After reaching the minimum on September 18, Arctic sea ice extent has been steadily increasing. With the passage of the equinox, the sun has set at the North Pole.

Arctic

Summer in the Arctic is drawing to a close, and sea ice extent is likely to remain higher than in recent years. Several polynyas have formed poleward of 85 degrees North within the pack as well as areas near the thin ice edge.

Arctic

As the sun dips lower on the horizon, air temperatures over the central Arctic Ocean are dropping to near freezing conditions.

Arctic

The seasonal decline in Arctic sea ice extent from mid-July onward has proceeded at a near average pace. Extent is currently well below average, but above that observed for recent years.

Antarctica
Arctic

Arctic sea ice extent continued its summer decline. Extent is below average but not as low as in recent summers. In the Antarctic, sea ice extent is currently at record low levels for this time of year.

Arctic

Both of Earth’s polar regions had low sea ice extent for the month of June, with Antarctic sea ice setting a record low. Arctic sea ice extent stands at tenth lowest.

Antarctica
Arctic

Sea ice extent near both poles was again below average, but higher than in recent years for most of the month.

Arctic

Arctic spring melt has begun. Ice extent declined most substantially in the Bering Sea and the Sea of Okhotsk. Overall decline was slower than average through the month.

After reaching its seasonal maximum extent of 14.88 million square kilometers (5.75 million square miles) on February 25, the seasonal decline in Arctic sea ice extent through March proceeded in fits and starts.

While January began with sea ice extent below average, by the end of the month, extent increased. January 2022 finished as the sixteenth lowest extent in the satellite record above all years since 2009.

By early January 2022, Arctic sea ice extent, while well below average, was within the lowest decile of recorded extents of the 1981 to 2010 reference period.

Sea ice extent increased at a faster than average pace through November and by the end of the month, extent was just within the interdecile range.

The sea ice extent has been quickly growing, and by the end of October, ice covered most of the Arctic Ocean.

The summer melt season has come to a modest end. The summer of 2021 was relatively cool compared to the most recent years and September extent was the highest since 2014. It was nevertheless an eventful summer, with many twists and turns.

Arctic

On September 16, Arctic sea ice likely reached its annual minimum extent of 4.72 million square kilometers (1.82 million square miles). The 2021 minimum is the twelfth lowest in the nearly 43-year satellite record.

The Arctic sea ice minimum extent is imminent. After a cool and stormy summer, this year’s minimum extent will be one of the highest of the past decade, despite the amount of multiyear ice standing at a near-record low.
