroy it or precipitate it out of buffers. The solvation reaction is not a typical chemical reaction in that the species do not change from one to another, but that reaction can add or remove energy from a system.

    The National Hurricane Center says the Butterflies in West Africa are frantically breeding and we can expect an above normal Hurricane season, Any day now, just you wait and see!

    “And, yes, that includes people pretending to be climate scientists”

    who would find kindred spirits with sociologists, palm readers and realtors.

  8. Bruce says:

    Carbonic anhydride is almost as dangerous as hydroxylic acid.

    When I was a climatology student three decades ago, we were taught that CO2 hang time was on average seven years. I definitely smelled a rat the first time I saw the modeled assumptions from the alarmists.

    • suyts says:

      No doubt, and then they kept telling us the hang time was longer and longer….. gazillions of years!!!

    • not even 7 years – CO2 is washed by the next rain into the sea or the soil;
      that’s why plants are more prosperous from 2 inches of rain, than from equal amount of flood irigation

      • gator69 says:

        I conducted my first CO2 soybean experiment in 1977, and have said ever since that we need more CO2 in the atmosphere, and not less.

        Carbonic acid is responsible for one of my early love affairs, spelunking.

        • by inventing how to make fire artificially, human created the present desert and released the biggest amount of CO2 – good for the crops. More CO2 was released by rubbing two sticks than five industrial revolutions would do.

          the good Lord made water to wash things – CO2 doesn’t stay in the atmosphere for more than few weeks – get washed by every rain. cheers!

  10. when the truth is irrelevant; CO2 is the new evil devil
