Recruiting a PhD student to work on toilet paper math. We may even start en entirely new field of mathematics. Tissue theory. Or something.

This is several layers levels of “1-book theory rolled into one. Seem slike a job for @ifbookspod.bsky.social

100% agree with this. But i worry this battle was lost when program managers at both public agencies and private foundations replaced ML with AI in the “use of … methods is encouraged” sentence.

Help! My 4 year old informed me that in her (pre-school) class they are not allowed to say “67” or “sigma”. I am by now familiar with “67”, but what does “sigma” mean???

So, #ClimateSky, solve an argument between co-authors: When writing a paper specificalyy using outputs from #CMIP6 models, do you prefer to use GCM or ESM as descriptor? #GlobalClimateModel #EarthSystemModel

My first sole-author paper is now published! 🎉🎉🎉 It's the culmination of a lot of thinking, so I hope you enjoy it. Thanks to the friends, colleagues, and reviewers who helped make this happen 😊 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

David MacKay's Sustainable Energy Without the Hot Air from 2009 had graphics such as these to illustrate the footprint of equivalent power production. Joining it onto literal land use seems a small additional step best left to the student.

Sooooooo, any climate scientists in the files?

They call this one “Adiabatically Heated Rivalry”

I've seen several Big Climate Accounts™ post about how the recent winter storm was made worse by climate change. It's a convenient narrative. s But what is "worse"? Colder temperatures? More snow? More freezing rain? Is there any primary literature supporting the idea of worse snowstorms? 1/

Also, another new book coming soon. This one much different: "Two competing meteorologists are forced to find common ground in this opposites attract, When Harry Met Sally inspired romance, from #1 New York Times bestselling author B.K. Borison." www.penguinrandomhouse.com/books/777135...

Really excited to see this paper out!! Led by @vtcoop.bsky.social we show that if you use cold and warm paleoclimates together, you can reduce uncertainty in Earth's climate sensitivity by quantifying the pattern effect and more precisely constrain future climate change www.pnas.org/doi/10.1073/...

Looking at Current Snow Depth in the Midwest. I expect the increased snow depth in Western Michigan comes from lake effect snow? But why does the South Bend metro area seem to have snow than surrounding areas? Is that a real feature, or a mapping issue? www.fs.usda.gov/sites/nfs/fi...

OK, online grocery delivery -- a first world problem, for sure, and trivial compared to the big issues like ICE in Minneapolis and Russian war crimes in Ukraine. But sometimes the small things show how F**d up the US is and highlight misdirection of society's resources. So, I've taken up a

Meanwhie, Romania is sending both its officers.

Wait. Why can't they send a married one?

And speaking of future heatwaves. New paper alert! A tour de force by my (now former) PhD student Adam Bauer. We introduce SMACM (Soil Moisture Atmosphere Coupled Model): a simple(ish) nonlinear Hasselman model to explain the non-linear relationship between temperature and soil moisture.

Good thread! Also, about that “Great Lakes/midwest as a climate haven”…. The physics of moist heatwaves is very much still an open research topic. But, as of right now, it does not look great for the midwest/great lakes region.

Anecdata on most popular texts (not in order): - Terry Pratchett (by a lot) - Far Side - Calvin and Hobbes - Science texts - Neuromancer - Hitchhiker's Guide - Lord of the Rings - Ursula K. LeGuin - A fair number of manuals of some kind. IMHO most of the jokey submissions were not very funny?

Discworld: Wee Free Men, Hogfather, Night Watch, Small Gods.

To join in the discourse of the day: If i ever get elected to office (unlikely), I will be swearing in on a copy of Terry Pratchett ‘s “The Wee Free Men”. (Or maybe Hogfather).

Dear diary, I think my 4-year old is trying to Home Alone me.

If i were a 5yo with a bad cold and fuck all to do, i would simply sleep past 5:30 in the morning.

So here is a legal/technical question: Who “owns” NCAR? Isn’t NCAR operated by UCAR, which is a university consortium? How does the govt have authority to restructure NCAR? They can defund it, sure, but how could they restructure it?

Why is there a giant empty hall with a creepy carousel in the AGU convention center? #AGU25

Assume N cubes of equal volume. What is the arrangement that minimizes the average distance between any 2 cubes? I feel like it should be a sphere (or a big cube)? What is the arrangement that maximizes that distance? Probably a straight line? This is a skeet about convention centers. #AGU25

The year is 2050 and we let Cristi organize AGU

I'll be on sabbatical starting January 1, 2026, and if anyone is looking for a guest speaker for department seminars, I'm happy to discuss possible dates. Reskeet widely! 🧪⚒️

📢Submit to our EGU session!📢 We are organizing a session at EGU 2026 in Vienna, with a focus on climate sensitivity, radiative feedbacks and the pattern effect! If you work on anything related to climate sensitivity, we'd love to have you! 🥳🥳🥳 Submit soon! :)

Dear senior profs who have written tenure letters. Can you help demystify the process for some junior profs up for tenure soon? What do you look for? How do you make your evaluation? We are told that the letters are the most important part of the file, but not what letter writers look for. 1/

So what's people favorite preprint server these days for climate science - especially in the dynamics/data-science (Stats & ML) space? ArXiv - Atmos and Ocean Physics? EarthArXiv? ESS Open Archive? EGU Sphere?

Cool paper. But they should have cited @davidho.bsky.social et al 2006 instead of Wanninkhoff 2014
