The odds are pretty low (infinitesimal really), but we'll never know. And maybe it's better that way; after 17 months at sea, I think that surf board has earned the right to keep its secrets.

The speed of change that led to previous mass excitations is terrifyingly slow compared to modern change 😳 "In the case of the Permian–Triassic mass extinction, plants were unable to respond on as rapid a time scale as 1,000 to 10,000 years. This resulted in a large extinction event."

The environment and ecosystems around Antarctica are a complex tapestry of interconnected systems. We've tried our best to think about all the ways that losing summer sea ice will impact our climate, ecosystems, and society. The answers we found were confronting.
A schematic showing many parts of the Antarctic climate system and ecosystems. Losing summer sea ice impacts pretty much all them.

Even humans use the sea ice as a platform. This photo shows the Australian icebreaker, the RSV Nuyina, parked in the ice for a resupply mission. Less summertime sea ice will make it increasingly difficult to resupply Antarctic bases like this. 📸 Jared McGhie (AAD)

Lots of the wildlife around Antarctica depends on sea ice. These Adelie penguins are sheltering on a piece of sea ice while they moult and replace all their feathers. Low sea ice will make it harder to find shelter and expose them to predators.

Ed Doddridge @edoddridge.bsky.social · 02/07/2025
More icebergs means the ice shelves are losing mass faster, but even more importantly, our climate models don't include this affect, so we're probably underestimating how fast the sea level will rise in the future 🌊

Sea ice also protects the Antarctic margins from wave damage. We found twice as many icebergs break off in summers with low sea ice. 📸: Pete Harmsen (AAD)

What's Antarctic sea ice ever done for us? Quite a lot! It cools the ocean, protects ice shelves, supports an irreplaceable ecosystem. Oh, and helps the ocean absorb $180 billion of carbon per year. Hopefully we can figure this out whilst there still is some summer sea ice... doi.org/10.1093/pnas...
