Our friend “Snowfan” here reports the sun has now gone 30 days without sunspots as we progress into solar cycle 25. A number of scientists have been warning that the earth may be heading into a cooling phase due to lower sunspot activity over the past 15 years. Is cooling in the works? Solar activity […]

Echoing the determination of NASA scientists, a new study suggests the natural variability in cloud cover allowing more solar radiation to be absorbed by the Earth’s oceans drove the 2014-2020 global warming. NASA scientists (Loeb et al., 2018) used satellite data to assess the 2014-2017 warming was driven by a +0.83 W/m² shortwave forcing due to […]

The magnitude of claimed global warming since the mid-1800s has tripled from 0.56°C to 1.72°C in the last few years. As recently as 1994, the IPCC claimed global surface temperatures had risen “0.3 to 0.6°C” (0.45°C) since 1861. By 2001, it was changed to 0.61°C warming from 1861 to 2000 (IPCC TAR 2001).

In a new climate reconstruction for the Tibetan Plateau (Liang et al., 2020), scientists report a) the highest Holocene temperatures occurred about 8,500 to 6,000 years ago; b) “century-scale climate fluctuations” correlate “statistically and visually” with solar forcing estimates; and c) “we are in the middle of the 500-yr-long relatively warm period” and “this natural […]

An observational analysis of photometric evidence suggests solar forcing of Earth’s atmosphere could vary by as much as ±4.5 W/m² since 1750, which is “far larger than the IPCC estimate of −0.30 to +0.10 W/m²” (Judge et al., 2020). A 2017 study suggested the solar activity during the “modern maximum period from 1940 to 2015” […]

Image: NASA Earth Observatory. Public Domain Prof. Fritz Vahrenholt’s Monthly Solar Report The global mean temperature in April 2020 was again significantly lower than in February and March, at 0.38°C above the average from 1981 to 2010. The average temperature increase on the globe from 1981 to February 2020 was 0.14°C per decade. The further […]

Dr. Ludger Laurenz The sun has left its signature in data from numerous weather stations, thus challenging meteorologists and climate researchers who falsely claim the sun plays only a minor role. Image: NASA Earth Observatory (public domain). In the 11-year sunspot cycle (Schwabe cycle), the sun generates a start impulse in the sunspot maximum year. Triggered […]

Using NASA’s MERRA-2 radiation data, scientists find shortwave radiation (SW) has been rising since the 1980s. The SW increase has been larger and faster than longwave radiation (LW) changes during this same timespan. Cloud variability has been the “main driver” of these trends. Image Source: Delgado-Bonal et al, 2020 In a new Nature journal paper (Delgado-Bonal […]

In 2019, more than 440 scientific papers were published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…or that otherwise serve to question the efficacy of climate models or the related “consensus” positions commonly endorsed by policymakers and mainstream media sources. Image Source: Collins et al., 2019 […]

The Munich Climate Conference 2019 By Dr. Andreas Mueller (Summarized by P. Gosselin) Last weekend the climate conference by the Germany-based European Institute for Climate and Energy EIKE took place in Munich, despite threats by leftist radicals. More than a dozen leading international climate experts presented views that severely challenge mainstream alarmist climate science. 1. […]

International and NASA solar scientists find their Total Solar Irradiance reconstruction extending to 1700 can “correlate well” with Earth’s global temperature records, including a positive net TSI trend during 1986-2008. A new Grand Solar Minimum is expected to commence during the 2030s. Surface climate records that have been uncorrupted by coastal (ocean-air)/urbanization biases suggest there […]

The last 40 years of global temperature changes can be radiatively explained by a natural reduction in cloud cover. From 1979 to 2011, satellite data provide documentation of a reduction in cloud cover and aerosol depth that allowed an additional 2.3 W/m² of positive shortwave energy to be absorbed by the Earth’s surface rather than […]
