Wild fires, and especially volcanoes.......
About two weeks ago there was a huge wildfire in Alberta Canada and the smoke carried all the way to S.E. Michigan and in sufficient amount to make the totally cloudless sky hazy.......
I’m halfway through the paper. It’s easy reading for a first take. If what he says is true, the IPCC model is incredibly flawed. I can understand “compartmentalization” of different parts of the CO2, such as in the ocean, or in shellfish, or minerals, versus that in the atmosphere. But, along with the author, I can’t see any justification for treating CO2 differently depending on whether it was “naturally” or “anthromorphically” generated. That’s like a chemical bill of attainder.
Also, its very interesting that a simple exponential model (what he calls “e-time” engineers call “time constant”) accounts better for 14CO2 decay from nuclear weapons tests better than the IPCC model.
If what he says is true, how can the IPCC model creators have been so dumb? Overfitting a model violates Occam’s Razor, and usually doesn’t work out well.
Finally, to your second comment, about wild fires and volcanoes... is there any reason to believe they’re worse over the past century than they were before? Or was there a dip in CO2 due to a fire/volcano quiet period in the late 18th century?
