Three to five million years ago, when carbon dioxide concentrations in the atmosphere were similar to those predicted for the end of this century, the enormous ice shelf buckled several times, triggering the collapse of West Antarctica.

Ice cores collected from the island reveal what ocean conditions were like over the tens of thousands of years, giving an indication of how sensitive the ice is, and what might happen if history is repeated.
