Happy Veterans Day! We don’t get Antarctic ice cores w/o skillful military air- & sea-lift. Operation Deep Freeze is important for US science & national security, world-leading in polar ops for 70 years. 📸 Ice cores loaded into an LC-130H at WAIS Divide, West Antarctica, 2009-10 season.

Hey ice sheet types! 👋 The memes about the insane number of starter packs on this thing motivated me to create one more. Please let me know who I am missing from the ice sheet world. 👇 go.bsky.app/4SxszWw

A new analysis of #CryoSat-2 data revealed that subglacial lake levels in Antarctica are changing not by centimeters but by *meters*. New research from Sally Wilson @universityofleeds.bsky.social, comments from @leighstearns.bsky.social @upenn.edu. eos.org/articles/sat...

I love how much this piece lets the readers nerd out (along with the journalist) about what processes may be at play with this retreat!

❄️ Calling all glaciology PhD students! ❄️ Applications are now open for next year’s Karthaus Summer School. It’s a great experience and you will be very well fed. Apply here: www.projects.science.uu.nl/iceclimate/k...

Trying to get more connected on here - any (other) glaciologists / snow scientists / sea-ice scientists / cryo-neds on this app that I should be following? Tag your cool friends! (Yes, that pun was intentional.)

Amazing COLDEX.org results - 6Million year old ice, with bubbles of old atmosphere. Thank you ice, for the stories you share about our planet and its climate. Led by Sarah Shakleton #glaciology #womeninstem #cryosphere #Antarctica www.pnas.org/doi/10.1073/... news.oregonstate.edu/news/six-mil...

Career update: I’m excited & honored to be @igsoc.bsky.social's new Secretary General! I’m particularly excited to return to my roots as a glaciologist in this community-facing role. As I’m getting up to speed, feel free to reach out & see you at IGS meetings and publishing in IGS journals soon?!

The disappearance of the inspiring science adventure film "For Winter" was crushing. Read the article (shorturl.at/02nDR) and... ➡️ Follow and support the amazing Alison Criscitiello ➡️ Tell National Geographic Society this is not OK and recalibrate your relationship with them. ➡️ Tell others.

And with Antarctica on top, no less. (Which is also consistent with Mātauranga Māori that I've seen presented.) I love it!

Glaciers in California’s Sierra Nevada are likely disappearing for the first time in the Holocene! 🧊😲 What a surprise! (nope) 🙃 Another evidence we are leaving the climate crucible that saw human societies develop! 🔥📈 www.science.org/doi/10.1126/...

🚨New paper 🚨@natgeosci.nature.com Greenlandification of Antarctica - comment by me + colleagues @dmidk.bsky.social @eo4cryo.bsky.social + @universityofleeds.bsky.social showing how Antarctica increasingly resembles Greenland- drawing on a mass of work from @esaclimate.bsky.social rdcu.be/eJiqJ

Will landscape responses reduce glacier sensitivity to climate change in High Mountain Asia? 🧪⚒️❄️⛰️ New paper in @egu-cr.bsky.social The Cryosphere tc.copernicus.org/articles/19/...

[1/2] Sometimes pictures say more than 1,000 words. This repeat photography of Birchgletscher (1927–2025) shows a century of change, ending in this year’s tragic collapse that destroyed Blatten and claimed one life. 📷 1927 vs 2025

In three days, our iconic red planes will take off from Canada to make the epic journey across the world to Antarctica. These flights mark the start of a new polar science season. BUT ALSO that means there's three days left to send your name to Antarctica with us! tickettoantarctica.com

More sad news for the polar community... Arctic Research Consortium of the United States (@arcus-arctic.bsky.social) is shutting down. We all lose here. The past 8 months have been unthinkable, and their consequences for the future even more so.

An excellent article in the NYTimes about the impending demise of the last U.S. Antarctic research vessel, the N.B. Palmer, featuring US and overseas colleagues (including @polarrobs.bsky.social). Gift link: www.nytimes.com/2025/08/22/c...

Left Juneau this month after wrapping up a great season with the Juneau Icefield Research Program. (So much to digest, still.) Beautiful sunrise view of the Icefield, Taku Glacier, and the landslide slope that recently fell onto South Sawyer Glacier in Tracy Arm, too!

Thanks Sarah, I know this is a focus you have had as well, and that has inspired me. We generally have 3-4 artists during the season, with overlaps. We also have repeat artists.

Woah - that’s huge!! Glad there weren’t any (cruise) ships in the fjord at the time, which is often the case!!

Juneau flood update: Officials report preliminary damage assessment of homes in the Mendenhall Valley - 6 had major damage, in the View Drive area and Meander Way. 25 homes had minor damage, 16 unaffected and 753 with no damage.

If you're a storymap kind of person, here's one that nicely explains what's happening & why with the glacial lake outburst flooding now underway on the Mendenhall River near Juneau. #akwx #ClimateChange #Flood #Glacier @spiraledu.bsky.social @alaska.bsky.social storymaps.arcgis.com/stories/72ce...

BEFORE/AFTER the South Sawyer Glacier landslide on 10th August! This HUGE event was detected by seismic stations over 1000 km away and triggered damaging tsunami waves up to 3-4 meters in Endicott Arm! 🌊 Via @geomorphyuggs.bsky.social

A huge basin of rainwater and snowmelt dammed by Alaska’s Mendenhall Glacier has started to release, and officials on Tuesday urged residents in some parts of Juneau to evacuate ahead of what could be a record surge of floodwater downstream.

Excellent Earth and sustainability themed book recommendations from @stanforddoerr.bsky.social faculty (some from yours truly) Can’t wait to read some of these! w/links to check them out from the library sustainability.stanford.edu/news/25-book...

Awesome video about a cool run. The people-focus (yes!!) reminds me of a (much shorter) run I did for my 37th birthday (37 miles, Taconic Crest Trail), with friends joining me for (almost) the whole run. Check it out www.youtube.com/watch?v=Nd0X... - thanks @semi-rad.com for the newsletter highlight

The thing about the massive reductions-in-force coming after the SCOTUS ruling today is that so many federal workers have already left - the ones remaining have been holding things together with duct tape. I don't know if folks appreciate the level of federal dysfunction heading our way.

A tough reality to see, especially after having had the privilege of going hiking in the region last summer.

First time writing a paper in a while, but I've been mulling this question for a while - when is a glacier no longer a glacier, and why do we care? Not the cheeriest, but important. @igsoc.bsky.social's special issue on Vanishing Glaciers was the perfect "excuse" to actually write it up!

Call for IGS EGG Conference Grant July 2025. All interested researchers are invited to apply for Grant. Check our website to see the eligibility criteria: igsegg.org/egg-events/con…#grantn#ecrc#igsg#conferencec#cryospherere

Yes, and look at the details. Logistics are mostly preserved, but the polar science budget is proposed to be cut 71%

📺Closing out @wclivestream.bsky.social's 💯-hour Weather & Climate Livestream: 📣 Join Climate Central's @zacklabe.com at 4:15 ET/1:15pm PT for an in-depth chat covering “Science in Retreat: The Consequences for the Arctic and Our Planet” 🎥 Watch LIVE here ▶️ www.youtube.com/@wclivestrea...

Since this is getting some reposts, those 100+ scientists are coming as part of AGU's Days of Action, and there will be many more opportunities to learn how to advocate for strong science policy with our legislators: www.agu.org/Science-Poli...

To polar research colleagues looking at NSF FY26 budget breakdown - while tempting to be relieved that Polar is less cut than others, I hope we remember how all of science must advocate together. Important research questions need interdisciplinary support and broader science participation!! #saveNSF

75% loss for education at NSF. That'll for sure help make American science great...WTF are these people thinking? 🧪 My thoughts here: theconversation.com/unprecedente...

This proposed budget is a policy statement, not an appropriation. There are still a lot of steps and potential changes ahead before it becomes one. This is not a time to sit quietly, team. Let's go.

Agree...we all should care that American science support, which made this country great, is being ripped apart in mere months. People across the political spectrum need to speak out and there will be an uproar.🧪 theconversation.com/unprecedente...

Members of congress do care about the US National Science Foundation. So should every one of us! Call your representatives. 🧪 theconversation.com/unprecedente...
