This is so, so well-articulated.
People call this friction "grunt work." Schwartz uses exactly that phrase, and he's right that LLMs can remove it. What he doesn't say, because he already has decades of hard-won intuition and doesn't need the grunt work anymore, is that for someone who doesn't yet have that intuition, the grunt work is the work. The boring parts and the important parts are tangled together in a way that you can't separate in advance. You don't know which afternoon of debugging was the one that taught you something fundamental about your data until three years later, when you're working on a completely different problem and the insight surfaces. Serendipity doesn't come from efficiency. It comes from spending time in the space where the problem lives, getting your hands dirty, making mistakes that nobody asked you to make and learning things nobody assigned you to learn.

I had a feeling this was going to happen. Sad news, especially given the poor state of sea ice after this winter. Looks like we won't be getting any more data for Arctic sea-ice thickness and volume for a while from PIOMAS. See: psc.apl.uw.edu/research/pro...
Screenshot of text that says: "Important Notice (3/24/2026): 
NOAA NWS/NCEP has terminated the NCEP/NCAR R1 reanalysis as of March 18th, 2026. NCEP/NCAR R1 has been used as the atmospheric forcing data in the PIOMAS reanalysis . We had not been aware of this change in service which was apparently formally announced Feb 13. 2026. This means that we will have to find alternatives and generate a replacement. It will take considerable effort and time to update data streams, re-calibrate the model and generate updated time series. We don’t yet have a good sense if that’s possible with available funds and if so, when we will be able to resume production of a new PIOMAS time series. While a replacement of the NCAR/NCEP R1 as the forcing product makes ultimate sense, we would have wished for a longer time period to facilitate the transition. We are sorry what this means to our many users.  PIOMAS has been in production since March 2010 and we rarely missed updates by more than a couple of weeks (except for  government shutdowns). This will be longer. Check back here for updates! "

I agree. This event has been meteorologically astonishing, and its impacts will be felt long after it ends in terms of record low snowpack, sharply increased wildfire risk, and extreme low watershed runoff/streamflow into summer and beyond.

In landscape ecology, I emphasize how simple models can illustrate complex patterns—like how dispersal on an environmental gradient can look like species sorting and niche partitioning. So, I make toy models for class.

You can see the history of the landscape everywhere: An oak that probably grew in a pasture with scattered trees, likely savanna before that, now surrounded by younger trees. Within sight of our house, which sits close to the edge of open prairie on the 1830s public land survey sketch map.

1,000 inches of snow? It's possible on the USA's snowiest mountain.
The “snowiest” label could depend on whether you’re talking about where the most snow falls or where the most snow piles up.
