Physicists: Clouds ‘Practically Control’ Climate, Whereas Human Warming Amounts To 0.01°C Per 100 Years

By Kenneth Richard on 11. July 2019
 
Two University of Turku (Finland) physicists have determined a) the climate’s sensitivity to a doubling of CO2 is 0.24°C, b) the human contribution to the warming of the past century is only about 0.01°C, c) the IPCC and climate modeling dramatically overestimate CO2’s climate impact, and d) variations in low cloud cover control the climate.

Cloud cover changes “explain the linear trend of global temperature” since the 1980s

In a new paper, O.M. Povrovsky of the Russian State Hydrometeorological University analyzes satellite-observed cloud cover changes during 1983-2009 and their relation to global temperature change.

Povrovsky found global and regional cloudiness decreased between 2-6% during these decades, and “the correlation coefficient between the global cloud series on the one hand and the global air and ocean surface temperature series on the other hand reaches values (–0.84) — (–0.86).”
