The Greenland Ice Sheet is three kilometers thick and has the potential to raise global sea levels by seven meters if completely melted. Cryosphere regions such as these directly respond to peak global temperatures, even if temperatures are lowered again. This presentation from COP27 provided an overview of Greenland’s temperature threshold (the point at which near-complete loss is unavoidable) and underscored the importance of remaining within the 1.5°C limit of the Paris Agreement. Dr. Jason Box is a professor in glaciology at the Geological Survey of Denmark and served as a contributing author to the IPCC AR4, AR5, and AR6.
