Emperor penguins officially listed as endangered 💔🐧
“further changes in sea-ice will continue to affect their breeding, feeding and moulting habitat.”

Great vid on Antarctic sea ice featuring some familiar faces (nicely done, @edoddridge.bsky.social @ariaan.bsky.social @climatenerilie.bsky.social 😃)
NEW ABNORMAL: #Antarctic sea ice on @pbs.org with @edoddridge.bsky.social @ariaan.bsky.social @climatenerilie.bsky.social & A Silvano — "the response to an extreme loss of sea ice is not just the normal response made a bit bigger, but it is structurally different."

“The response to an extreme loss of sea ice is not just the normal response made a bit bigger… it is structurally different.”
(The article currently misattributes all the quotes to Nathan - hopefully that gets fixed soon 😬)
“We don’t have to spend money on climate science if we are happy to waste it on misguided adaptation”
I decided there was no point beating around the bush when speaking with the Senators yesterday.
A group of Southern Ocean scientists giving a round of applause in sign language.
An amazing day of Southern Ocean sessions wrapped up a spectacular week at #OSM26. We leant in to the silent science disco vibe with sign language applause.
Solid advice from the botanical gardens for everyone visiting Glasgow for #OSM26 this week.
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 board might have been in the Tasman Sea this whole time, but maybe its adventure took it much farther afield. Wouldn't it be incredible if it went south and did a full circuit around world before washing up in New Zealand?!
A surfboard that was lost near Tasmania and was found, 17 months later, in New Zealand. What did its voyage look like? We can't ever know for sure, but it's fun to dream.

Predictably Woodside weren’t impressed:
"It is not possible to link GHG emissions from Scarborough with climate change or any particular climate-related impacts,"
Sure sure 🙄
New research showing climate impacts from individual fossil fuel projects. 🥵 🔥 🌏
Woodside’s Scarborough project will increase global temps by 0.00039 C and result in millions of extra coral bleaching and hundreds of extra deaths from extreme heat.
Looks like we can call it. Antarctic winter sea ice max has happened and was low, but not as low as 2023 or 2024.
Spring is arriving here in Tasmania, which means it's time to think about planting tomatoes - we can learn a surprising amount about climate change just by looking at the seasons.

Come and join us at @imas-utas.bsky.social and help build a next generation coupled ice sheet - ocean model. 🌊🧊
Are you in Hobart and looking for the perfect gift for Father’s Day on Sunday?
I can’t help you with that, sorry. But, I am giving a talk to the Royal Society of Tasmania about climate change and Antarctica. All welcome!
Sunday 7 September, 4pm, Geology Lecture Theatre, UTAS.
Oooh wow. That is excellent.
"evidence is emerging for rapid, interacting and sometimes self-perpetuating changes in the Antarctic environment"
New review out today led by @climatenerilie.bsky.social brings together the rapid changes unfolding in the Antarctic. It's powerful, and sobering, reading.
“A 1.5-foot-tall wave might not seem like much, but #tsunamis are waves that extend from the seafloor to the ocean’s surface,” said Ben Hamlington, an oceanographer at NASA’s Jet Propulsion Laboratory in Southern California." #NASA #JPL

Extreme lows in sea ice induce many changes in the physical, ecological, and societal systems of Antarctica and the Southern Ocean.
A study explores the consequences of years with low sea ice in Antarctica, including declining krill populations, warming seas, increased ice-shelf calving, and reduced access for researchers. In PNAS Nexus: academic.oup.com/pnasnexus/ar...
A line graph showing Antarctic sea ice extent anomalies for each year since 1979. The red line, which shows 2025, has just nosedived and is near the grey line for 2024.
😳
So much for the hope that 2025 might be a little less extreme.
🌊🧊
The impacts of extreme lows in Antarctic summer sea ice are confronting. Read all about it in our new paper just out in @pnasnexus.org
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."

A schematic showing many parts of the Antarctic climate system and ecosystems. Losing summer sea ice impacts pretty much all them.
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.
