Within the past few years, more than 50 papers have been added to a compilation of scientific studies that refute the primary claim of climate-change activists that CO2 causes global warming.
The papers compiled by the NoTricksZone website, now numbering 106, find that CO2 has a minuscule effect on climate.
Words such as “negligible” are used to describe CO2’s effect on the climate.
A 2019 paper, for example, noted that the “enhancement of the atmospheric greenhouse effect due to the increase in the atmospheric greenhouse gases is often considered as responsible for global warming.”
But the analysis by Costas Varotsos and M.N. Efstathiou of the National and Kapodistrian University of Athens “did not show a consistent warming with gradual increase (in CO2) in low to high latitudes in both hemispheres, as it should be from the global warming theory.”
“Based on these results and bearing in mind that the climate system is complicated and complex with the existing uncertainties in the climate predictions, 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,” the researchers write.
