Share this…FacebookTwitter“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IPCC concept that increasing carbon dioxide in the atmosphere causes global warming is three decades out-of-date.”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 […]

Share this…FacebookTwitterScientists: 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 […]

Share this…FacebookTwitterA 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 […]

Share this…FacebookTwitterScientists 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 […]

Share this…FacebookTwitterScientists 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 […]

Share this…FacebookTwitterThree 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 […]

Share this…FacebookTwitterThe One Oscillation That Rules Them All By David Archibald Cumulative graphs, in which changes in the individual values from time period to time period are added, are powerful for showing changes of trend in a series. Thus the cumulative graph of the annual average solar aa Index (a geomagnetic index) nails the beginning […]

Share this…FacebookTwitterHere are 3 reasons why global surface temperatures will probably see continued cooling over the coming year. 1. La Nina back in the forecast NASA continues to project La Niña conditions into 2022 thus suggesting vigorous globally time-shifted cooling conditions: Source. NASA The NOAA-ENSO forecast also shows La Niña conditions taking hold again later […]

Share this…FacebookTwitterNot long ago Dr. Roy Spencer published Version 6 University of Alabama-Huntsville satellite-based global average lower tropospheric temperature (LT) anomaly for June, 2021. It was -0.01 deg. C, down an impressive 0.7°C since the peak in early 2016. As Dr. Spencer’s chart above shows, temperatures are back within the range seen 20 years ago. […]

Share this…FacebookTwitterChina’s climate history includes multiple climate warming and cooling fluctuations of 4°C within centuries, with cold periods aligning with declines in solar irradiance. According to a new study (Zhang et al., 2021), northern China’s coldest temperatures of the last 5000 years occurred 300 calibrated years before present (cal yr BP), coinciding with the Little […]

Share this…FacebookTwitterAnalyzing the cyclic nature of solar activity, leading scientists suggest a solar minimum is set to persist until 2050. It’s important to estimate the features of the next solar cycle because they serve to improve preparedness in space exploration and minimizing risks in technological and sociological activities. The ability to understand historical solar magnetic […]

Share this…FacebookTwitterOver the US, the modest change in cloud cover from 1996-2019 predominantly drove the +11.77 W/m² surface solar radiation forcing during 1996-2012 (then -2.35 W/m² from 2013-2019). These “brightening” and “dimming” magnitudes easily overwhelm the values associated with an annual 2 to 2.5 ppm rise in CO2 forcing (0.2 W/m² per decade). When cloud […]
