cool- thanks! I hadn't seen that one. So perhaps if the present ACC temperatures are a transient warming, which then passes, then they can all recover..?

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/...
Trump Has Cut Science Funding to Its Lowest Level in Decades
The lag in funding extends far beyond D.E.I. initiatives, affecting almost every area of science: chemistry, computing, engineering, materials and more.

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...

But I guess, if the main point is that "it's complicated," it's a small wonder that I hadn't yet encountered this essay. Where's the fist shaking?!

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

Although in retrospect, I realize part of the reason this was so popular is that it was a break from otherwise wall-to-wall covid coverage.

For more bewildering coverage of the highest impact work I’ll ever do, I tried to track it here: tbartholomaus.org/media/#:~:te....
Meet The 'Glacier Mice' : Short Wave
(Encore episode.) In 2006, while hiking around the Root Glacier in Alaska, glaciologist Tim Bartholomaus encountered something strange and unexpected on the ice — dozens of fuzzy, green moss balls. It...

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.”

Have you gotten any reviews back recently? Anything out of the ordinary?

I remain committed to my work of understanding glacier behavior, in order to empower community responses to catastrophic flooding. But I'm not sure how to proceed in this mix of not enough and too much information
timbartholomaus.bsky.social
Any other recent experiences NSF experiences out there I can compare with?

There were glacier proposals, and according to 2024 best practice and current NSF guidance (www.nsf.gov/funding/lear...), we wrote "The team is dedicated to increasing diversity, equity, and inclusion in cryospheric science"

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?

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

Here's the 2024 Daily Average Temperature anomaly for the contiguous United States.

Stay tuned for the official update from NOAA/NCEI this week to see where this ranks against the period of record (1895-2024).

Be in touch if you have questions or want to discuss more.

The first step to addressing this problem is identifying and communicating the problem.
timbartholomaus.bsky.social
This problem stems from the novelty of the research in this area and the legacy view of ice sheet modeling as an academic curiosity. Now that there is a clear applied need for ice sheet modeling to inform coastal planning, there needs to be a funding program to meet this need.
timbartholomaus.bsky.social
Because the simulations of observed ice sheet change are so flawed, the projections of sea level rise are likely flawed similarly. This means the funding going towards protecting coastal communities is potentially misallocated- it may not provide the level of protection for which its designed.
