Share this…FacebookTwitterIn 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 […]

Share this…FacebookTwitterUsing NASA’s MERRA-2 radiation data, scientists find shortwave radiation (SW) has been rising since the 1980s. The SW increase has been larger and faster than longwave radiation (LW) changes during this same timespan. Cloud variability has been the “main driver” of these trends.

Share this…FacebookTwitterIn 2019, more than 440 scientific papers were published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…or that otherwise serve to question the efficacy of climate models or the related “consensus” positions commonly endorsed by policymakers and mainstream media sources. Image Source: Collins et al., […]

Share this…FacebookTwitterCO2 concentrations rose from 345 ppm to 398 ppm in the 29 years from 1985 to 2014. Mainstream scientists sympathetic to the anthropogenic global warming (AGW) paradigm have nonetheless reported the overall greenhouse effect forcing has been flat to declining throughout this period. 1. Cess and Udelhofen, 2003 Due to the downward trend in […]

Share this…FacebookTwitterThe last 40 years of global temperature changes can be radiatively explained by a natural reduction in cloud cover. From 1979 to 2011, satellite data provide documentation of a reduction in cloud cover and aerosol depth that allowed an additional 2.3 W/m² of positive shortwave energy to be absorbed by the Earth’s surface rather […]

Share this…FacebookTwitterGreenland’s ice sheet mass losses have significantly decelerated since 2013 – a reversal from the rapid retreat from the 1990s to 2012 driven by cloud forcing and the NAO (Ruan et al., 2019). The post-2013 “relatively stable” ice sheet even gained mass during 2017-’18 (Andersen et al., 2019). Ruan et al., 2019 Decelerated […]

Share this…FacebookTwitterNASA has conceded that climate models lack the precision required to make climate projections due to the inability to accurately model clouds. Clouds have the capacity to dramatically influence climate changes in both radiative longwave (the “greenhouse effect”) and shortwave. Cloud cover domination in longwave radiation In the longwave, clouds thoroughly dwarf the CO2 […]

Share this…FacebookTwitterTwo 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 […]
