WASHINGTON
The ice pack typically reaches its largest size during the colder winter months, so the September 10 reading will likely remain this year's maximum. In February, at the height of the austral summer, the Antarctic sea ice pack had reached a minimum extent of 1.79 million square kilometers, also a record, according to the NSIDC.Meanwhile at the other end of the globe, where summer is drawing to a close, Arctic sea ice reached a low of 4.23 million square kilometers, the NSIDC said. It represents the sixth lowest minimum in 45 years of recordkeeping.For several decades, the Antarctic sea ice pack had remained stable, even expanding slightly.
The downward trend is “now thought to be linked to warming in the uppermost ocean layer,“ the NSIDC said.
