Scientists finally figure out why the Antarctic Peninsula is melting
Scientists have been watching the Antarctic Peninsula melt for decades, but
are still just figuring out why.
The prevailing conclusion until recently had been that rising air
temperatures were causing the melt.
But it may be the water — warm water, according to research published in
this week's journal Science.
The study by researchers at Swansea University, Durham University and the
British Antarctic Survey says that warming in the waters around Antarctica
has corresponded with the "widespread acceleration of glacier retreat." In
addition, the melt is worse in the southern region, where some of the waters
are relatively warmer, than it is in the cooler water of the northwest
region.
Lead author Alison Cook found in a previous study that rising air
temperatures alone could not account for the degree of glacier retreat that
has been occurring, according to The Washington Post.
A patch of water known as the Circumpolar Deep Water, seems to be the force
driving the more rapid glacial melting in the southwestern Antarctic
Peninsula, the study concluded. In some areas, portions of the glaciers
extend outward into the ocean like shelves or wings. The warmer water could
be weakening these ice shelves from below, causing them to break off, and
dramatically increase the rate at which the glacier
retreats.
