EPA and global warming alarmists use reports from NOAA’s atmospheric CO2 observatory which is located on Mauna Loa. “The Mauna Loa data are being obtained at an altitude of 3400 m in the northern subtropics, and may not be the same as the globally averaged CO2 concentration at the surface. “ https://www.esrl.noaa.gov/gmd/ccgg/trends/ Atmospheric concentrations of CO2 are not consistent globally. Sampling CO2 on the side of a volcano is a problem, but the problem is meaningless compared to the global warming/climate change fraud.
Yes, volcanoes emit large amounts of CO2, but the amount is small compared to emissions from oceans and land. Volcanic activity is the only way that CO2 is returned to the atmosphere once the CO2 has been turned into limestone/CaCO3, which of course results from the continuous natural degradation of all biological material that enters the oceans. Sedimentation of that degraded organic matter plates out in layers which eventually become stone on the bottom of all oceans. That stone is the ultimate carbon sink. The high heat of a volcano or deep earth magma is required in the reaction to release the CO2 from CaCO3. CO2 in the atmosphere is the only pathway for carbon to enter the food chain. Most CO2 re-enters the atmosphere from the oceans. Of course, carbon is the building block for all biology.
That is the carbon cycle simply put. Leave it to arrogant, hubristic so-called “progressives” to break that carbon cycle. Meanwhile they sue, berate and threaten people who call them on their fraud, in addition to funneling billions of dollars of taxpayer and unwitting donor money into crony projects.
Volcanic CO2 is not a major contributor to total atmospheric CO2 concentration. Nor are humans a major contributor to atmospheric CO2 concentration, only about 3.4%.
There are many unanswerd scientific problems which falsify the global warming hypothesis, as you know. Most significantly, the atmosphere cannot significantly warm the oceans because of the huge difference in heat capacity, and the logarithmic/non-linear physical chemistry of CO2 energy absorption and emission. Doubling of CO2 concentration results in progressively diminishing amounts of warming. CO2’s IR quanta are already almost filled at 400 ppm.
To scare people, they present a graphic CO2 steadily rising from 200 ppmv to 400ppmv and sound alarms to extort money. But 200 ppmv is barely enough to keep plants alive.
Lawyers could make many millions and stop this fraud by filing triple damage cases against climate alarmists who are promoting the perhaps unintended consequence of killing the planet … or more likely … the radical reduction in human population under the disproven eugenics theories of Thomas Malthus, Paul “Population Bomb” Ehrlich, John Holdren and Margaret Sanger…now joined by Charles, soon to be King of England.
More than you wanted or expected as usual, and most you already know, but you may want to forward it.
