Excited for @cryopolitics.com and her (first) book! Privilege to be at the launch tonight - almost exactly 13 years (😱) after meeting as @scottpolar.bsky.social mphil desk neighbours.

NEW – Antarctic sea ice winter peak in 2025 is third smallest on record | @ayeshatandon.carbonbrief.org Svetlana Onye w/ comment from @zacklabe.com Read here: buff.ly/TBQ7aL8

A great couple of days at this Royal Society event on Antarctica. -Antarctica keeps surprising us -We impact Antarctica and Antarctica impacts us -Some changes are already underway but we still have a lot of agency, every .1 of a degree matters!

Polar scientists meeting at @royalsociety.org in London this week are issuing a stark warning: dramatic and extreme changes in Antarctica are happening faster than expected, with consequences that will affect everyone on the planet. www.bas.ac.uk/media-post/a...

Our book, 'The Penguin book of penguins' will be in all good bookshops as of tomorrow! We have signed some copies for Toppings and Co in Ely, Cambridge. We are having a book launch at London zoo on Sept 28. Come and find us in the Garden room, anytime between 12 noon and 3.30pm. No need to book!

Wow I've been off Bluesky for so long I forgot about the emojis If you're interested in a PhD about tracking Antarctic wildlife, consider joining my group... And, spread the word! 🧪🌍🦑🦉🦊

Average sea ice thickness across the #Arctic Ocean dropped to a record low for the month of August. Current conditions show higher extent, but very thin ice to end the summer warm season. More at zacklabe.com/arctic-sea-i.... Data simulated by PIOMAS.

When I was being advised by Ali in Chicago, I'd never have imagined we'd both end up both living and working in the north east. Look forward to you moving to the toon!

Come and join BAS, working with both MAGIC and the Wildlife from Space Team! We are looking for an expert in ecological remote sensing with experience of spectral analysis to support our Darwin Plus South Georgia Seabird project. 🐦🦤 bas.ciphr-irecruit.com/applicants/v...

I was an ICCI early career volunteer at COP28 in Dubai and I highly recommend the experience.

My latest: Polar scientists warn that the White House and NSF are planning to terminate the Nathaniel Palmer, the only US research icebreaker capable of handling Antarctic extremes, this October. So far the plan has seen minimal pushback from Congress.

🌊❄️🧪 🇦🇶 Please share: We have learned that the National Science Foundation is moving ahead with plans to decommission the U.S. Research Vessel/Ice Breaker Nathaniel B. Palmer this October. If you care about Antarctic research, please read on (1/n)

#Antarctic sea ice is: ⚙️ a global climate engine ☂️ a cooling sunshade 🌀 a pumphouse for currents 🧊 a vast verandah for life ♻️ one of the largest seasonal cycles on Earth 🌬️ highly sensitive to climate variability 🌊 What happens when there's less sea ice? aapp.shorthandstories.com/a-world-with...

Extreme Greenland melting event right now: thawing over 80% of the surface. Seen before only once in the record melt summer 2012. See more at @polarportal.bsky.social!

🚨 Our new preprint! *Cascading mass loss of Antarctic ice shelves triggered by iceberg collisions* 🔗 doi.org/10.22541/essoar.175285257.77669558/v1 In 2021, giant icebergs hit Dronning Maud Land ice shelves in #Antarctica, causing a chain reaction of calving & major regional ice-shelf area loss. 💥

Check out this time-lapse video of waves eroding an ice front from an experiment conducted in our cryogenic wave tank at the University of Wisconsin-Madison. The tank is housed in a walk-in freezer, and the waves are precisely controlled. This video captures about an hour of wave erosion.

I am co-convening a meeting at the Royal Society later this year, with @krhendry.bsky.social and other very excellent polar science colleagues. If you have interests relating to Antarctica and the impacts of climate change, please consider participating!

Great work by our colleagues Stewart Jamieson and Guy Paxman: "We have been using satellite data to map an ancient river landscape beneath the East Antarctic Ice Sheet:. The landscape has been frozen in time for up to 34 million years." ⚒️🧪 www.nature.com/articles/s41...

Don’t think anyone got a picture of me, but enjoyed representing penguins in Paris in an ANT-ICON session on marine conservation 🐧 🇫🇷

I proper love a train to a conference/workshop. On my way to the Ant-ICON Antarctic conservation workshop in Paris

Last month was the 3rd lowest #Antarctic sea ice extent on record for the month of June This was 1,280,000 km² below the 1981-2010 June average. Data from the @nsidc.bsky.social at nsidc.org/data/seaice_...

Finally: Aminat is looking for postdoctoral positions in ice sheet modeling - if you are thinking of hiring soon and looking for an experienced climate physicist and model developer, please reach out!

Publicly registering my full support for Palestine Action, while I can still do so without fear of arrest. A dark day for the country.

A good summary of the latest saga on what they continue to do to us (months and months later)... 😩 www.reddit.com/r/NOAA/comme...

What a picture

Nice piece on our recent emper penguin story: www.cbsnews.com/sanfrancisco...

On strike today with @ducu.bsky.social to protect jobs (and research and education!) at Durham University

Humans and dogs, working together. You love to see it.

Can anyone recommend a funding source for a small work package for AntarcticGlaciers focused on celebrating the role of women, indigenous peoples and minoritised people in arctic exploration? I am looking for £3-5k.

The campaign to annex Greenland has provided one of the weirder subplots of Trump’s second presidential term. Was this harebrained colonialist episode anticipated in a now forgotten novel by two modernist masters?

Breaking news: it appears Emperor penguin populations in Antarctica are declining faster than predicted. Latest satellite data shows a massive 22% drop in penguin numbers over the last 15 years in key regions. This is more than double the rate of loss that experts had expected... 🧵 1/8

Is ASF down for others? Trying to download Sentinel-1 images and get 'trouble loading search results' the last few hours. (Done it many times)

The first paper of my PhD (and my first first-author paper!) is out now in Marine Biology 🌊 🎆 We tracked snow petrels in a season of extreme weather and little sea ice in east Antarctica❄️ read more on our #ANTSIE webpage here: www.antsie.webspace.durham.ac.uk/2025/06/06/snow-petrel-tracking/

What do sea-ice associated seabirds do during a season with little sea ice? Results from GPS tracking on snow petrels is now published, led by @elliehonan.bsky.social funded by @erc.europa.eu @leverhulme.ac.uk details here: www.antsie.webspace.durham.ac.uk/2025/06/06/snow-petrel-tracking/ 🧪🐙

Nice commentary, Rose! 🌎🧪🦉🦑 insideclimatenews.org/news/2205202...

This is the third major Antarctic current potentially or actually being seriously affected by ice sheet melt. Ice Melt isn't good for sea level and then there's these downstream effects which just scale up the impact and the complexity We've learned all this in the last 3 years.

Lots of coverage of our colleague Professor Chris Stokes's research on polar ice sheets and sea level rise, here is a piece in the BBC: www.bbc.co.uk/news/article...

Hello Bluesky! 👋 This is the first post from the glaciology group at @geogdurham.bsky.social - give us a follow to hear about our icy research activities and adventures! We had a mini conference today to catch up on the brilliant range of contemporary and palaeo research by members of our group! ❄️

The strange and wonderful world beneath the ocean beneath the sea ice of Antarctica 🌊 #DMV www.theguardian.com/environment/...

We are now accepting submissions for the Annals of Glaciology special issue on 'Ice Streams and Outlet Glaciers' and welcome contributions from both palaeo and contemporary perspectives. The submission deadline is 30th September 2025, and you can find out more here: www.igsoc.org/ice-streams-...

This is horrible. I don't even know what to say. Some of our most key polar data. "As a result, the level of services for affected products below will be reduced to Basic—meaning they will remain accessible but may not be actively maintained, updated, or fully supported." nsidc.org/data/user-re...

PGC have been vital in processing and providing satellite imagery, digital elevation models, maps and other geospatial data to scientists for decades. Polar science needs this work to continue. #saveNSF #withoutNSF 🧪

😢😡

🧵🧪🌊 Further to my post yesterday about the lack of new sea ice formation in the Bellingshausen Sea (lower left in maps here), the region has now been almost ice free for more than three months. Map on left shows sea ice concentration on 1st Feb. Map on right shows concentration on 1st May.

Eek, the five emperor penguins colonies in the Bellingshausen Sea could be in trouble again.

📢 The final ArcticDEM & REMA release is here - and it might be the last. Funding cuts put vital polar data at risk. Help us rally support: take the survey! 🔗https://z.umn.edu/pgc-dem-survey #PolarScience #SavePolarData

Nooooooooooooo
