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).


Past interglacial CO2 levels of only 280 ppm were associated with a “nearly ice free” Greenland and the presence of flora and fauna in subarctic terrestrial environments 1000 km northwards of where they can survive today, implying “at least 5°C higher temperatures” (Bennike and Böcher, 2021). Summer sea water temperatures were as much as “7-8°C higher than at present”.
