Yet another observational study determines changes in Earth’s reflectiveness, or planetary albedo, may be primarily responsible for 21st century climate forcing. Earth’s radiation budget at the top of atmosphere (TOA) is predominantly controlled by internal changes in cloud cover. A declining albedo – linked to declining cloud cover – corresponds to an increase in the […]

Of the warming trends in Poland and greater Europe, “only about 4–5% are explained by an increase in CO2 concentration.” – Marsz et al., 2022 Internal changes to the thermal structure of the ocean transmit decadal-scale changes in the atmospheric circulation and consequent surface air temperature via its modulating impact on the variation in the […]

Scientists have once again affirmed the 2000-2020 total greenhouse effect (longwave) forcing has been declining in recent decades just as absorbed solar radiation has been increasing due to cloud albedo modulation. The latter explains the net positive Earth Energy Imbalance (EEI) and consequent global warming during this period. Recently we detailed the satellite-observed decline in […]

Adding reflectors to roofs and pavements and similar strategies could globally reflect 87 W/m² more incoming solar radiation than is reflected on an annual basis currently, cooling the surface. In contrast, the sum of the accumulated annual anthropogenic radiative forcing from greenhouse gases (GHG) since 1750 is 2.72 W/m². A new study analyzes the effectiveness […]

From about 11,000 to 9,000 years ago the summer solar irradiance absorbed by the Earth’s surface has been estimated to be 40-60 W/m² greater than today from latitudes 40°N to 70°N (Ullman et al., 2015). These values seriously undermine the claim CO2 is the driver of climate change. Image Source: Ullman et al., 2015 Despite […]

There has been a “strong upward trend” in solar radiation over the European continent since the 1980s driven by natural ocean circulation factors responsible for “triggering and controlling the entire chain of events in climate processes.” A new study references Dr. Michael Mann’s claim that “changes in SST and heat resources in the waters of […]

“The IPCC concept that increasing carbon dioxide in the atmosphere causes global warming is three decades out-of-date.” − Lightfoot and Ratzer (2022), Journal of Basic & Applied Sciences In analyzing UAH global temperature and Mauna Loa CO2 records from 1979 to 2021, climate researchers Lightfoot and Ratzer (2022) report there has been “little, if any” […]

Scientists: Due to the decline in solar geomagnetic activity the Earth is poised to endure a cooling period over the coming decades, with the coldest temperatures arriving by 2038 or 2039 ±11 years. Human greenhouse gas emissions are not likely the cause of recent temperature changes; geomagnetic activity is. Nor will greenhouse gases reverse the effects […]

A remarkable publication on solar influence on climate goes unnoticed By Prof. Fritz Vahrenholt (Die kalte Sonne) (Text translated/edited by P. Gosselin) On November 3, 2021, the renowned scientific journal Climate published a paper on solar influence on climate. The paper by the renowned solar researcher Dr. Frank Stefani from the Helmholtz Zentrum Dresden-Rossendorf is […]

Scientists publishing in GRL once again affirm that in recent decades the dominant mechanism driving surface melt for the Greenland ice sheet has been downwelling shortwave radiation modulated by clearer skies (fewer clouds) and natural wind pattern changes. Greenland’s ice melt has not been driven by “longwave heating” from greenhouse gases in the last decades […]

Scientists continue to affirm the critical role of clouds in modulating the Earth’s energy budget, and, hence, the climate. The total net forcing of the entirety of the CO2 influence on climate has been less than 2 W/m² since 1750 (Feldman et al., 2015). Image Source: Feldman et al., 2015 On a per-decade basis, a 22 […]

Three new studies affirm the increase in absorbed solar radiation associated with decreased reflection by clouds (albedo) has been the “root cause” of the positive Earth Energy Imbalance and global warming since the early 2000s. Scientists (Loeb et al., 2021) have determined the rather uncertain positive trend in Earth’s Energy Imbalance (EEI) from 2005 to […]
