What's happening instead is when summer sea ice is very low, as in 2016, it triggers ocean warming that persists. It takes about three years for the system to fully recover.

The team found that in summers with low sea ice since 2016, the loss of sea ice led to a 0.3°C rise in the average temperature in the Southern Ocean between the latitudes of 65° and 80° south.

Antarctic sea ice is more than just a platform for penguins. The sea ice's high reflectivity influences the whole Earth's climate, and the ice is a key habitat for underwater as well as above ...

Record low sea ice Since 2015, Antarctica has displayed record-low sea ice extent, according to the study, which appeared in the peer-reviewed journal Proceedings of the National Academy of Sciences.

Low sea-ice area negatively affects krill, small crustaceans that feed and find refuge beneath the sea ice, as well as fatty silverfish. Reductions in krill and fish populations affect their ...

Loss of ice in West Antarctica has been prevalent this year. In February, Antarctica sea ice reached a record low. In October, the ozone hole over Antarctica grew to one of the largest on record.

Since the late 1970s, as global temperatures ratcheted upward, sea ice in the Arctic has been swiftly declining. But in the Antarctic sea ice continued to grow into the 2010s.

Over the past four summers, Antarctic sea ice extent has hit new lows. I'm part of a large group of scientists who set out to explore the consequences of summer sea ice loss after the record lows ...

Record low sea ice Since 2015, Antarctica has displayed record-low sea ice extent, according to the study, which appeared in the peer-reviewed journal Proceedings of the National Academy of Sciences.

New research explores the wide-ranging consequences of record low summer sea ice in Antarctica. From more ocean warming to extra icebergs, it’s bad news we must hear.
