npub1fh6lat3js6w5qs7dsakddvzecmdfz2np0mmy6zyufvfhac37z5qqayzu76 (npub1fh6…zu76) Sorry to be a pain! MPWP? We are now at 418.51 ppm of atmospheric CO2 (Sept. 2023). The maximum in the KM5c stage of the MPWP was 421 ppm. Solar luminosity was slightly less than now, orbital parameters were the same, paleogeography a bit different. Global warming 3 Celsius. The main difference between then & now is the aerosols in our atmosphere. Clean air legislation will get rid of them. End of the Hansen & Sato (2013) "Faustian bargain" - yes? 3 C global warming - yes? Help!!
