What is even the point of global warming if swimming pools still don’t open before Memorial day?

I may have signed up to think about how to build a more general climate model emulator.

This seems suboptimal

Playing around with some visualizations around corn and biofuels for a Climate Change 101 summer class.

After 4 days in the Kansas City metro area - a fast growing metro with the same population as Bucharest metro but 10-15x the surface area - i keep coming back to one depressing thought: Anyone hoping for mass adoption of public transport in the US is detached from the reality on the ground :(

Had a scenic 11 hour trip back home from Kansas today. Two things that are nearly impossible to find outside major cities: 1. A men’s room with a baby changing table 2. A vegetable that is not pickled or deep fried.

What did I miss? Why are we doing RCP8.5 discourse again? (Honest question)

Have you ever read the Sherwood, Webb et al 2020 assessment of ECS and thought "I'd love to play with the numbers if only it didn't take 1 day to sample the posterior?" Rejoice! I've implemented the model in @mc-stan.org, and it now runs in ~1 minute. You can even run it in Google colab: 1/

Look, i’m not saying that the CMIP model-obs discrepancy in EEI is not a thing. All i’m saying is i lived through the Hiatus.

If you’re at EGU on Monday come see my talk on what controls the Zero Emission Commitment, i.e. how much warming we can expect once we cease all emissions. Some nasty surprises may await. ` *Monday May 04, 09:55-10:05, Room 0.49/50 (Session CL3.2.1)* meetingorganizer.copernicus.org/EGU26/EGU26-...

New project underway! "Here be dragons: Mapping terrestrial carbon cycle tipping points under joint SAI and carbon emissions" I feel very lucky that Reflective decided to fund myself, Prof. Hannah Horowitz, Prof. @ecoclimatelab.bsky.social and Graduate Student Summer Acker to work on this project!

The largest post-glacial meltwater pulse occurred roughly 14,000 years ago. It likely originated in what is now Canada, which is why it is called “Meltwater Pulse 1,eh”

New preprint up: Optimizing Objective Model Calibration Approaches using Single Column Models. Comments welcome. Can PPE+ML calibration methods recover model parameters in a perfect model setup? We test this out with the Single Column Atmospheric Model (SCAM) and some synthetic data.

The debate continues: Multidecadal variability in the Atlantic mostly forced, multidecadal variability in the Pacific mostly internal agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Most of my career has been in area of climate science called "the pattern effect". Work over the last decade (including my own) has led to a simple paradigm for the mechanisms of the pattern effect. In this new preprint, we argue this paradigm is woefully insufficient arxiv.org/abs/2603.24488 1/

Back to basics: if we want to understand the pattern effect we need to think about wave dynamics

Geomorphtweeps - does anyone know of a bedrock canyon being carved by a single flood event? I know Mike Lamb @caltech.edu has published on some (Box Canyon and Canyon Lake Gorge) but are there others? Reskeet widely! 🧪⚒️

Painting in my local coffee shop.

Huh? There’s a PNAS Communications now??

Not the main point, but did OU put in it’s own proposal or not? I’ve heard conflicting reports

Watch this space! More boron-ice comparison in the pipeline. I think 2026 will be a good year for past CO2 & at least my "hot take", we're not so far apart. Super happy to see this challenging data from the blue ice. Let's not forget that just finding it is a feat, & a data point all of its own!

New Scientist write-up on the new Blue Ice results. www.newscientist.com/article/2519...

Oh and looks like @climateofgavin.bsky.social just came out with some nice additional context.

Getting direct measurements of CO2 from Pliocene-aged ice has been a Holy Grail of climate science! A new paper by @jmarkspeterson.bsky.social provides a record of CO2 going back 3million years(!), with (let's say) intriguing implications for anthropogenic climate change doi.org/10.1038/s415... 1/

I’m doing my climate science and social media lecture again. Anybody seen any good astroturfing examples recently?

At this point, I'm pretty sure I'm just having a conversation with ChatGPT... (edited to remove identifying information) The humor of this exchange aside, all of this is probably wreaking havoc on grad admissions. I wonder what the Kalshi odds are for "Graduate schools bring back GREs before 2028?"

It was the winter of despair, it was the summer of despair

It was the worst of times, it was the… yeah, no, it was just the worst of times.

Wow, that's a monster signal for El Niño in today's new ECMWF seasonal forecast.

4 year old, making a lego soccer stadium: “The girls’ team is called the ponytails. The boys’ team is called the pockets.” “Why?” “Because girls have ponytails, and boys have pockets”

In all my years in academia this is the closest thing i’ve seen to a faculty lounge. (5 people will find this funny)

I’ve never even seen a faculty lounge. Nor have I ever seen a faculty lounge.

Agent working through a problem.

HR is preparing a new “AI professional development” training series. It has two separate tracks. So now I have to figure out whether HR thinks of faculty as “staff” or “leadership”. chat, what do you think?

My contribution to the rice discourse is that , having grown up in the balkans, i was 18 years old when i found out you can eat rice in any form other than pilaf

The best map i’ve seen all year. And i work in a job where most of what i do is stare at maps.

Making the answer to every question on the first homework be some version of “67” is a good way to ensure your students stop saying “6-7” for the rest of the semester. E.g. “Fill in the blanks: the Stefan-Boltzmann constant is 5.__x10^-8”

if you're an older person who finds words like mogg and maxxing annoying, just starting using them. people over the age of 30 have the superpower to end trends by simply adopting them

My favorite part of doing peer reviewed research is when the response to reviewers on a "MINOR revisions" is longer than the manuscript itself....

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???
