Extent of Antarctic sea ice reaches record levels, scientists say

Antarctic scientists have declared a new record has been set for the extent of Antarctic sea ice since records began. Satellite imagery reveals an area of about 20 million square kilometres covered by sea ice around the Antarctic continent. Jan Lieser from the Antarctic Climate and Ecosystems Cooperative Research Centre (CRC) said the discovery was made two days ago. "This is an area covered by sea ice which we've never seen from space before," he said.
