The collapse of Larsen B, showing the diminishing extent of the shelf from 1998 to 2002. From 31 January 2002 to March 2002 the Larsen B sector partially collapsed and parts broke up, 3,250 km 2 (1,250 sq mi) of ice 220 m (720 ft) thick, an area comparable to the US state of Rhode Island . [ 13 ]

Retreat and collapse of the Larsen Ice Shelf is constantly monitored by analyzing satellite imagery, GPS positioning and terrain data to investigate the ice-climate interactions in critical areas under climate change conditions. [3]
When the A-68 iceberg calved from the Larsen C ice shelf it weighed up to a trillion tonnes, and measured 2,300 square miles, a quarter of the size of Wales.
The collapse of the Larsen B shelf was preceded by thinning of just 1 metre per year, while some other Antarctic ice shelves have displayed thinning of tens of metres per year. [5] Further, increased ocean temperatures of 1 °C may lead to up to 10 metres per year of basal melting. [ 5 ]
