Recent warming is mostly due to natural climate factors…only 1/3 is attributable to the rising GHG concentrations. CO2’s impact on warming is likely wildly overstated. A recent paper by Ad Huijser, “Global Warming and the ‘impossible’ Radiation Imbalance,” published in Science of Climate Change, presents a detailed analysis that challenges the widely held assumption that rising greenhouse […]

The evidence keeps piling up. Climate sensitivity to an increase in atmospheric CO2 is effectively zero. Scientists Hermann Harde and Michael Schnell published a paper in 2021 entitled “Verification of the Greenhouse Effect in the Laboratory.” The study alleged to experimentally determine the atmospheric CO2 greenhouse effect not only exists, but functions in concert with physical […]

CO2 concentration increases are not the cause of rising temperature, but an effect of rising temperature. An independent researcher (Robbins, 2025) has reviewed recent research that suggests at least “80% or more of the [modern CO2] increase is of natural origin.” This is because “changes in atmospheric temperature are an ‘effect’ of changes in SSTs […]

Not only does CO2 have no discernible effect on climate, but any alleged anthropogenic role within the hypothetical greenhouse effect is not detectable either. In recent decades there has been a concerted effort to assert it is “settled” science to characterize variability in the atmospheric CO2 concentration – assumed to be modulated by human activity […]

“All in all, and contra to the IPCC reports, there is insufficient evidential basis for the use of carbon dioxide, et cetera, emissions – taken together, the IPCC’s Anthro – as climate policy variables.” − Green and Soon, 2025 A new evidence-based study provides compelling evidence that for decades the IPCC has been engaged “advocacy […]

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 […]
