The rapid collapses of two ice shelves on the Antarctic Peninsula over the past quarter-century were most likely triggered by the arrival of huge plumes of warm, moisture-laden air that created extreme conditions and destabilized the ice, researchers said Thursday.
A chunk of Antarctic ice that was one of the biggest icebergs ever seen has met its end near South Georgia. Scientists will be studying its effects on the ecosystem around the island for some time.
