There Is No Detectable Link Between Greenland’s Climate And Atmospheric CO2 Changes

Greenland’s climate changes are remarkably uncorrelated with climate model expectations and changes in atmospheric CO2.
When CO2 levels were in the mid-200s parts per million (11.7 to 4.5 thousand years ago) the Arctic and northern Greenland were 2-4°C warmer than now, ice margins were 80 km behind today’s, ice-free open water conditions prevailed, and Greenland warmed 10°C in just 60 years (Elnegaard Hansen et al., 2022)
In the last two decades, as atmospheric CO2 has increased by 25 ppm, Greenland warming “is not evident” (Matsumura et al., 2022). Instead, temperature stations document cooling trends
