Compared to an average winter over the last several decades, the maximum extent of Antarctic sea covered by ice shrank by two million square kilometres — an area four times the size of France, the BAS said.“This is why we were so interested in studying what climate models can tell us about how often large, rapid losses like this are likely to happen,” the study’s lead author Rachel Diamond told AFP.

Sea ice, which forms from freezing salt water already in the ocean, has no discernible impact on sea levels. “It doesn’t completely recover to original levels even after 20 years,” Diamond told AFP. That means “the average Antarctic sea ice may still stay relatively low for decades to come”, he added.
