Sea ice cover in Antarctica has dropped to its second-lowest on record, Australian authorities said Friday (Mar 2), adding that it was not yet clear what was driving the reduction after several years of record-highs. The report came as scientists said earlier this week that the Arctic region was seeing record high temperatures, with sea ice covering the smallest area in winter since records began more than half-a-century ago.
