The climate change dogma is roughly this:

• The concentration of carbon dioxide in Earth’s atmosphere has increased markedly over the past century (true);
• human activities have contributed to that increase (true);
• Earth has warmed by more than a degree since escaping the harsh Little Ice Age in the 19th century (also true, thank goodness!);
• temperatures will continue to rise to dangerous, catastrophe-inducing levels (unproven, unknowable, and unlikely) unless human society is radically transformed by drastically curbing the human use of fossil fuels (a power-seeking agenda that would inflict widespread impoverishment and suffering on billions of human beings).

Here are several recent examples of scientific dissent from the alarmist projections of the climate change cult:

• In Hydrological Sciences Journal, Demetris Koutsoyiannis and Christos Vournas found that the post-1900 increase in the CO2 concentration (from 300 parts per million to 420 parts per million) “has not altered, in a discernible manner, the greenhouse effect, which remains dominated by the quantity of water vapour in the atmosphere.”
• Writing in the journal Earth’s Future, W. Jackson Davis “documents an overall negative correlation between global temperatures and atmospheric CO2 concentrations over the last 210 million years,” according to NoTricksZone.com. A “negative correlation” —i.e., when the atmospheric concentration of CO2 rises, more often than not temperatures fall.
• Like other scientists in earlier years, Allan T. Emrén, writing in the International Journal of Global Warming, “found that the rate of change in CO2 concentration is controlled by global temperature rather than vice versa.”
• Norwegians John K. Dagsvik and Sigmund H. Moen (a statistician and civil engineer, respectively), writing in a Statistics Norway discussion paper, concluded that “the effect of man-made CO2 emissions does not appear strong enough to cause systematic changes in the temperature fluctuations during the last 200 years.”
• Other scientists believe that the “hottest ever” summer that the climate change cult has hyped in 2023 (which actually, according to National Oceanic and Atmospheric Administration data, was the 15th hottest since 1910 on mean temperatures and 22nd hottest for maximum temperatures) wasn’t triggered by CO2, but by a significant increase in solar radiation and/or by the 2022 eruption of the Tonga-Hunga volcano having caused a 10 percent increase in water vapor in the atmosphere.
• Perhaps the greatest challenge to the climate change cultists’ belief that CO2 will cause catastrophic global warming is a study published in Nature partner journal Climate and Atmospheric Science by H. Nair and colleagues. Those scientists came to the arresting conclusion that “we would expect from a 100% switchover from fossil fuels to zero-emission renewables, the net radiative heating would increase drastically.”
• This, according to NoTricksZone.com, is due to “a dramatic reduction in climate-cooling aerosol (pollution) emissions,“ and, ”because aerosol emissions have a relatively greater climate impact by reflecting shortwave radiation, the net effect of transitioning to renewables will be to ‘drastically’ increase Earth’s temperatures over the coming decades.”

The above examples of scientific studies running counter to climate-change-cult orthodoxy indicate that the science surrounding the issue is anything but settled in the alarmists’ favor.
