Share this…FacebookTwitterA new balloon experiment (inadvertently) demonstrates just how weak and inconsequential CO2’s warming effect is. Levendis et al. (2020) tried using an experiment with air-filled (99% nitrogen and oxygen) versus CO2-filled (100% CO2) balloons to demonstrate a consequential warming effect for CO2. But their study may have demonstrated the opposite. In the experiment a […]

Share this…FacebookTwitterScientists report they must “exclude atmospheric pCO2 as a direct driver of SST variations” after finding the Atlantic Ocean’s surface was multiple degrees warmer than today from 90 to 20 thousand years ago, or when CO2 concentrations hovered below 200 ppm. Another new study (Hou et al., 2020) casts even more doubt on the […]

Share this…FacebookTwitterA new analysis by Drs. Wijngaarden and Happer (2020) suggests the “self-interference” saturation of all greenhouse gases in the current atmosphere substantially reduces their climate forcing power. At the current concentrations, the forcing power for greenhouse gases like CO2 (~400 ppm) and CH4 (1.8 ppm) are already saturated. Therefore, even doubling the current greenhouse […]

Scientists (Wang et al., 2020) have determined stomatal evidence can uncover large short-term CO2 fluxes of 50-100 ppm within a century or less. Measurements from a forest near Mt. Kurikoma, Japan, reveal minimum to […]

Share this…FacebookTwitterReconstructions of past temperatures show much colder periods with higher CO2 levels or as-warm or warmer periods with much lower CO2 levels. A new study (Paus, 2020) indicates modern July temperatures center around 7.5 to 8°C in the Scandes Mountains (Norway). Today’s CO2 atmospheric concentration has reached 410 ppm. During the latter stages of […]

Share this…FacebookTwitterHighly anomalous terrain (an active volcano), 40 years of cooling temperatures, and a CO2 record that dramatically contrasts with fluctuating values from forests and meadows reaching 600-900 ppm all beg the question: Is Mauna Loa’s CO2 record globally representative? Mauna Loa is the Earth’s largest land volcano. It has erupted over 3 dozen times […]

Share this…FacebookTwitterPrompted by the observation that dramatic COVID-related reductions in 2020 human CO2 emissions had zero impact on the Earth’s CO2 concentration, two scientists conduct extensive statistical probability analyses to conclude temperature changes lead CO2 changes, not the other way around. The nearly global acceptance of economically-devastating lockdowns as a mitigating response to the COVID-19 pandemic […]

Share this…FacebookTwitterSomething is rotten with the GHE By Erich Schaffer Introduction The greenhouse effect (GHE) is a well established theory which most people consider a solid fact, even those who are otherwise “critical” over global warming. On the other side there are some voices who “deny” the GHE with flatearther-like arguments, which seemingly only adds […]

Share this…FacebookTwitterClouds dominate as the driver of changes in the Earth’s radiation budget and climate. A comprehensive new analysis suggests we’re so uncertain about cloud processes and how they affect climate we can’t even quantify our uncertainty. According to scientists (Song et al., 2016), the total net forcing for Earth’s oceanic atmospheric greenhouse effect (Gaa) […]

Share this…FacebookTwitterGerman climatologist Professor Dr. Horst-Joachim Lüdecke recently took data from two independent studies and superimposed them. The result shows the long claimed atmospheric CO2-global temperature correlation doesn’t exist. The first data set was global temperature anomaly going back 600 million years, taken from the results of a paper by Came and Veizer, appearing in […]

Share this…FacebookTwitterFrom about 80,000 to 20,000 years ago, Greenland temperatures abruptly warmed by about 10°C in just a few decades on at least 20 occasions. And then, about 870 to 1,500 years later, CO2 rose. Li and Born (2019) document 8-16°C climate warmings (Dansgaard-Oeschger events) in Greenland that extended to both hemispheres between about 80 […]

Share this…FacebookTwitterBy Prof. Fritz Vahrenholt at Die kalte Sonne (Translated by P. Gosselin) June 7, 2020 Dear ladies and gentlemen First, the global mean temperature of satellite based measurements was surprisingly much higher in May 2020 than in April. In contrast, the global temperatures of the series of measurements on land and sea decreased. The […]
