The Western Antarctic Peninsula has one of the world's highest increase in temperatures.
May 2015 Science Dynamic thinning of glaciers on the Southern Antarctic Peninsula Satellites have recorded a sudden dramatic change in the behaviour of glaciers on the Antarctica Peninsula, according to a Bristol University-led study. The ice streams were broadly stable up until 2009, since when they have been losing on the order of 56 billion tonnes of ice a year to the ocean. A 21 May UK Mail article describes the dramtic finding.
Research in 2012 found the rate of West Antarctic warming is double the estimated rate which is 3X the global averager warming rate. Over winter time the warming is even faster at 10X the global average.

The findings of the 21-year study by Nasa and the University of California, Irvine claim to provide the most accurate estimates yet of just how fast glaciers are melting in the Amundsen Sea Embayment.
They lost an average 83 gigatons per year (91.5 billion US tons), or the equivalent of losing the water weight of Mount Everest every two years.
Global warming caused the melt rate of glaciers in west Antarctica to triple in the past 10 years.
That surge means the glaciers lost a Mount Everest-sized amount of water every two years over the past 21 years, at roughly a mass of 91.5 billion tons per year, according to scientists at NASA and the University of California-Irvine.
Oct 2014 in Nature the Southern Ocean has been warming faster that previously estimated, as more heat has been added to the climate system than had been thought.
Mar 2015 Volume loss from Antarctic ice shelves is accelerating. Overall, average ice-shelf volume change accelerated from negligible loss at 25 ± 64 km3 per year for 1994-2003 to rapid loss of 310 ± 74 km3 per year for 2003-2012. West Antarctic losses increased by 70% in the last decade, and earlier volume gain by East Antarctic ice shelves ceased. In the Amundsen and Bellingshausen regions, some ice shelves have lost up to 18% of their thickness in less than two decades.
In May 2014 research discovered that the Western Antarctic Peninsula is in a state of irreversible collapase. It should take a long time to go but after it does the rest of the Antarctic ice sheet is expected to go to. Interview at AGU here
The concern has been the Ice collapsing into the sea with warming, but Antarctica also has methane hydrate which should be a far greater and sooner concern.
Before the climate cooled 35 million years ago, large amounts of organic matter were produced by abundant Antarctic plant growth and accumulated in Antarctic basins now covered with ice. Low oxygen conditions under the ice have been favorable for biological processes to convert organic matter into methane and for the ice to trap it.
The melting peripheral ice is exposing methane emitting organic material
Antarctic atmospheric methane shows the post 2007 renewed increase in methane as other latitudes do.
