Share this…FacebookTwitterIn 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 […]

Share this…FacebookTwitterAn 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 […]

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. […]

Share this…FacebookTwitterUsing 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.

Share this…FacebookTwitterIn 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.

Share this…FacebookTwitterThe 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. […]

Share this…FacebookTwitterInternational 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 […]

Share this…FacebookTwitterThe 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 […]

Share this…FacebookTwitterIn the last few years, hundreds of peer-reviewed scientific papers have been published linking changes in solar activity to Earth’s climate (2016, 2017, 2018). The evidence for a robust Sun-Climate connection continues to accumulate in 2019. When it comes to the Sun’s influence on climate, one conclusion is certain: there is no widespread scientific […]

The authors of a new study (Jiao et al., 2019) point out that temperature changes in the Tianshan mountains are “mainly influenced by the solar activity via the mean minimum temperature within approximately 11-year periods.” Despite some warming since […]
