Discussed (preprint)

Latest update: 26 Mar 2023
This paper shows that the changes observed in the North of the Greenland ice sheet mainly result from Arctic sea ice decline and are less dependent on the atmospheric circulation variability in North-Atlantic sector. The sea ice decline, therefore, exerts another (indirect) anthropogenic-driven influence on mass loss in Greenland.
Short summary
To overcome internal climate variability, this study uses k-means clustering to combine NAO, GBI and IWV over the Greenland Ice Sheet (GrIS) and names the approach as the North Atlantic influence on Greenland (NAG). With the support of a polar-adapted RCM, spatio-temporal changes on SEB components within NAG phases are investigated. We report atmospheric warming and moistening across all NAG phases as well as large-scale and regional-scale contributions to GrIS mass loss and their interactions.
