An important ice shelf responsible for pinning back much of the West Antarctic Ice Sheet is in danger of collapse, according to new studies out today. Ice-penetrating radar has discovered giant pools of sea-water underneath much of the ice shelf; models suggest that warm waters melting it from beneath may cause the shelf to give way. That could potentially open the gates to the great mass of ice stacked up behind it - and more significant sea level rises. West Antarctic ice shelf - a nudge and a push from collapse?
