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 […]

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 […]

By Die kalte Sonne The Copernicus program offers very interesting data on Arctic ice. While sea ice has been declining off the Greenland Sea (east of the island), the Chucki Sea (eastern Siberia) shows a very different trend in sea ice extent over the past year. Such deviations have occurred repeatedly since the year 2000. […]

Of California’s 23 vulnerable bird species studied (barn owls, golden eagles, road runners, yellow-billed cuckoos…), scientists have found 11 are now experiencing at least a 20% decline in their population growth rates because wind turbines and solar panels are killing them and/or destroying their limited-range habitat. California’s mild-winter Mediterranean climate is home to some of […]

The net climate forcing from albedo changes can account for the increase in ocean heat content in recent decades. Scientists (Goode et al., 2021) have determined Earth’s albedo declined from 1998-2017, driving a +0.5 W/m² net increase in absorbed solar radiation, a positive energy imbalance. Image Source: Goode et al., 2021 The authors report it […]

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 […]

Scientific flaws in IPCC climate models and the IPCC AR6 problems cover-up…IPCC climate models ignore the strong increase in solar radiation since 2001 By Prof. Antero Ollila According to the latest IPCC Assessment Report 6 (AR6), the observed temperature increase and the calculated temperature increase according to climate models have been almost the same 1.3 […]

Here 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 this […]

China’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 Ice […]

Analyzing 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 parameters […]

Over 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 cover […]

Significant influence of solar activity on winter temperature in Scandinavian polar night So far, much of Europe has seen a cold and wet 2021. It may be related to solar cycles. An essay at Die kalte Sonne by Dr. Ludger Laurenz looks at the relationship between solar activity and weather trends, and believes this summer’s […]
