New Study: Recent 'Unprecedented' Cloud Cover Decline Driving Modern (And Past) Climate Change

New Study: Recent ‘Unprecedented’ Cloud Cover Decline Driving Modern (And Past) Climate Change

“[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 […]

New Study: Today's Climate Models 'Do Not Agree With Reality' And Thus Their Usefulness Is 'Doubtful'

New Study: Today’s Climate Models ‘Do Not Agree With Reality’ And Thus Their Usefulness Is ‘Doubtful’

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 […]

NATURE Study: Sunshine Hours, Cloud Cover In Europe Follow Atlantic Cycles, Not CO2

NATURE Study: Sunshine Hours, Cloud Cover In Europe Follow Atlantic Cycles, Not CO2

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 […]

Physicists: Increasing CO2 By 100% Only Reduces Radiative Cooling To Space By An Imperceptible 1%

Physicists: Increasing CO2 By 100% Only Reduces Radiative Cooling To Space By An Imperceptible 1%

“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 – […]

New Study: The Warming Trend Since 2013 Explained By Increases In Absorbed Solar Radiation, Not CO2

New Study: The Warming Trend Since 2013 Explained By Increases In Absorbed Solar Radiation, Not CO2

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 […]

New Study: Cloud Changes 'Are The Cause Of Changes In The Accumulated Solar Energy'

New Study: Cloud Changes ‘Are The Cause Of Changes In The Accumulated Solar Energy’

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 […]

The Recent Decades Of Cloud Cover Decline May Be A Continuation Of A Trend That Began In 1818

The Recent Decades Of Cloud Cover Decline May Be A Continuation Of A Trend That Began In 1818

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) […]

Studies That 'Confirm' Humans Cause Climate Rely On Imaginary-World Conditions In Their Calculations

Studies That ‘Confirm’ Humans Cause Climate Rely On Imaginary-World Conditions In Their Calculations

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 […]

Satellite Observations Confirm 2000-'22 Warming Has Been Due To An Increasing Solar Radiation Trend

Satellite Observations Confirm 2000-’22 Warming Has Been Due To An Increasing Solar Radiation Trend

“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 […]

Scientists: 100% Of 2000-2023 Warming Explained By Solar Forcing...Human Climate Forcing 'Does Not Exist In Reality'

Scientists: 100% Of 2000-2023 Warming Explained By Solar Forcing…Human Climate Forcing ‘Does Not Exist In Reality’

“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, […]

New Study: 1979-2013 Southern Ocean And Southeast Pacific Cooling Driven By...Warming?

New Study: 1979-2013 Southern Ocean And Southeast Pacific Cooling Driven By…Warming?

Scientists attempt to explain why approximately one-third of the global ocean’s sea surface temperatures cooled since the late 1970s. The 50-70°S Southern Ocean and 160°W to 80°W southeastern Pacific cooled by about -0.35°C (-0.117°C per decade) from 1979-2013 (Yao et al., 2024). (The cooling also continued to 2019, but the authors chose to use 2013 […]

Scientists Admit Cloud Radiative Properties Are 3D But Studies 'Ignore' This And Use 1D Simulation Data

Scientists Admit Cloud Radiative Properties Are 3D But Studies ‘Ignore’ This And Use 1D Simulation Data

Modeling the main factors driving climate is riddled with and precluded by observational error. Some scientists now acknowledge this. Clouds are a main factor – even the “most important factor” – controlling changes in the Earth’s radiation budget, or climate (Sfîcă et al., 2021, Lenaerts et al., 2020). Image Source: Sfîcă et al., 2021 and […]
