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 […]

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” […]

Global Cooling On The Horizon? Image Source: Abdussamatov, 2012 When it comes to the Sun’s influence on climate, one conclusion is certain: there is no widespread scientific agreement as to how and to what extent solar activity and its related parameters (i.e., galactic cosmic rays, geomagnetic activity, solar wind flux) impact changes in the Earth’s temperature and […]

In two new papers, scientists affirm a strong connection between solar activity and the Earth’s climate, as temperatures are said to be 3 times more sensitive to solar forcing than CO2 forcing. With the advent of a grand minimum in the coming decades, a consequent “dampening” of temperatures (and slowing of sea level rise) is […]

‘Two-Thirds Of Climate Warming’ Since 1750 Due To ‘Solar Causes’ – Dr. Alan D. Smith, Geoscientist Though advocates of the dangerous anthropogenic global warming (AGW) narrative may not welcome the news, evidence that modern day global warming has largely been driven by natural factors – especially solar activity – continues to pile up. Much of […]

Scientists: It’s The Sun “The emerging causal effects from SS [solar activity] to GT [global temperatures], especially for recent decades, are overwhelmingly proved” – Huang et al., 2017 “Climate … follows SA [solar activity] fluctuations on multidecadal to centennial time scales” – Moreno et al., 2017 “The solar ‘activity’ increase is the chief driver of […]

Most Of Warming Trend Since 1980s Is Naturally Driven, Not CO2-Driven According to a new statistical analysis of centennial-scale surface temperature changes, half (0.5 °C) of the warming trend over the last 135 years (0.95 °C) can be explained by both (a) the existence of commonly-occurring natural (non-anthropogenic) variations of temperature that can reach the […]

One of the oft-stated “truths” for advocates of the position that humans are predominantly responsible for climate changes is that the Sun could not have played more than a negligible role in the global warming of the last few centuries. Indeed, the latest Intergovernmental Panel on Climate Change (IPPC) report theorizes that the long-term solar […]

28 January, 2017 – Now updated to 133 papers In 2014, there were at least 93 peer-reviewed scientific papers published in scientific journals affirming the Sun’s influential role in climate change. In 2015, there were at least 95 scientific papers affirming the Sun-Climate link. Already in 2016, there have been over 100 papers (107 to […]
