Atlantic weather pattern shaped southern Greenland's rain and snow for millennia, sediments reveal

AI Summary

Sediment evidence indicates that Atlantic weather patterns, including the North Atlantic Oscillation, shaped rain and snowfall in southern Greenland over thousands of years. The findings are relevant to understanding how rising Arctic temperatures and shifting precipitation may affect ice sheets and glaciers in the region.

In high-latitude coastal areas, Arctic amplification means that temperatures are rising faster than the global average. This combination of rising temperatures and changing precipitation patterns driven by the North Atlantic Oscillation has major impacts on regions with a "cryosphere"—areas that host ice sheets and glaciers, such as southern Greenland.
