Ice shelf collapse was biggest for 10,000 years

Although the disintegration of ice shelves does not itself cause sea levels to rise (because they are already floating), their loss is thought to speed up the flow of ice from ice sheets on land, causing sea levels to rise. Larsen B's smaller neighbour, Larsen A, broke off in 1995 and other much bigger ice shelves nearby, such as the Ross and Ronne, are also considered to be at risk of disintegrating, according to studies by the British Antarctic Survey in Cambridge.

Researchers have measured a 2.5C increase in average temperatures in the Antarctic peninsula over the past 50 years and many scientists believe there is little doubt that this rise can be linked to global warming and climate change exacerbated by man-made pollution.
