A ‘Nearly Zero’ Climate Sensitivity Paper Finds A 16-Fold CO2 Increase Cools Earth Below Pre-Industrial Temperatures
By Kenneth Richard on 5. March 2020
In yet another new paper (Drotos et al., 2020), scientists determine the climate sensitivity to CO2 is “practically zero” the more the concentration rises. A ~4450 ppm CO2 concentration has cooler climates than observed in the pre-industrial (278 ppm) era. Why? A self-amplifying cloud feedback mechanism cools the Earth by magnitudes “as large as 10 […]
