An animation of the annual Arctic sea ice minimum with a graph overlay showing the area of the minimum sea ice in millions of square kilometres 2018 sea ice extent visualization Observation with satellites shows that Arctic sea ice area, extent, and volume have been in decline for a few decades.

This visual shows the Arctic sea ice change and the corresponding absorbed solar radiation change during June, July, and August from 2000 through 2014. The Arctic ice pack is the sea ice cover of the Arctic Ocean and its vicinity. The Arctic ice pack undergoes a regular seasonal cycle in which ice melts in spring and summer, reaches a minimum ...
English: Plot of estimated development of arctic sea ice volume between 1979 and now. Blue curve are data as determined by the numerical model PIOMAS. Blue curve are data as determined by the numerical model PIOMAS.
The post is wrong about Arctic sea ice and climate change. On Dec. 21, 2024, the Antarctic sea ice extent was higher than on Dec. 21, 2016, but the Arctic sea ice extent was lower on that date in ...
There are no Arctic-wide or Antarctic-wide measurements of the volume of sea ice, but the volume of the Arctic sea ice is calculated using the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) developed at the University of Washington Applied Physics Laboratory/Polar Science Center. PIOMAS blends satellite-observed sea ice ...
The Arctic has already lost about half of its sea ice, compared to the 1980s at the end of the summer. It is known that more warming has delayed ice formation, and resulted in thinner sea ice growth.
English: Plot of arctic sea ice extent development between 1979 and 2023 in monthly mean values. For the determination of the "area" value, every pixel with a sea ice concentration > .15 is taken. The pixel area is multiplied with the concentration value derived from the passive infrared signal.
The first ice-free days of the Arctic Ocean could occur as soon as the 2020s or 2030s — as many as 10 years earlier than previous projections.
