The immense effort of the past 52 expeditions has paid off: 40,000 km of measurement data document the significant decrease in pack-ice thickness as a result of climate change. In some regions, the re

The rapid decrease in sea-ice over the last six years is very surprising because the ice cover had hardly changed in the previous thirty-five years. This year the Antarctic sea ice was already at its

Large patches of ice-free water could especially be found in Canada’s Arctic coastal waters, and in the Barents and Kara Seas. In the Antarctic, the amount of pack ice was chiefly far below the long-t

Markedly low levels of winter sea ice in the Barents Sea and Bering Sea; Arctic is losing substantial amounts of older sea ice through Fram Strait In Svalbard, meteorologists observe rapid temperature

The sea-ice extent in the polar regions are indicators for the general state of ice development and the effects of climate warming in the high latitudes. For roughly eight years now, we have seen a si

The sea-ice cover in the Antarctic is below the long-term mean for the years 1981 – 2010 for a third consecutive year. To date, research has not yielded a conclusive answer to the question of how the

Development in the Arctic The slight upward trend following the Arctic minimum continued in early 2024; although the sea-ice extent was below the mean value for the years 1981 – 2010 at the beginning
