Ice of the arctic sea is vanishing, the weather systems over Greenland is dogged and the far-flung surface ice melting on the massive island.These dramatic trends and global sea-level rise are linked according to the study.
During Greenland summers, melting Arctic sea ice favors stronger and more frequent blocking-high pressure systems, which spin clockwise, stay largely in place and can block cold, dry Canadian air from reaching the island. The highs tend to enhance the flow of warm, moist air over Greenland, contributing to incresed extreme heat events and surface ice melting, according to the study.
