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