The Auto Industry Was Warned: Battery Recycling Was Poisoning People www.nytimes.com/2025/11/25/w...

Some exciting news to share: very soon, NOAA Research will be hiring new federal employees into science positions across the agency! A couple of notes: 1) They will only be open on USAJobs for seven days. 2) Multiple positions at different sites may be in one posting. (1/2)

So loads of people are sharing an obvious ai "glow up" of an actual photo. I never share ai stuff even to dunk, but in this case I'm sharing a comparison to show the problem. We have to stand against this slop at every level or it becomes normalised. They want us to stop caring. See alt text.

The hot in the west was hotter than the cold in the east was cold. #climatechange

Data centers can play nice with the grid if they come with battery storage. Tesla has done a good job highlighting this in their Megapack materials. What will it take for this to be more widely known?

Incredible work from @caltechlcssp.bsky.social Board Member, @cfranken.bsky.social, @caltech.edu and @nasajpl.bsky.social! For more information - github.com/RemoteSensin...

AGU mourns the passing of Michael McElroy, a towering figure in atmospheric and climate science. His six decades of research helped shape global environmental policy and inspired generations of scientists. His legacy will endure. buff.ly/KCHS5Mb

"The global benchmark cost for a four-hour battery project fell 27% year-on-year to $78 per megawatt-hour in 2025, marking a record low since BloombergNEF began tracking such costs in 2009." www.businessgreen.com/news/4525816... via @stuartstone.bsky.social 🔌💡

40 years of forest soil lead shows automobile Pb has decreased but still present across the northeast US. Very happy to have published this work with great colleagues link.springer.com/article/10.1...

"When staffers at the air district reached out to a small sample of people to verify their comments, at least three said they had not written to the agency and were not aware of any such messages, records show."

I am heartbroken to learn to George Rossman has passed away - George was not only a brilliant chemist turned geoscientist, but also had an exceptionally good taste in methods - Raman + FT-IR spectroscopy - and cookies ... [1/3] www.gia.edu/gia-news-pre...

Such a great colleague. We bonded over our common interest in FTIR spectrometry (and other things). His memory is a blessing. www.caltech.edu/about/news/c...

Passing along the news to the geology community. ⚒️ During my time at Caltech, I could always count on George for friendly greetings, a positive attitude, and odd yet delightful remarks. www.caltech.edu/about/news/c...

If you're ever wondering why Los Angeles is so dysfunctional, one reasons is that there's a whole ecosystem of groups like this that are funded by taxpayers (!) and big, old-money foundations that are asleep at the wheel. From @resnikoff.bsky.social: www.insidephilanthropy.com/home/philant...

Be a hero @nytimes.com, hire the @capitalweather.bsky.social group.

Congratulations to Hongmin (Maria) Yu who successfully and expertly defended her thesis "Exploring Atmospheric Autoxidation of Organic Emission from Volatile Chemical Products". Thanks to @jessekroll.bsky.social, and @caltech.edu Profs Mitchio Okumura, and Rick Flagan for serving on her committee.

Yesterday it was cows using tools, today its penguins using satellite imagery.

New analysis of air quality data from the past 70 years by Robert Field, Olivia Clifton, Konstantinos Tsigaridis of NASA GISS and co-authors shows that Canada's record wildfire smoke in 2023 is part of a broader, continent-wide trend toward smokier skies: https://bit.ly/3NSuXro

Co-editor @traciemaddy.bsky.social and I are excited about this book and the opportunity to work w/ you!

Pretty much.

The kids are alright

Yes, the city needs to actually repave streets. Yes, the city needs to repair sidewalks. Yes, the city needs to install curb ramps. But the bigger problem is that when LA decides to do anything at all to "help" pedestrians, the result looks like this complete and utter bullshit

Long Beach was one of 6 cities that was included in a state bill to allow a speed camera pilot program. Despite cameras now being operational in San Francisco, Long Beach has yet to make any meaningful progress towards the rollout of actual cameras.

Wyoming and Mississippi are such outliers.

Do you believe that today second hand smoke concerns would bring down the US tobacco industry? Or would such arguments be turned aside as ‘woke mind set’? Do arguments focused on public health still resonate?

I spoke with @carlzimmer.com about our terminated grant on wildfire smoke and homes:

What a loss that @marinavance.bsky.social's EPA-funded research on wildfire smoke in homes has been canceled! I remain a proud academic mom. She did her PhD on exposure to engineered nanoparticles @virginiatech.bsky.social, right as my lab was shifting to study viruses in the air.

Merry Christmas, Birds.

I’d like to audit this.

Climate is complicated. 0.2 increase over 3 yrs contributed significantly to the acceleration in surface warming in the recent past. Fortunately temporary.

$50 million commitment to Caltech endows and names the Lynn Booth and Kent Kresa Department of Aerospace, securing the Institute's leadership in the rapidly evolving sectors of space science and exploration. Read more: bit.ly/456iTZt

Astronomers are reporting evidence for a possible second kilonova event, but the case is not closed. In fact, this situation is much more complex. www.caltech.edu/about/news/p...

Improvements in public health have been the source of most of the reduction in morbidity and mortality. It seems a lesson that mostly falls on deaf ears in the US where most of the investments flow to research on genetics and gene therapy.

Uggggly.

Incredible story. www.nytimes.com/2025/12/07/b...

Classic commons problem. A revenue neutral contrail tax would be an efficient mitigation strategy I think.

The last - but certainly not least - instrument on board Metop-SGA1 to share its 1st images has now delivered! Data from #Sentinel5 was unveiled today at @esa.int's Ministerial Council where EUMETSAT joined ESA & @ec.europa.eu to showcase Earth's air quality from space: bit.ly/4rnIRBi 🧵

Made me laugh

Today on Volts: for years, I've wanted to do a podcast on indoor air quality, and I finally found the perfect guest! Dr. Lagoudas & I discuss indoor air pollutants, the policies and technologies that can control them, and the growing need to frame indoor air quality as a basic human right.
