The CO2-induced \u201cpolar amplification\u201d narrative peddled by climate alarmists has just taken another hit.<\/strong><\/h4>\n\n\n\n

It has previously been shown increasing CO2 by over 120 ppm (278 ppm to 400 ppm) cools the Antarctic climate (Notholt et al., 2024<\/a><\/strong>).<\/p>\n\n\n\n

These scientists found there has been a slight (-0.01\u00b0C) overall net cooling CO2 influence since 1750.<\/p>\n\n\n\n

Now a new study<\/a><\/strong> shows increasing the greenhouse gases CO2 and CH4 radiatively cools the Arctic too.<\/p>\n\n\n\n

Rising concentrations of greenhouse gases \u2013 presumed to be derived from anthropogenic emissions \u2013 induce Arctic cooling \u201cprimarily due to the near-saturation of infrared absorption [CO2 and CH4] in the lower atmosphere\u201d.<\/p>\n\n\n\n

\u201cIn 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.\u201d<\/em><\/p>\n\n\n\n

\u201cIn 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.\u201d<\/em><\/p>\n\n\n\n

\u201c\u2026the heating rate remains negative at all levels, indicating the longwave radiation leads to net atmospheric radiative cooling.\u201d<\/em><\/p>\n\n\n\n

\u201c\u2026the observed vertical structure enhances outgoing longwave radiation compared with the uniform distribution, thereby strengthening radiative cooling in the Arctic atmosphere.\u201d<\/em><\/p>\n\n\n\n
