Polar bears are not the only ones facing big changes. The decrease of sea ice in summer and the time of formation of new sea ice significantly determine air temperatures above the Arctic Ocean in autumn and winter. The higher the air temperatures, the more...
Sea ice, here with fragments from icebergs, has declined by one third in the Weddell Sea over the past five years. Photo: Julia Hager Scientists have found that summer sea ice in the Weddell Sea area of Antarctica has decreased by one million square kilometers –...
The behaviour of sea ice around the Antarctic continent has often puzzled climate scientists in recent decades, as it has not always kept to predictions. But now the mechanisms are a little clearer and the models more accurate. Photo: Michael Wenger The climatic...
