This year, Antarctic sea ice extent reached its annual maximum extent of 17.2m square kilometres (km2) on 19 September, according to the NSIDC. This is the second lowest in a satellite record stretching back 46 years, and 1.6m km2 smaller than the 1981-2010 average maximum, the NSIDC notes.
Antarctic sea ice maximum in 2024 is ‘second lowest’ on record
Antarctic sea ice has reached its maximum extent for the year, clocking in at the second lowest in a record stretching back to 1979, according to provisional data from the US National Snow and Ice Data Centre (NSIDC).
Over the past two years, Antarctic sea ice has been “way outside anything we have witnessed in our satellite record for their winter months”, an expert tells Carbon Brief.
Meanwhile, at the Earth’s other pole, the Arctic reached its summer minimum extent on 11 September, ranking as the seventh lowest on record, according to the NSIDC.
The organisation notes that “the last 18 years are the lowest 18 Arctic sea ice extents in the satellite record”.
The combination of below-average Arctic and Antarctic sea ice extents means that global sea ice extent has been at near-record lows over the past six months.
Antarctic maximum
For decades, scientists have been using satellite data to track the annual cycle of sea ice growth and melt at the world’s poles. This is a key way to monitor the “health” of sea ice in both the Arctic and Antarctic.

However, the NSIDC cautions that there is “some uncertainty in the estimate and date of the maximum because of an outage in the input source data” over 12-18 September.
Dr Zack Labe is a research physical scientist at NOAA’s Geophysical Fluid Dynamics Laboratory. He tells Carbon Brief that there is ongoing research in the polar community to understand whether Antarctic sea ice is undergoing a “regime shift”.
He adds that the past two years have been “way outside anything we have witnessed in our satellite record for their winter months” for Antarctic sea ice.
For example, Dr Ariaan Purich – from the school of Earth, atmosphere and environment at Monash University – explains to Carbon Brief:
“Our research suggests ocean warming has been important in pushing sea ice into this low-coverage state, and we also see preliminary indications of changed sea ice behaviour, suggesting that the underlying processes controlling Antarctic sea ice coverage may have altered.”
Global sea ice extent – a metric that combines Arctic and Antarctic sea ice extent – is currently tracking near the record low extent set last year.

You mean there was a time when there was no suffering or death on planet Earth?
I don’t believe it.
