In new research (Liu et al., 2026), scientists acknowledge clouds “markedly impact near-surface air temperatures” by altering the radiation budget and driving heating rates across the Arctic. For example, a cloudy day in winter may deliver 20-30 W/m² of cloud radiative forcing (CRF), warming the Arctic surface by 6-9°C. However, due to massive uncertainties in […]

“Slight warming of the air is also observed with [100,000 ppm] CO2 but is close to the temperature resolution of the sensors with ±0.1°C. Given an approximately 400 times lower CO2 concentration in the atmosphere, this warming is likely negligible.” – Schnell and Harde, 2026 New lab experiment research shows that the addition of 100,000 […]

Today’s climate models are so inaccurate they must be improved a hundredfold just to detect a CO2 signal in climate change. Though clouds “are the largest moderator of Earth’s radiation budget and their absorption of solar radiation directly influence our understanding of climate change,” NASA’s models of the cloud capacity to alter solar radiation diverge […]

The data show flat trends in shortwave radiation, longwave radiation, and radiation balance for the global ocean since 1970 despite a 100 ppm increase in CO2. An unheralded 2025 study uses long-term observed cloud cover data over oceans to uncover trends in radiative fluxes from 1900 to 2020. Trends in the subtropics (15-40°N, 45-65°W) indicate […]

More observational evidence emerges showing CO2’s effects are too small to drive climate. The oft-cited Feldman et al. (2015) paper proposes to isolate the CO2 impact by only considering a “clear-sky” atmosphere at two sites: the North Slope of Alaska and the Southern Great Plains (USA). In other words, that study can only claim to […]

The climate sensitivity to a doubling of CO2 with feedbacks may only be about 1°C, with humans contributing just 30% to the global warming since 1850. New research indicates the climate models that the Intergovernmental Panel on Climate Change (IPCC) rely upon for policy-making – and to claim humans are 100% responsible for the warming […]

Natural changes in cloud albedo, absorbed shortwave forcing (ASW), and solar activity (TSI, total solar irradiance) are “the dominant factors driving climate change.” Dai Ato, an independent researcher from Japan, has completed a comprehensive regression analysis (Ato, 2026) using key climate variables and published the results in the Science of Climate Change journal. Using widely […]

Modern climate science is constructed on a foundation of belief. Svante Arrhenius is known as the “godfather” of the CO2 greenhouse effect. Today’s climate models are still based on his 1896 thought-experiment calculations of CO2’s imagined capacity to warm Earth’s surface (71% water) out of a frozen solid state by tens of degrees. His one-dimensional […]

CO2’s role in climate change is too small to detect in error-ridden attribution measurements. Downward longwave radiation (DWLWR) at the ocean surface “is among the most important components of the heat flux across the ocean-atmosphere interface, which, in turn, shapes the climate state of both the atmosphere and the ocean” (Peng et al., 2025). According […]

“The remaining 98.43% of climate forcing arises from sources other than anthropogenic CO2.” – Davis, 2025 When it comes to climate forcing, “atmospheric CO2 plays a minor and diminishing role in forcing contemporary global warming.” Key quotes from Davis, 2025 “As a result of today’s higher concentrations of CO2 in the atmosphere, the radiative forcing […]

Global warming was significantly more pronounced in the early 20th century and prior to 1940, or back when CO2 emissions rates were 8.6 times lower than they were from 1983-2024. A new study using 60 million daily maximum/minimum temperatures from 1600 global weather stations across 29 countries indicates the globe warmed at a rate of […]

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 […]
