Even if the entirety of the modern CO2 concentration increase is due to human activity, the impact (pressure) on global temperatures amounts to no more than 15-18%. In a new study, geology professor Dr. Wojciech Stankowski has summarized some of the reasons why the prevailing narrative that says humans can drive climate change by burning […]

“An increase in low cloud cover of only about 1% could largely compensate for the doubling of CO2.” – van Wijngaarden & Happer, 2025 Ph.D physicists detail just how insignificant CO2 is as a factor in climate change, revealing that doubling the CO2 concentration from 400 ppm to 800 ppm – a 100% increase – […]

The 2013-2022 warming trend and the extreme warmth in 2023 were “not associated with” declining outgoing longwave radiation induced by rising greenhouse gases. Instead, a new study published in the journal Science contends that decreasing cloud albedo and the consequent increase in ASR, or absorbed solar radiation (+0.97 to 1.10 W/m²/decade according to ERA5 and […]

The evidence that rising CO2 concentrations lead to inconsequential warming keeps piling up. In a new study, seven Viennese researchers provide more evidence the CO2 absorption band is already saturated at today’s concentrations (over 400 ppm). Rising CO2 levels thus cannot drive significant global warming. “Data from ground measurements indicate that the downward (backward) radiation […]

A new analysis indicates tripling the atmospheric CO2 concentration from 100 to 400 ppm only produces a 0.3°C surface warming effect. Eight engineers (Wei et al., 2024) from the National Sun Yat-Sen University in Taiwan have assessed the capacity of rising CO2 concentrations to affect surface air temperature (SAT) over a 5-year research observation period. […]

Cost-benefit analyses affirm it would be better to abandon Net Zero policy initiatives and instead “do nothing” about greenhouse gas emissions. New research finds CO2’s largest possible climate impact is “negligible.” The cumulative expected temperature change in doubling CO2 from 400 to 800 ppm is only 0.81°C at most, and this is “certainly not cause […]

“[T]he contribution of CO2 to the greenhouse effect is 4% – 5%. Human CO2 emissions represent 4% of the total, which means that the total human contribution to the enhancement of the greenhouse effect is 0.16% to 0.20% – a negligible effect.” – Dr. Demetris Koutsoyiannis (2024) New research exposes the vacuousness of the “imaginary […]

“The heat retention in the greenhouse Earth is caused by all gas components…mainly by nitrogen and oxygen. It is not permissible to exclusively assign the GH effect of 33° to water vapour, CO2, and the other trace gases.” – Ullmann and Bülow, 2024 Chemical physicists Helmut Ullmann and Martin Bülow have published a new paper […]

Yet another scientific study concludes CO2 is an insignificant contributor to Earth’s recent temperature changes. New research involving a comparative analysis of satellite (CERES) observations of absorbed solar radiation (ASR) and CO2 radiative forcing modeling finds CO2 may have contributed just 0.09°C to the 0.52°C temperature increase from 2000 to 2023. The rising ASR trend […]

Climate models failed to simulate the observed 1970-2014 Pacific Ocean cooling. The 21st century southwestern US megadrought has been linked to this cooling, which “may have been caused by a forced response to greenhouse gas emissions.” A new study provides a fresh look at the circular, self-contradictory reasoning that proponents of the anthropogenic global warming […]

To claim that anthropogenic CO2 emissions drive global warming, radiative forcing modeling studies must assume 1) clouds do not ever change, 2) cloud albedo is constant, and/or 3) clouds do not exist. None of these are real-world conditions. The real atmosphere is what scientists refer to as all-sky, an atmosphere where clouds not only exist […]

“Our analysis revealed that the observed decrease of planetary albedo along with reported variations of the Total Solar Irradiance (TSI) explain 100% of the global warming trend and 83% of the GSAT interannual variability as documented by six satellite- and ground-based monitoring systems over the past 24 years.” – Nikolov and Zeller, 2024 A new, […]
