Join AirUCI as we celebrate our friend & colleague Don Blake who received a LIFETIME ACHIEVEMENT AWARD at a VOC meeting in Guangzhou China. ⭐️🌟💫✨

Congratulations to John Mak and all of GOTHAAM. The NSF-NCAR video summary really captures the magic of atmospheric chemistry

I gave an exam Tuesday. Afterward, one student wrote to me "Professor Carlton, I loved your exam questions. You are so funny" I'm about to find out what that means exactly. 😬 Here's to being in SoCal where people are less sarcastic compared to NJ 🤞

This summer's GOTHAAM campaign to unravel the determining chemistry that affects air quality in the complex NYC metropolitan area - Led by John Mak and supported (A LOT) by NSF-NCAR Independent federal #science safeguards human health & the environment @ncar-acom.bsky.social

If you are not anti-fascist what are you?

Today, the U.S. faces one billion+ dollar climate/weather disaster on average every 2w. That's a massive increase from one every 4m in the 1980s. This is 'global weirding' and people are taking notice! The government told NOAA to stop tracking these events: but @climatecentral.org is on the job.

Thinking about my mom who taught 7 & 8th grade math. A sign in her classroom said "there are no silly questions". The guest for knowledge includes failure.

My very cute dog says no kings no tyranny… It's just common sense #nokings

A new academic year, more unprecedented things & yet we are all smiling. Go UCI! Go anteaters! 🐜🍴

University of California faculty & alumni won five (5!) Nobel Prizes in ONE week, highlighting the contributions of America’s #1 public research university & the central role of independent federal funding in advancing scientific inquiry.

In her 1964 @nature.com paper, Dr. Jane Goodall wrote about a chimpanzee using tools, challenging conventional wisdom & changing how people think. I loved her speech at Rutgers' commencement: “You are not born with a fixed amount of resilience. Like a muscle, you can build it up"

@ucirvine.bsky.social ... for real? I can't access canvas for teaching unless you have the ability to *erase all the data* on a computer I bought w/ a research grant? My personal data was already stolen at least once on resources managed by you. What could possibly go wrong? I'm literally sick🤮

There was yet another school shooting today in the United States. Compare and contrast media coverage of that with the shooting in Utah of a MAGA influencer. What do you observe?

Are you a doctoral student planning an academic career? The application deadline for the prestigious University of California President's Postdoctoral Fellowship Program for 2026-2027 is November 1, 2025. Read more: ppfp.ucop.edu/info/

I sure do play with my glasses a lot. I feel a little awkward posting this, but my Department took down the link to this interview in response to ... something 🤷🏻‍♀️ #AirQuality

Together we bargain. Alone we beg. In union there is strength. ~Happy Labor Day.

Hey @vfmcneill.bsky.social! Look at the BlueSky message from Science about the paper!

Do you believe that climate facts should remain free from political interference and easily accessible? If so, watch our video and consider supporting our initiative. Find out how you can support: donorbox.org/climate-us-p...

The last GOTHAAM flight was bittersweet and also my favorite. Measuring the trees wake up felt special.

Sometimes patience pays off... This paper has been in the works since I was still in my 30s 🤣 It was a pleasure to travel to Xian and work with @amgcarlton.bsky.social and other friends and colleagues on this

Clouds ... you love to see them.

Flax Pond is *beautiful*. You may want to check the tide charts.

Symrna, TN (L) & Islip, NY (R) Kids grow, C130s get paint jobs...the more things change, the more they stay the same. It sure would be fun to hug these two guys right now or anytime really.

NOAA has just issued a La Niña Watch for late 2025/early 2026. So far this century, we've had 12 La Niña winters versus just 8 El Niño winters. What does this portend for Southwest US drought? There's some unsettling new science out on that. yaleclimateconnections.org/2025/08/why-...

Tsunami detection in the ocean can save lives when the warnings are heeded. Improved forecasts brought to you, in part, by US scientists & engineers at NASA & NOAA @thenasaearth.bsky.social @noaa.gov

Haze from wildfire smoke from Maine to Long Island. Lyatt's chemical forecast accurately predicted this.

Indigenous peoples employed prescribed burns 🔥 as a traditional land management practice for centuries with benefits for ecosystems🌲🌸 & communities 💃👯‍♂️🧑‍🧑‍🧒‍🧒 #California capitalizes on that experience & expertise w/ this approach. There is room to grow.

This is NOT an onion article Make Gas Cans ⛽️ Great Again by Improving Flow | US #EPA In the long run they're ridding subterranean environments of harmful petrochemicals. This is actual real life #doublespeak.

Vaccines are the best way to protect against measles. Masks also help. CDC says more than 1,300 measles cases in the U.S. 🇺🇸 so far this year — the most since the virus was considered eradicated in the country. Heed the warnings!

Does anyone else feel like Fox "News" did to our parents what they thought Ozzy would do to us? Rest in Power, Mr Osborne.

The first 6 months of Trump's 2nd term have been a long 12 years. If only the other co-equal branches of government would not abdicate their power & responsibilities.

It was an honor & privilege to work in EPA's Office of Research and Development. To all of my friend's & colleagues still there, I am so sorry. You don't deserve this.

This is horrible news for anyone who breathes air or drinks water. EPA's research arm works to identify emerging pollution hazards. Ask yourself, who would be against that...🤔🤔🤔

The @colbertlateshow.bsky.social is the highest rated late night show for a while now. Colbert was just nominated AGAIN for an Emmy. #CBS can't make 💰 money💰 off of that show? It sure does sound like someone should be fired, but who?

I stand with Stephen Colbert @colbertlateshow.bsky.social

Water-soluble #science in the heat & humidity. Go team!

Microbes 🦠 & Spaaaaaaace 🛰️ Driving across the USA 🇺🇸 on my way to GOTHAAM, I collected soils samples along the way. Jude, Stephanie & I rarely get to meet in person. What.A.Treat

Project 2025 plans to break up and reduce the components of NOAA. But the services NOAA provides, every citizen uses every day.

Archimedes' discoveries, wonders & name influence centuries later. The soldier who murdered him is lost to the sands of time, like Archimedes' last scribbles. Reflecting on the US' #science ecosystem, Archimedes last words are prescient, "I beg of you, do not disturb this"

The water is boiling, frogs.

#AGU25 in New Orleans Dec 15-19 will have an excellent session in the Atmospheric Sciences section: The Agriculture-Atmosphere Nexus: Agriculture, Air Quality, Nitrogen Cycle, and Climate Connections I hope we see you there.

Trump's cuts to the Weather Service & #NOAA as laid out in #Project2025 do not help improve forecasts or save lives. Also, construction in danger-prone areas needs some local, regional and national accountability. Blame responsibly.

Professor Don Blake is a treasure and we are SO lucky to have him @ucirvine.bsky.social He is smart, generous, hard working, pleasant and funny ... I could go on. Thanks for being you, Don!

The US Global Change Research Program's website, including all its sub-domains that host the National Climate Assessments and related reports, is now offline. The 1990 Global Change Research Act (see below) mandates its research findings be available to all federal agencies & departments.

Our final updates have been posted to the Climate.gov website, and this will be our final post to our social media channels.

The Clean Air Act is VERY successful. Rolling back #EPA rules & regs is a mistake and will cost lives. The #ParisAgreement is not enough to solve the #climate emergency & also saves lives. Simon Rosanka & I take a stab at quantifying how many. Republicans attack their own best legacy 🤷🏻‍♀️

First they call you a radical socialist & then you win & then you reform stuff & then they name an airport after you:
