New Study Finds Rising CO2 Cools The Arctic
Researchers report that increased carbon dioxide induces cooling in the Arctic's lower atmosphere.

The CO2-induced “polar amplification” narrative peddled by climate alarmists has just taken another hit. [some emphasis, links added]
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).
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 greenhouse gases CO2 and CH4 radiatively cool the Arctic, too.
