Reconstructions 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 the […]

Highly 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 since […]

Prompted 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 has […]

Something 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 to […]

Clouds 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) during […]

German 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 Nature […]

From 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 and […]

By 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 difference […]

Marine species subjected to high CO2 extremes – 8,891 to 95,000 ppm – in their natural environments may not be adversely affected. They may even “thrive”. Earlier this year we highlighted a study that says coral reefs “thrive” near seafloor volcanic vents where CO2 concentrations reach 60,000 to 95,000 ppm. Image Source: PHYS.ORG Urchins basking in […]

An observational analysis of photometric evidence suggests solar forcing of Earth’s atmosphere could vary by as much as ±4.5 W/m² since 1750, which is “far larger than the IPCC estimate of −0.30 to +0.10 W/m²” (Judge et al., 2020). A 2017 study suggested the solar activity during the “modern maximum period from 1940 to 2015” […]

The radiative impact of CO2 on the ocean’s thermal skin layer cannot penetrate deeper than 0.01 mm. This effectively eliminates the potential for CO2 to be a driver of global warming. According to mainstream anthropogenic global warming (AGW) science, 93% of global warming is manifested in the 0-2000 m oceans. Just 1% of global warming […]

Though it’s believed the 130 ppm increase in atmospheric CO2 concentration since 1750 has caused the ocean waters to “acidify”, on a daily basis 50-380°C metallic acid enriched by CO2 concentrations reaching 60,000 to 95,000 ppm pours through seafloor vents. Nearby coral reefs “thrive” in these high-CO2 conditions. Image Source: PHYS.ORG 50 times more CO2 […]
