Unfortunately you don’t get this kind of discourse on blue sky

If an AI weather model missed that a hurricane would strengthen to a some hypothetical unseen Cat 6 instead of Cat 5 but still got the timing broadly right (cheaper and faster), would it really matter ? www.bloomberg.com/opinion/arti...

It’s amazing that LinkedIn posts were like that before llm’s

And to think this doesn’t even get to AI stagnating our culture open.substack.com/pub/experime...

I wrote about Rosalía's "Lux," martyrdom, and our collective gastrointestinal health johnpaulbrammer.substack.com/p/eat-me

Seems not great

Trudeau/Katy Perry, Louvre heist… this is the type of shenanigans reporting that we don’t get anymore when the news cycle is all fascism and horrors of AI

Our new article out today takes a hard look at some practical limitations on stratospheric aerosol injection and what they means for the riskiness of this approach. @mcneill-lab.org w/ @gwagner.com & @steingart.bsky.social @climate.columbia.edu @columbiaseas.bsky.social Here's the press release:

Every few months now I re-read this "Who Goes Nazi?" piece from 1941 and am blown away by how it captures the people we are dealing with 80 years later. harpers.org/archive/1941...

Celebrating Richard Flagan's 50 years of service to @caltech.edu! Rick arrived in 1975 intending to study combustion chemistry and ended up playing an enormously influential role in developing new instrumentation to quantify atmospheric aerosol and helping to mitigate air pollution in LA and beyond.

This is one of the most beautiful things I have witnessed, the craft here is impeccable.

They should read our new study. In Los Angeles Purple Air sensors are likely more accurate than the expensive sensors. www.science.org/doi/10.1126/...

This work was really fun for us (I think) and also shows a lot of our biases. We’ve been so focused on organic aerosol the past decade (at least in LA), that when we saw that the nitrate component was more abundant than the organic, we had to unearth the ancient texts on ammonium nitrate

Coming across your paper, @ryanward.bsky.social is an excellent twist of fate.... I ❤️ your work! Congratulations.

from across campus in the rain I can hear a chorus of boo’s at Columbia commencement

The thought of Lori lightfoot having met the pope

a lot of discourse about AI destroying student creativity and critical thinking paired with a perhaps ironic lack of creative solutions

I don’t like the press knowing what read only means

With AI about to render a lot of industry jobs obsolete (decadal time horizon) and the federal gov’t looking to nuke your field… good time to plan a career

Written 18 years ago. from Twilight of the Superheroes by Deborah Eisenberg

A Santa Ana wind can flush out the PM almost entirely from the LA basin. And in the presence of strongly wind-driven sources, it can generate unprecedented PM. Of course, the bigger health concern is getting everyone at the urban-forest interfaces out. Hoping everyone stays safe😪

This will be one of the all-time work-ending social media events of my lifetime

Has isoprene not given us enough… let her rest

Relevant for like 3 ppl: upon inspecting Science Advances info for authors, there was very coincidentally an example citation for a paper I have recently spent a lot of time with, and ironically the example citation is wrong💀 Should be I. N. Tang (respect to atmospheric science legend Ignatius Tang)

Important points from Brian Deese. We need a national strategy for AI and energy demand. Both to ensure we maintain progress on decarbonization, and also to make sure we build the infrastructure we need to stay competitive internationally. heatmap.news/technology/a...

Things are unfortunately getting very real

THE PROBLEM: Most forms of energy are harming the environment THE SOLUTION: Switch to alternative forms of renewab... THE PROBLEM: Hold on, I have an idea, what if we made invisible valueless money that eats electricity THE SOLUTION: ...what? THE PROBLEM: Also I have this plagiarism machine

Learned about a lake the size of Burkina Faso today😵

Random used book store find to discover caltech had a department of meteorology in the 30s/40s run by a con artist… what’s that saying about street vs book smarts
