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! 🧪⚒️

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!

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.

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.

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?

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???

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
