The sea ice in the polar regions is an important indicator for global climate change, as the two regions are essentially our planet’s early warning system. The loss of sea ice is a direct effect of gl
After the summer minimum in the Antarctic, sea-ice growth rebounding sluggishly On 31 March 2024, the Antarctic sea-ice extent, at 4.52 million square kilometres, reached its maximum for the month of
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
The annual development of the sea-ice extent is one of the most important parameters for describing the seasonal progression of sea-ice development. It is particularly relevant when combined and compa
Visualising scientific data is no mean feat and certain technical requirements must be met. At the same time, when the goal is to convey information to a given target group in a clear and appealing wa
This year, sea-ice development in the Antarctic is progressing extremely slowly and, after May, once again reached a record-low monthly sea-ice extent in June. At 11.23 million km², the monthly mean s
Not until the end of the month did the sea-ice extent substantially decline, dropping below two standard deviations from the average for the period 1981 – 2010. At the same time, the summer solstice w
While the summer minimum was reached in the Antarctic on 19 February 2020 (at 2.68 million km²), in the Arctic the extent has been growing steadily since the end of February, and hasn’t yet reached it
On 4 March 2020, the Arctic sea-ice extent reached its winter maximum at 14.98 million km² and has been steadily declining ever since. The value is now hovering near the bot-tom limit of two standard
Particularly in the Bering Sea, but also in the Sea of Okhotsk and eastern Barents Sea, the amount of sea ice was below the long-term average for 2003 – 2014. In contrast, the ice margin was above the
