Antarctica's Sea Ice concentration. The point is, the ice on the continent is melting. And huge glaciers make their way towards the Antarctic coast right into the sea extending the ice border. Just a thought.

West Antarctica is currently experiencing a net outflow of glacial ice, which will increase global sea level over time. A review of the scientific studies looking at data from 1992 to 2006 suggested a net loss of around 50 Gigatonnes of ice per year was a reasonable estimate (around 0.14 mm of sea level rise). Significant acceleration of outflow glaciers in the Amundsen Sea Embayment may have more than doubled this figure for the year 2006.

In 2003 the Antarctic Peninsula's Larsen-B ice shelf collapsed. Between 28 February and 8 March 2008, about 570 square kilometers of ice from the Wilkins Ice Shelf on the southwest part of the peninsula collapsed, putting the remaining 15,000 square kilometers of the ice shelf at risk. The ice was being held back by a "thread" of ice about 6 km wide, prior to its collapse on April 5, 2009. According to NASA, the most widespread Antarctic surface melting of the past 30 years occurred in 2005, when an area of ice comparable in size to California briefly melted and refroze; this may have resulted from temperatures rising to as high as 5 C (41 F).
