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 […]

The radiation budget changes shaping trends in global dimming (cooling) and global brightening (warming) are driven by cloud cover changes, which are themselves modulated by internal deep ocean processes. A new study assesses the associated factors in North Atlantic climate variations, noting how critical clouds are in modulating Earth’s Energy Imbalance (EEI). “Cloudiness is the […]

Per a new study, the last 200 years of global warming are associated with cloud cover decline, and this decreasing cloud albedo can be linked to “the dominant roles of external forces – volcanic, solar, and oceanic – in their mutual influence after the LIA [Little Ice Age].” Scientists have repeatedly reported a satellite-observed (CERES) […]

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 […]

“Earth’s energy imbalance has doubled from 0.5 ± 0.2 W/m² during the first 10 years of this century to 1.0 ± 0.2 W/m² during the past decade. The increase is the result of a 0.9 ± 0.3 W/m² increase absorbed solar radiation (ASR)…” − Loeb et al., 2024 Satellite observations from CERES (Clouds and the […]

“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, […]
