Cloud cover changes are a “top-down dynamical driver” of Earth’s climate. A July 2026 Environmental Research Letters paper authored by Bellocchi et al. attributes ~80% of the rise in Earth’s absorbed solar radiation since 2000 to declining high-reflectivity cloud cover, primarily from circulation-driven contraction of storm-cloud zones. The study highlights the climate’s “albedo governance,” suggesting […]

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 […]

Radiative forcing imbalances are predominantly elicited by anomalies and trends in surface solar radiation, which is modulated by aerosol and cloud albedo. New research indicates that from 1750 to present there was a total net -10.95 W/m² surface radiative forcing (RF) over South Asia. This negative radiation imbalance – a cooling effect – has been […]

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 […]

“These findings indicate that the primary driver of air temperature increase in Kraków is the rise in SD (solar radiation influx) rather than [CO2] radiative forcing (∆F).” New research shows internal or natural changes in cloud structure have allowed more solar radiation to reach the surface in recent decades as documented by the widespread increase […]

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.” […]
