Are you concerned about mercury? πŸ’‰
POTUS ordered the Pentagon to buy more coal for electricity generation. If that happens there will be more mercury in the air & then in your lungs. 🫁 That kind of mercury toxin harms you & there's no way to get better.β€οΈβ€πŸ©Ή

60 Years of ES&T: Aerosols and Atmospheric Chemistry

Happy 60th ES&T! πŸŽ‰πŸ₯³πŸŽˆπŸŽŠ

Our take on ES&T papers and how they've shaped and influenced our understanding of atmospheric chemistry.

Lead in archived hair documents a decline in lead exposure to humans since the establishment of the US Environmental Protection Agency | PNAS Lead (Pb) is well known to be toxic to humans. We use archived hair from individuals living along the Wasatch Front in Utah to evaluate changes in ...

Trending #PNAS article: #EPA starts regulating lead & [Pb] in humans decreased A LOT (note: log scale). This decrease is associated with children's increased IQ score. EPA wants to protect YOU from poison in the air & water. It's worth asking who would be against that. www.pnas.org/doi/10.1073/...

Imagine thinking the lack of patience for careful introspection and contemplation & inability to carefully articulate are skills worth bragging about. Infants cry out when their feelings are hurt....

Robot in "nature".
Irvine is using robots to survey parks and asks that you treat the robots like an actual city employee. I wish it was an actual humanoid city employee.

There's an exam Friday & my office hours are standing room / floor sitting only. Do you notice a pattern? The privilege of working with bright young ambitious people.

For the first time since I moved to CA, I was able to see Los Angeles (~30 miles) from a vista in my neighborhood. Not the first time I could see pollution haze.

Financial sustainability depends on *trust*: keep the πŸ’‘ on, diversify revenue. Be clear about priorities & protective of the core academic mission. Don’t trade long-term credibility for short-term relief. Values aren’t what make universities fragile, its what makes them great long-term investments

A tragedy of academia during that time was not that Universities lacked brilliant people. It was that some forgot what they stood for. Do not abandon your standards.

Practical modern applications:
1.) defend process not outcome (free inquiry, peer review, due process)
2.) protect the vulnerable
3.) avoid fake neutrality when academic norms are ar stake
4.) resist political capture
5.) articulate why Universities exist beyond markets & politics

Their commonalities:
1. Defended academic freedom (even when unpopular)
2. Exhibited moral clarity w/o partisan capture: legitimate debate vs. ideology
3.) Internationalism
4.) Resisted Instrumentalism (no job training centers or political messaging arms)
5.) courage during uncertainty

During the interwar period (c. 1918-1939) universities were in economic crisis, rising authoritarianism, ideological polarization & global instability. Sound familiar? What did successful academic leaders do? πŸ§΅β¬‡οΈ

Save NCAR from being dismantled today! The Trump Administration has vowed to dissolve the center that provides critical extreme weather and climate data for our nation.

Are you an atmospheric scientist? Do you like knowing where smoke and other plumes go & what harmful chemicals might be in those plumes? Then you value NCAR even if you didn't know. Take a moment to tell your Rep and Senators, please: agu.quorum.us/campaign/151...

CondΓ© Nast owns Vanity Fair & its late owner promoted Art of the Deal … sure it’s a hit piece if by that you mean a well timed, carefully crafted article distracting people with fluff they already know.

The NSF resources being 'divested' helped us discover how 'biogenic' particulate matter is actually controllable pollution.

I am really proud of AGU.
Want to write a review article? May I suggest Reviews of Geophysics.

Of course this experiment has been done before in other cities, and yet a reason to celebrate. Policy that improves #AirQuality & quite literally saves lives.

Science policy to improve air quality- especially particulate matter!
