“[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 […]

“Until now, the origin of the climate dynamics of the Central Andes during the last millennium has been speculative. On the basis of statistical evidence, we have identified solar variability as its origin.” – Schittek et al., 2025 In a new study, scientists have determined: 1) The Little Ice Age (LIA) was a global-scale cold […]

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 […]

Sun, clouds and climate – a post from an EIKE reader Image: NASA (public domain) Posted by AR Göhring In a conversation with the EIKE editorial team, our reader Garik Müller noted that recent solar storms have promoted cloud formation – which would contradict the Svensmark-Shaviv effect and the Forbush effect. But the Earth’s atmosphere […]

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) […]

Yet another scientific study concludes CO2 is an insignificant contributor to Earth’s recent temperature changes. New research involving a comparative analysis of satellite (CERES) observations of absorbed solar radiation (ASR) and CO2 radiative forcing modeling finds CO2 may have contributed just 0.09°C to the 0.52°C temperature increase from 2000 to 2023. The rising ASR trend […]

“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, […]

Jet Stream Blocking and U.S. Heat Wave Index By Kyoji Kimoto In 1962, Japanese meteorologist Hirohide Saito found the instability of summer temperature of Hokkaido (northern part of Japan) during the solar minimum as follows: Fig.1 Instability of summer temperature (white circle) of Hokkaido In 1967 Japanese meteorologist Junkichi Nemoto published the following graph, below, […]

Across Europe there has been a downward trend in cloud and aerosol albedo over the last 40 years, allowing more solar radiation to reach the surface. This “brightening” effect thus explains recent warming. A new study (Wacker et al., 2024) from a “testbed site” in Germany reports total and direct shortwave (SW) radiation forcing rose […]

The warming of the oceans since the turn of the century can easily be explained by the increasing trend in absorbed solar radiation. Earth’s energy imbalance was determined to be +0.6 W/m² during the first decade of the 21st century (Stephens et al., 2012) using satellite observations. However, uncertainty in this positive imbalance value is […]

The warmest 50-year period in northeastern China occurred from 1844-1893. Li et al., 2024 “Compared with single years, in general, high or low temperatures that persist for many years will more significantly affect the growth of trees [30]. When we defined years with T12-1 ≥ −10.73 °C (Mean + 1σ) and T12-1 ≤ −12.61 °C […]

The globe’s cities are warming primarily due to declining albedo, not CO2 radiative forcing. According to a comprehensive new study published in Remote Sensing of Environment, CO2 fertilization has led to an enhanced greening trend in 72.6% of cities across the world since 1985, accelerating to 89.2% since 2001. Per the authors, this greening trend […]
