CO2: "WHY ME?"
ON WHY CO2 IS KNOWN
NOT TO HAVE ACCUMULATED IN THE ATMOSPHERE &
WHAT IS HAPPENING WITH CO2 IN THE MODERN ERA
by Jeffrey A. Glassman, PhD
Myles Goodman at Drexel posted the following question as a comment to the Acquittal of Carbon Dioxide:
You posit that CO2 does NOT accumulate in the atmosphere. How do you explain atmospheric concentrations of CO2 increasing over the last 100 years?
The Acquittal shows that carbon dioxide did not accumulate in the atmosphere during the paleo era of the Vostok ice cores. If it had, the fit of the complement of the solubility curve might have been improved by the addition of a constant. It was not. And because the CO2 presumably still follows the complement of the solubility curve, it should be increasing during the modern era of global warming in recovery from Earth's various ice epochs. These conclusions find support in a number of points in the IPCC reports.
So the answer to the post begins with supporting background on why CO2 is known not to accumulate in the atmosphere, and then goes on to other aspects of the model that global warming causes increases in CO2, which accounts for the last 100 years or so.
