Researchers confirm dramatic meltdown
Dawn in the Antarctic Sound.
FRISCO — A new study once again confirms the rapid warmup of the Antarctic Peninsula, due to shifting wind patterns. The increased temperatures are manifesting in a longer melt season, with potentially huge consequences for ecoystems and physical features, including coastal ice shelves, which are already cracking and crumbling. There have already been big shifts in penguin populations, and krill, at the base of the Southern Ocean food web, is also at risk.

Longer melt seasons on the Antarctic Peninsula have been linked with disintegration of ice shelves, possibly due to surface melt water eating away at the ice.
