New Atmospheric Sciences Textbook: Climate Sensitivity Just 0.4°C For CO2 Doubling

CO2 Contribution: 0.15°C Since 1959  – Dr. B. Smirnov, Microphysics of Atmospheric Phenomena Purveyors of the viewpoint that rising CO2 emissions pose a grave threat to the planet via dangerous global-scale warming presuppose that the surface temperatures of the Earth are highly sensitive to parts per million (ppm) variations in atmospheric CO2 concentrations. And yet the accumulation of […]

Recent CO2 Climate Sensitivity Estimates Continue Trending Towards Zero

Recent CO2 Climate Sensitivity Estimates Continue Trending Towards Zero

Updated: The Shrinking CO2 Climate Sensitivity A recently highlighted paper published by atmospheric scientists Scafetta et al., (2017) featured a graph (above) documenting post-2000 trends in the published estimates of the Earth’s climate sensitivity to a doubling of CO2 concentrations (from 280 parts per million to 560 ppm). The trajectory for the published estimates of transient climate response […]
