Collapse of Antarctic ice shelf could have global effects
The unprecedented collapse of an ice-shelf in Antarctica could indirectly lead to a significant rise in global sea levels, researchers say.
The Larsen B ice shelf covered more than 3,000 square kilometres and was 200 metres thick until its northern part disintegrated in the 1990s. Three years ago, the central part also broke up.
An international team of researchers used data collected from six sediment cores near the former ice shelf to show the shelf had been relatively intact for at least 10,000 years or since the last ice age.
