Physics Prof. Concludes Doubling CO2 Adds Just 0.5°C; ‘Cannot Affect Climate’
earth and sunA new CO2 climate sensitivity study suggests that beyond the 300 ppm threshold, “any further increase of (anthropogenic) CO2 cannot lead to an appreciably stronger absorption of radiation, and consequently cannot affect the earth’s climate.”
Dr. Schildknecht is a Bielefeld University physics professor affiliated with the Max Planck Institute in Munich.
His equilibrium climate sensitivity estimate (0.5 or 0.6°C for a doubling of CO2 from 380 to 760 ppm) is identical to many other recent estimates (Stallinga et al., 2020, Ollila, 2019, Smirnov, 2017, Smirnov, 2020, Harde, 2016, Bates, 2016, Kissin, 2015, Abbot and Marohasy, 2017, Gervais, 2016).
