He was cited by someone he (and you) disagree[s] with, but he leans into statistical regression pretty heavily. It might be of interest. |
1) One consideration: Anthropogenic Greenhouse Gases are not limited to carbon-dioxide.
2) As of November, 2019, Anthropogenic Greenhouse Gases constituted 500-ppmv - carbon-dioxide-'equivalency', with
CO2 @ 410.27 ppmv
and CH4 Methane plus N2O Nitrous-oxide @ 89.73 ppmv CO2-e
--------------------------------------------------------------------------------------
3) It took over 1,000-years for the atmosphere to reach 496-ppm, from 280 ppm without humans.
4) Presently, we've gone from 280- to- 500 in under 100-years.
5) During the last 5-major extinction events, at no time did Earth's greenhouse concentration increase at the rate currently observed. By an order of magnitude.
