similarly frigid and storm-tossed Southern Ocean. In winter, sea ice up to 1.5 metres thick forms atop the water. Air temperatures over the sea ice can easily reach minus 30 degrees Celsius. Given its high [...] How much is the climate in Antarctic habitats changing? Which animals depend on the sea ice? What will the retreating sea ice mean for the Antarctic krill? Can the krill adapt to the new circumstances? Which [...] to the Antarctic Peninsula than in the past. As a result, the sea ice is dwindling, the ice shelves extending from the land into the sea are crumbling, and the glaciers are retreating. Conversely, in
