Thousands of emperor penguin chicks drowned when the sea-ice on which they were being raised was destroyed in severe weather. The catastrophe occurred in 2016 in Antarctica's Weddell Sea. Scientists say the colony at the edge of the Brunt Ice Shelf has collapsed with adult birds showing no sign of trying to re-establish the population.
A large iceberg in Antarctica has calved off the Larsen C ice shelf as of July last year and budged only a little from the coast until recently. In the past two months, the iceberg, known as 'A68', has taken a drastic 90 degree swing away from the Antarctic mainland and into the Southern Ocean.
