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 2024 compared to 2016, according to government data.
The ice extent trends from 1979 to 2002 have been a statistically significant Arctic sea ice decrease of −2.5% ± 0.9% per decade during those 23 years. [7] Climate models simulated this trend in 2002. [8] The September minimum ice extent trend for 1979–2011 declined by 12.0% per decade during 32 years. [9]
This image, taken from a data visualization, shows the Arctic’s sea ice minimum extent on September 11, 2024. The Arctic will be ‘ice-free’ when it has less than 1 million square kilometers ...
The Arctic Ocean is the mass of water positioned approximately above latitude 65° N. Arctic Sea Ice refers to the area of the Arctic Ocean covered by ice. The Arctic sea ice minimum is the day in a given year when Arctic sea ice reaches its smallest extent, occurring at the end of the summer melting season, normally during September.
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 sea ice-free September could occur as early as the 2030s, the study found. Arctic sea ice has been declining for decades but has shrunk at an even faster rate in the past 20 years.
Animation of Minimum Annual Sea Ice Extent over the Arctic from 1979 to 2012. In this animation, the daily Arctic sea ice and seasonal land cover change progress through time, from May 16, 2013, through September 12, 2013, when the sea ice reached its minimum area of coverage for 2013.
A result of these observations is a thorough record of sea-ice extent in the Arctic since 1979; the decreasing extent seen in this record (NASA Archived February 21, 2011, at the Wayback Machine, NSIDC), and its possible link to anthropogenic global warming, has helped increase interest in the Arctic in recent years. Today's satellite ...
