Huge ice core shows frightening change in Antarctica – “An uncontrollable process’. The West Antarctic ice sheet suddenly shrank dramatically at the end of the last ice age.

This is suggested by ice drillings that researchers from the University of Cambridge and the British Antarctic Survey examined. In one place, around 8,000 years ago, the ice sheet lost 450 meters of thickness in less than 200 years. The research team believes that the thinning of the ice may have been triggered by warm water getting under the ice.
