German physicists claim to have experimentally demonstrated the greenhouse effect from greenhouse gases like CO2 and CH4 is a real phenomenon, but assess the climate sensitivity to a doubling of CO2 with feedbacks is “only ECS = 0.7°C … 5.4x lower than the mean value of CMIP6 with ECS = 3.78°C.” “The derived forcing for […]

Solution: Increase Ocean Evaporation (<4% of CO2 Reduction Cost) Guest poet by David R. Motes, November 10, 2022 Climate change is real and cycles over Earth’s geologic history. We are in a global warming trend for the past 140+ years. Contrary to prevailing climate theory, this man-made warming trend is primarily driven by a CO2 […]

Annual carbon dioxide (CO2) and methane (CH4) change rates lag behind changes in sea ice extent by 7 months and 5 months, respectively. This robust correlation is consistent with the conclusion that CO2 (and CH4) changes are responsive to temperature, not the other way around. It is commonly believed that the annual “squiggle” of the […]

“The cause of global warming is still under debate.” – Choi and Manousiouthakis, 2022 Radiative models estimating the temperature effects of increasing CO2 to 420 ppm indicate 0.64°C of the alleged 1.2°C warming since the 19th century could be explained by CO2 increases. Image Source: Choi and Manousiouthakis, 2022 A 2013 study suggested only 0.26°C […]

Another new study indicates the assumption CO2’s climate impact is not overshadowed by the water vapor impact (because they do not overlap spectrally) is inconsistent with NASA and HITRAN observations. Smirnov, 2022 “Changes in the Earth’s atmosphere that affect its energetics are analyzed. The results of NASA programs on carbon dioxide monitoring in the atmosphere […]

Animal rights activist group PETA is now calling on women to strike on sex with meat-eating men. PETA’s Elena Waldman really can’t stand men having a good time at the weekend barbecue. She writes: “We all know them, the suburban men with beer bottles in hand, brandishing tongs while cooking sausages on their expensive gas […]

A late 2021 study finds water vapor and temperature changes accounted for 90% of the changes in clear-sky downwelling longwave or greenhouse effect forcing since the mid-1980s. CO2 forcing assumed a mere bit-player role. The seminal Feldman et al. (2015) study concluded it takes 10 years and a 22 ppm increase in CO2 to account […]

Scientists have once again affirmed the 2000-2020 total greenhouse effect (longwave) forcing has been declining in recent decades just as absorbed solar radiation has been increasing due to cloud albedo modulation. The latter explains the net positive Earth Energy Imbalance (EEI) and consequent global warming during this period. Recently we detailed the satellite-observed decline in […]

Early Venus is suggested to have been much colder – and thus habitable – due to higher concentrations of CO2…because CO2 drives cooling in most of the Venus atmosphere (stratosphere, mesosphere, thermosphere). Scientists have for decades agreed it is “well recognized” that CO2 molecules radiatively cool the atmospheres of planets like Earth, Mars, and Venus […]

Cloud modulation of shortwave radiation and greenhouse effect forcing has largely been the determining factor in the global warming of the last 45 years. Not CO2. CO2 forcing and its effect on surface temperatures is detailed in analyses of changes in clear-sky radiation only because all-sky radiation effects that include clouds (and the real-world atmosphere […]

CO2 and water vapor greenhouse effect impacts are not independent climate forcings . A new study affirms the “variance in the radiance in these channels is primarily controlled by…temperature” and “atmospheric absorption is strongly saturated in these [CO2, water vapor] channels”. It has previously been established that greenhouse gas (water vapor, CO2) forcing “cannot be […]

Professor Herman Harde, an environmental physicist, has authored a new position paper on the follies of assuming humans significantly impact the climate. As detailed in his 2017 paper, Dr. Harde concludes the “anthropogenic contribution to the actual CO2 concentration is found to be 4.3% [a figure derived from IPCC AR5], its fraction to the CO2 […]
