I still find it mind boggling that in one of my favorite places, in Alaska, we can walk along on the bed of an ancient, water-terminating ice stream, just as we might find in Antarctica or Greenland. onlinelibrary.wiley.com/doi/10.1111/...

Glaciologists- are you aware of any literature in the last couple decades that finds Thwaites to be in a stable setting? Or even that it might not collapse? I'm not sure why we keep writing that "Thwaites Glacier _might_ collapse" Can we just all cut to the chase?

A local journalist reached out to ask about regional glacier change- one of the first places I checked was maps.theia-land.fr, a really super, interactive resource, hidden within Hugonnet et al., 2021, www.nature.com/articles/s41....

This is some bullshit “The NSF polar office has awarded 88 percent less money in grants this year.” This would take standard ~10% funding rates down to 1%. No wonder my program officer was forbidden from telling me the funding rate after we were rejected www.nytimes.com/interactive/...

My wife hears Richard Alley giving kickoff plenary at an IPY meeting, and comes down the hall to ask "Who is _this_? This person is a delight!" Talk about generational talent...

Here's the glacier intervention article that I wish everyone would lead with: eos.org/opinions/gla... Neither in thrall to the wonders of Antarctica nor absolutist in opposition, the authors illuminate the middle way and finally get right the fact that there are many many complicated considerations

Hearing all the trump news makes me think of a grad student who’s sending me a new draft manuscript every 4 hrs, with the note, “New version! Ignore the last one. Give me feedback on this one ASAP.”

I've just had two resubmitted proposals rejected by NSF's Arctic Natural Sciences. One had only two reviews (E and VG) w/o a panel summary, and one had a short note from a program officer (stating that reviews were attached) but without any kind of peer review whatsoever. Unlucky? Or NSF in 2025?

The @uidaho.bsky.social Dept of Civil and Enviro Engineering is hiring a Geological Engineer! Open until filled. I highly recommend both the Univ of Idaho, and life in Moscow, ID. Excellent research and teaching support, stellar quality of life. uidaho.peopleadmin.com/postings/46669

Ice sheet loss leads to coastal flooding- now and in the future. Unfortunately, ice sheet modelling groups haven't been empowered to reproduce observed ice sheet changes in a way that is necessary to have confidence in projections. See my #AGU24 presentation here: tbartholomaus.org/ice-sheet-mo...

This is cool. I also can't help but watch and try to deconvolve EOFs in my head

I created a starter pack on "Sea level change and coastal erosion". If you think I should add other people, please let me know. 7/x @drstrawpants.wobbly.earth @gaelforget.net @gomezserrano-ma.bsky.social @timbartholomaus.bsky.social @bhamlington.bsky.social go.bsky.app/B6spBdu

The national labs represent a fantastic model for how actionable, credible projections of sea level rise could be produced. Our country decided that building a U.S. resilient to climate change is in the nation's best interest, and natl labs could meet the need. Let's implement for sea level rise.

While useful for discovery science, work within the traditional academic structure of competition and academic prestige (through eg high-profile publications, grant dollars) significantly slows the solution of collaborative problems like sea level rise I found surprising agreement at #AGU24

Cool perspectives in the Hot Topics in Climate Policy at #AGU24. Neat to think about how best to affect change and communicate science.

Super great tool now online, shared by Denis Felikson, to make it easy to compare ice sheet model output with observations of ice sheet change. #AGU24 Will be very useful for the validation and increased confidence in the next round of projections of ice sheet change

I've really been enjoying the bike infrastructure in DC, at #AGU24. Lots of nice, protected bike lanes and the bike share systems are very easy to use.

The financial costs of the #ClimateCrisis “are now starkly apparent to Americans in the form of soaring home insurance premiums – with those in the riskiest areas for floods, storms and wildfires suffering the steepest rises of all.” “A climate crisis is starting to stir an insurance crisis.”

Here's the punchline for #AGU24: "A singular, critical mission deserves mission-focused staff" Backup and justification at my talk tomorrow afternoon: 3 pm Tuesday SY23F-05 The massive unmet need for applied ice sheet modeling in Capitol/Congress of Marriott Marquis (below ground Meeting Level 4)

I'm really excited about my #AGU24 presentation- my first in the Science and Society focus group. It reflects my growing enthusiasm for creating systematic change in the way that glaciology can meet the needs of people living on coasts.

Nice view of 15,000 yr old Lake Bonneville shorelines in southern ID/northern UT, on way to #AGU24

With glaciers worldwide in retreat, you don't typically see moraine building. But at Yahtse Glacier, during my PhD project, we got a great look at the process responsible for so many critical reconstructions of glacier change and paleoclimate. Enjoy! ⚒️🧪

The @uidaho.bsky.social College of Grad Studies reminds me that Yoram Terleth won third place, state-wide, in the 3 Minute Thesis competition last year! Yoram, a PhD student working with me, will present his latest next week in a Thurs am talk in glacier hydrology and a Wed pm poster in enviro seis

"The work of a glaciologist is almost like the work of a plumber, but you're not actually allowed to touch any of the pipes, and you have to just figure out where they are and how this plumbing system works, but without ever getting underneath the sink." Fun interview www.youtube.com/watch?v=5rCI...

Woot! Just had a paper accepted to GRL that I think is going to make a splash. 🤠 Relatively niche model, developed for small set of glaciers, actually can simply explain variations in glacier flow near-universally. I'm excited! Nice job Yoram Terleth, in colab with @glacierdoc.bsky.social

Nice to see @uidaho.bsky.social represented in the windows of the @umichlaw.bsky.social library. [Sorry for taking pictures, UM Law! It was too beautiful in there!]

Does anyone here have a good figure showing the geoscience jobs of the future, that are necessary for climate stabilization and the energy transition? We were talking energy in my intro geol class and I had a student ask me after class today. I gave her my quick answer, but I'd love a fig to share

Yay!

Congratulations to Verenis Lucas on the excellent defense of her MS thesis yesterday! Well done! And thanks to @glacierdoc.bsky.social, many colleagues at the USGS Benchmark Glacier program, committee members, and @uidaho-ess.bsky.social for making it possible.

Alaskan bogs putting on a glorious frosty display. Peatlands have cooled the climate by storing carbon that was once in the atmosphere. Protecting these natural carbon sinks is now critical so that all the hard work of peat accumulation is not undone. Protect Peat!!

Honestly, I don't really know how people whose work documents loss can manage. So bleak every time I hear about it. (anyone else find glacier mass balance sessions at AGU to be so depressing?) And my own work on glacier processes is so close to this, I really can't be surprised with findings.

Retreat of Yakutat, Alsek and Grand Plateau Glacier from 1984-2024 has led to over 100 km2 of lake expansion on the Yakutat foreland. Is this the fastest lake growth in US? @glacierdoc.bsky.social @drgilbz.bsky.social @timbartholomaus.bsky.social glacierchange.blog/2024/11/04/g...

New paper! The process of iceberg calving in Alaska is different than at the largest glaciers in Greenland, which is different than that in Antarctica. We show that up to 2/3rds of the calved mass in Greenland occurs through small events agupubs.onlinelibrary.wiley.com/doi/10.1029/... #InOtherNews

Finally, reasonable and balanced coverage of the glacier geoengineering efforts that isn't simply goo-goo, in the thrall of the efforts of superheroes trying to sweep in to save the day through tech (which seems unlikely to work and will take decades) www.science.org/content/arti...

I pulled together a bunch of my #glacier #seismology field photos from the last decade or so to share with the EarthScope Primary Instrument Center. Goal is to share ideas about station design. Maybe you'll enjoy too? ⚒️🧪 www.icloud.com/sharedalbum/...

What?! Two of Weertman's canonical works were published back to back in the same issue of J. Glac: (1) the tombstone model for basal motion (i.e., Weertman sliding) and (2) the analytical solution for an unconfined, spreading ice shelf. What a year 1957 was! Thanks for your hard work, Weertman!

I had a great last week w a really kind, dedicated group of people committed to helping others prepare for increased coastal flooding. These scientists and practitioners set aside their own needs to help build the best possible ice sheet model experiment. The scope of this effort is exciting.

I'm headed to VA to share a few thoughts with the ice sheet community community on what insurers want or need to know about sea level rise. I can only hope this slide would get the @kellyhereid.bsky.social seal of approval…

Good morning!

Always nice to see memorials to pioneering seismologists

Holy smokes- this substack is a bleak picture indeed of the present economic and community impacts of climate change. Reminds me of the beautiful and impacting novel, The Light Pirate

Highest known geophysical correlation coefficients?! Check this out: Weighing the Greenland Ice Sheet, month by month, using only GNSS stations around the margin. Essentially as good as a complicated satellite system, at least in this application. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

It’s a shame when you can date a photo by the look of the glaciers in it. Amiright, @iamdonovan.bsky.social?
