Equilibrium states of the volume of the Greenland Ice Sheet (GIS) (black dots) with respect to pre-industrial as a function of atmospheric CO2concentration (top left) and corresponding temperature anomaly (top right). The blue curve refers to increasing CO2concentration starting from the pre-industrial GIS, the other curves to decreasing CO2starting from a completely ice free GIS (red curve) and from intermediate states (yellow and purple curves), respectively. The bottom panel illustrates the GIS thickness at the points A–D. Credit:Geophysical Research Letters(2023). DOI: 10.1029/2022GL101827
The Greenland Ice Sheet covers 1.7 million square kilometers (660,200 square miles) in the Arctic. If it melts entirely, global sea level would rise about 7 meters (23 feet), but scientists aren’t sure how quickly the ice sheet could melt. Modeling tipping points, which are critical thresholds where a system behavior irreversibly changes, helps researchers…
