According to a recent presentation by climate scientist Dr. Ole Humlum published in Science of Climate Change: Real-world observations show both cooling and warming trends in the Arctic, Antarctic, and Tropical oceans since ARGO monitoring was introduced in 2004. Real-world observations show no trend in global precipitation since 1979. Real-world observations show global cloud cover […]

Natural atmospheric circulation patterns (like the Western Tibetan Vortex, or WTV) drive total cloud cover (TCC) change, which, in turn modulate the the amount of downward solar radiation reaching the surface. Over southwest Asia, or the Tibetan Plateau, scientists (Wang et al., 2026) indicate the satellite-observed increase in downward shortwave (DSW) “is the primary driver” […]

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 […]

Warming across Germany in the last 3 decades can be explained by declining cloud and aerosol albedo and consequent rising solar radiation. Not CO2. Another new study affirms clouds and aerosols play a key role in explaining trends in solar surface radiation (SSR), which is “essential for the global energy cycle driving the climate system.” […]

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 […]

Another observational analysis finds the shortwave effect of clouds is the “the dominant term of the recent increase in absorbed solar radiation” explaining 2001-2024 warming. According to the authors of a new study, clouds are the primary modulators of the Earth’s shortwave and longwave radiation. Thus, the radiative effects of clouds “play a crucial role […]

“[T]he increase in absorbed solar radiation is primarily due to natural variations in cloudiness and surface albedo, which have served as the main forcing factors of the flux above the atmosphere over the last 2 decades.” – Diodato et al., 2025 It is commonly accepted that there has been a satellite-observed (CERES) cloud cover albedo […]

Because the current state-of-the-art general circulation models (GCMs) cannot simulate the trends and variances in global precipitation over the last 84 years (1940-2023), their usefulness should be reconsidered. Hydrological processes – ocean circulation, water vapor, clouds – are key components of climate, easily overshadowing the impact of anthropogenic CO2 emissions by a factor of 2,100 […]

More cloudy days forecast for 2050… in sync with the AMO… nothing to do with CO2 Hat-tip: Klimanachrichten In a recent paper published in Nature here, German researchers Horst-Joachim Lüdecke, Gisela-Müller Plath and Sebastian Lüning analyzed changes in sunshine duration by using modern statistical methods for a total of seven monthly time series of sunshine […]

“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 […]
