Antarctic glaciers in mass retreat

Almost all the glaciers that flow into the sea off the Antarctic Peninsula are retreating. The discovery comes from an analysis spanning more than half a century of aerial photographs and satellite images.
"Fifty years ago most glaciers were slowly growing in length, but the pattern is now reversed and they're shrinking," the British Antarctic Survey's Alison Cook told a press conference in London. Of 244 glaciers studied, 87% have shown a net retreat since photographic evidence was first collected in the 1940s, says Cook, who led the project.
The trend is probably linked to local climate changes on the peninsula, she explains, where temperatures have risen by around 2ºC over the past 50 years. This is much more than the average temperature increase seen in the rest of Antarctica.
