My update on Mauna Loa CO2 through 2022 using a simple CO2 budget model.

Tomer Tamarkin says.

"The net amount of equilibrated carbon dioxide (CO2) in the atmosphere is the same as if human beings never existed."

The Pinataubo Study

Dr. Spencer replies:

That study, IMO, comes to bogus conclusions. The decrease in CO2 after the Pinatubo Eruption was, in their view, evidence that nature immediately removes large source of CO2... but nowhere do they justify the assumption that Mt. Pinatubo produced all that CO2 that was supposedly absorbed. Vulcanologists have calculated Pinatubo released the equivalent of only 1 day's worth (!) of anthropogenic emissions. The post-Pinatubo decrease in atmospheric CO2 has been (as I stated) due to increased photosynthesis due to diffuse sunlight penetrating deeper into vegetation canopies. Besides, if Pinatubo really did produce a large amount of CO2, why was there NO evidence of an atmospheric increase afterwards? It makes zero sense.

Dr. Tamarkin replies:

Dr. Spencer,: Our study DOES NOT come to "bogus conclusions." You have stated this previously in other forums. I have attempted to correct you.

And our study has nothing to do with the release of CO2 due to volcanic activity. Again please see: https:// pinatubostudy.co m/ Thank you.
