NEW: Extraordinary footage has emerged of the huge tsunami that hit Russia’s remote Kamchatka peninsula after the 8.8 magnitude earthquake on July 30th. (🎥 Doni Nikz)

🚨 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. 💥

Please share with teens or anyone you know who work with teens! #girlsinstem #glaciology #sciart #womeninstem #science this program is for teens willing to challenge themselves (**not** for just top performing students - we are open, no need to be a science or art geek either, just willing to try)

A new gigantic outburst flood from Catalina lake in East Greenland [Catalinadal, Renland, Scoresbysund]. total volume: 3.4 km3 peak discharge: ~7200 m3/s top-10 #GLOF in terms of both numbers. previous outburst 2013 I'm sending out a press release today about it. 🧪❄️ 🥼❄️ 1/x

The Snow4Flow concept paper is out! See notice in cryolist from Thursday. This will form the basis for the later AO. Stickers at #AGU24. snow4flow.lpl.arizona.edu/concept-paper

In work I’ve been quietly doing, many dozens of people’s stories & early writing drafts, one thing’s increasingly clear. “Safety by Exclusion”—the dominant paradigm in polar science & most geosci sub-fields—isn’t just harmful, it’s ineffective. It DOESN’T WORK! Makes everyone less safe, in fact. 🧪⚒️

🧪 Well-meaning arguments to “keep science apolitical” just cede the far-right-wing propaganda framing that science… • “used to be apolitical”, • “recently became politicized”, and ∴ • “needs to be fixed.” Which is 100% bullshit on every single point. Don’t do their propaganda for them.

Listen to a new episode with @joemacgregor.bsky.social on mapping Greenland's geology below the ice. An impressive story of synthesizing decades of geophysical seismic, gravity, and magnetic surveys together with radar and laser altimetry. Newly discovered: long valley networks, 3 new provinces.

Lots of new people here so a reintroduction: Glaciologist & geophysicist. Big fan of ice, especially the grounded form, at both poles. Keen on radar sounding, airborne & satellite remote sensing, & developing better boundary conditions for ice flow models. Sometimes I meme, other times I exercise.

Hi newskies - if you're interested in climate risk, and you don't follow @scrawford.bsky.social, you should probably fix that.

The first circular for the IGS Symposium on Ice Streams and Outlet Glaciers is out now! ❄️ We have some fantastic invited speakers lined up and are looking forward to welcoming you to Durham in July 2025. Check out the circular and register your interest here: www.igsoc.org/event/ice-st... ⚒️🧪

Carbon capture and storage is designed to capture government subsidies, not carbon.

Field scientists and those that approve expenses like wilderness first aid and crevasse rescue courses, READ THIS from @snowhydro.bsky.social: www.nature.com/articles/d41...

Paleoclimate constraints on the future of El Niño: congrats to @carbon8.bsky.social and all the coauthors www.nature.com/articles/s41...

I highly recommend @scrawford.bsky.social's newsletter, which I think @kellyhereid.bsky.social clued me in to. Always informative and insightful into ongoing adaptation strategies and challenges associated with sea-level rise.

Check out a new multi-agency effort on sea level rise for the US. Updated observations and projections including vertical land motion impacts. sealevel.globalchange.gov

Scientific American gave a brief intro of our new map of Greenland’s subglacial geology — “Complex, Hidden Landscape Mapped a Mile under Greenland Ice” — led by @joemacgregor.bsky.social www.scientificamerican.com/article/comp...

Greenland was warm enough, for long enough, for an entire tundra ecosystem where today ice is two miles deep, during an interglacial within the last million years 🧪⚒️❄️ phys.org/news/2024-08...

Oh hey, this is finally public! I've been working for a bit with the GMAO folks at NASA GSFC to leverage the near-real-time capabilities of GEOS-FP in combination with the robustness + length of record of the MERRA-2 reanalysis. Last week was hella hot, y'all! www.nasa.gov/earth/nasa-d... 🧪⚒️

Hey All! We're looking for a glaciology PhD student at DTU-Space to model the ice flow of the Greenland ice sheet over the past 12,000 years. 👇 efzu.fa.em2.oraclecloud.com/hcmUI/Candid... The CISP team is fun and growing! This call closes 16 August 2024.

This is poor/confusing framing for several reasons. Among them: We ARE measuring sea-levels now and have been for decades, and NOT with Terra/Aqua. It's painful to lose them, but for detecting ice-shelf collapse, there are other satellites with comparable ability. www.nytimes.com/2024/05/03/c...

A nice summary in Eos of our new GRL article on Greenland's subglacial geology eos.org/research-spo...

Cool forest canopy dataset from... Meta. sustainability.fb.com/blog/2024/04... Map: meta-forest-monitoring-okw37.projects.earthengine.app/view/canopyh... They want to use it for... carbon offsets. I want to use it for... wildfire risk! biodiversity risk!

We've got recordings of essentially all public presentations and discussions from the recent Future of Greenland ice Sheet science workshop, now up and available to stream via www.fogss-workshop.org/2024-agenda Check it out! Talks from NASA, NSF, and leaders of major initiatives to inspire action

Snow4Flow LET'S GOOOOO! So excited for this. www.nasa.gov/news-release... Also it's Mara's birthday

🚨 It's not everyday that Greenland's subglacial geology is updated. Check out this very fat brick in the road towards resolving Greenland's under-ice geology! 👇 news: eng.geus.dk/about/news/n... article: doi.org/10.1029/2023... data: doi.org/10.22008/FK2... led by @joemacgregor.bsky.social

There's a lot going on in this excellent article, and way to go his brave students for standing up to this toxic mentor, but Dr. Dias' collaborator review timelines are hilarious.

For the glaciologists

Draft agenda is up for this spring's Future of Greenland ice Sheet Science workshop! Registration link later this week. Gonna be a fun and exciting workshop! www.fogss-workshop.org/2024-workshop

Come join us in Moscow, ID, April 3-5, for FOGSS! The Univ of Idaho is in a gorgeous region and several local airports make travel surprisingly easy (maps.app.goo.gl/YqvR58KcHVMb...). To learn more about FOGSS or subscribe to our mailing list, check out www.fogss-workshop.org/2024-workshop

"NSF has stringent protocols to keep personnel safe from risks like frostbite or wandering off in a blizzard. It has strict regulations to ensure wildlife live undisturbed. But it’s only recently that the agency has started to tackle sexual harassment and assault within its Antarctic workforce" 🧪

You may be surprised to find that I, a climate person in insurance, find a lot to like about this article. Tl;Dr We haven't made hard choices in adaptation. Insurance is a symptom. Wish I could compose threads in advance here, but instead you'll get some stream of consciousness reactions 1/🧵
