New Study Finds Rising CO2 COOLS The Arctic
The CO2-induced “polar amplification” narrative peddled by climate alarmists has just taken another hit
It has been shown previously that increasing CO2 by more than 120 ppm (from 278 to 400 ppm) cools the Antarctic climate (Notholt et al., 2024).
Researchers report that increased carbon dioxide induces cooling in the Arctic’s lower atmosphere.
These scientists found that there has been a slight (-0.01°C) net cooling effect of CO2 in Antarctica since 1750.
Now, a new study suggests Arctic CO2 cooling may occur as increasing concentrations of CO2 and CH4 radiatively cool the Arctic, too.
Rising concentrations of ‘greenhouse gases’ – presumed to be derived from anthropogenic emissions – induce Arctic cooling “primarily due to the near-saturation of infrared absorption [CO2 and CH4] in the lower atmosphere”.
“In the lower atmosphere (>700 hPa), the magnitude of the CO2 kernel decreases significantly, indicating a weaker suppression of outgoing longwave radiation by increased CO2 concentrations. …
“In the lower atmosphere, from the surface to approximately 400 hPa, the heating rate [derived from increasing CO2] exhibits relatively large negative values, indicating strong radiative cooling. …
“…the heating rate remains negative at all levels, indicating the longwave radiation leads to net atmospheric radiative cooling. …
“…the observed vertical structure enhances outgoing longwave radiation compared with the uniform distribution, thereby strengthening radiative cooling in the Arctic atmosphere.”
If increasing CO2 leads to radiative cooling in the Antarctic and Arctic, then CO2 cannot be a driver of polar ice sheet, glacier, or sea ice melt.

As CO2 has only three narrow IR absorption/emission bands, equivalent to blackbody radiation of objects at 800, 400, and -80 deg C, only the last is ever used in the atmosphere such that CO2 is constantly, 24/7 emitting -80 deg C IR that is lost to space as everything in the atmosphere and the planet is hotter than this and thus these energy levels are already full. In fact, CO2 has not been shown to warm anything despite physicists’ attempts. It is the world’s best refrigerant, being abundant, stable, nontoxic, nonflammable, and cheap. It is being used now as the primary refrigerant in new ice rinks and Mercedes car A/C units.
This is on top of the fact that there is no such thing as a greenhouse gas or effect.
