“It is not possible to reliably support the view of the presence of global warming in the sense of an enhanced greenhouse effect due to human activities.” — Drs. Varotsos and Efstathiou, 2019 Image Source: Varotsos and Efstathiou, 2019 In a step-by-step dissection of the anthropogenic global warming (AGW) hypothesis, or “greenhouse hypothesis of global warming”, […]

There are large regions of the globe where observations indicate there has been no warming (even cooling) during the last decades to century. Climate models rooted in the assumption that fossil fuel emissions drive dangerous warming dismiss these modeling failures and project temperature increases of 3° – 10°C by 2100 for these same regions anyway. […]

Unmasking Marcott’s “Uptick” 20th century “uptick” from Marcott et al., 2013, RealClimate.org Almost immediately after it was introduced to the public, the lead author of Marcott et al. (2013) squelched the narrative that said the hockey-stick-shaped reconstruction he and his colleagues produced is a robust representation of modern global-scale temperature changes. In an interview with Marcott published […]

The strong correlation between Galactic Cosmic Rays (GCRs) and cloud formation has for decades been postulated as a primary mechanism for solar-driven natural climate change. Concisely, “When the Sun is active fewer cosmic rays reach the Earth and, with fewer low clouds, the world warms up” (Svensmark et al., 2017). Since about 2000, however, this […]

Hailed as ‘the last piece of the puzzle’ in codifying our understanding of the mechanism(s) that cause climate changes, scientists are increasingly turning to Sun-modulated cosmic ray flux and cloud cover variations as the explanation for decadal- and centennial-scale global warming and cooling. In other words, climate changes are increasingly being attributed to natural variability, […]

The Science Unsettles Image Source: Robertson and Chilingar, 2017 In just the first 8 weeks of 2018, 97 scientific papers have been 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 […]

‘Strong Influence Of Solar Activity’ On 1850s-2014 Ocean Temperatures, ‘Small Contribution From CO2’ According to the United Nations Intergovernmental Panel on Climate Change (UN-IPCC) and computer modeling, the Sun’s role in modern-era climate change checks in at somewhere slightly above nothing. Image Source: IPCC AR5 (2013) And yet it is increasingly evident that more and more scientists across the […]
