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

Still catching my breath after a wonderful #AAAR2025 meeting last week in Buffalo, NY. It is always to nice to reconnect with such a kind and welcoming community. I was proud to have 3 presentations from my group, including PhD students Sofie Schwink and Rileigh Robertson.

Absolutely star studded awards ceremony this morning - Welcome new AAAR Fellows Jesse Kroll @jessekroll.bsky.social and Pat Keady! AAAR Fellows make up 0.2% of the AAAR membership. They are recognized for their significant contributions to aerosol research and service to AAAR #AAAR2025

So proud to share this new paper from my research group in collaboration with NIST scientists during the CASA Field Study! We look at particle transport in a house and compare 3 models: a box model, an empirical model, and CONTAM. www.sciencedirect.com/science/arti...

I forgot to share this here... It was a wild moment to be recognized in front of 50,000 #CUBuffs fans back in August. www.linkedin.com/feed/update/...

Today, I received a termination for my National Science Foundation CAREER Grant, which employed a post-doc and many undergraduate research assistants.

🧪 Reports from inside NSF - staff were informed another huge set of grants were terminated today, that NSF will have at least a 50% total RIF, & no Acting Director has been appointed. So, who is leading NSF? #SciSky @science.org @scinews.bsky.social @aaas.org @aeraedresearch.bsky.social

Preliminary number of NSF grants to be terminated today is ~600, per sources. Including last week's cluster, this would put the total around 1,000.

I just got the email, my funding request to #NSF was approved a while back, but NSF will not provide the funds. I feel awful for my students. I feel awful for my program manager. I feel awful for #science & #America

---ATTENTION---ATTENTION--- I have now heard from several reliable sources outside and inside NSF that the fears about research.gov are not well-founded. I apologize for contributing to excessive concern. But, better safe than sorry these days...

URGENT ACTION FOR NSF GRANTEES. For current & recent (since 2020) awards, archive your award history this afternoon/tonight. Screenshot/download/print your work in research.gov & alert your partners. We have credible threats to integrity of awards tracking systems (via @jeremymberg.bsky.social)

This administration plans to eliminate NOAA Research, which costs every American citizen less than a cup of coffee a year. Do you like knowing the weather forecast? Being warned of hurricanes, wildfires, tsunamis? It will all go away if the public does not act. www.ametsoc.org/ams/about-am...

😍 look 👀 #Boulder voters! If they can close 54 streets, we can close two more blocks of Pearl Street. Sign the petition to get this on the November ballot. www.pearlforyou.org

A reminder that if the government can send migrants to a prison camp without any due process, it can send U.S. citizens there, too. I know because this happened to me and my family in 1942.

"I know how lethal Donald Trump’s assault on America’s outbreak preparedness could be. We are sure to regret it," warns @craigspencer.bsky.social @theatlantic.com www.theatlantic.com/ideas/archiv...

March is Women's History Month. Tough to be a woman right now and a scientist on top of it. But we carry on and we support one another!

The American Meteorological Society warned the firings will “cause irreparable harm and have far-reaching consequences for public safety, economic well-being, and the United States’s global leadership.” www.science.org/content/arti...

Here's the monthly future-fantasy Keeling curve update: Based on the most recent NOAA data from March, 2025, CO2 is now expected to peak in the year 2129 at 554.01 ppm. This is the first time the projected peak has been above 550 ppm and the first time it's been more than 100 years in the future.

Just a few things the US EPA has done to save millions of lives in the US alone. EPA exists to protect YOU and the environment.

At least 880 NOAA employees were fired today with hundreds more expected as soon as Friday. Right as there's: 🔥 a red flag warning for most of Nebraska and Iowa 🌪️ severe weather season picking up next week in the South 🔥🔥 "significant" wildfire potential for the Southwest and Southeast next month

Gregg is a former Marine and Forest Service ranger. He's saved the lives of hikers dangling off a cliff or going through cardiac arrest, and he's bravely fought forest fires to save small rural towns. 100% of his salary is paid by WA state. Elon fired him. Share his story.

The rise of gen AI, backed at every level by the far-right, suggests the arrival of an _anti-information_ age. AI offers a self-reinforcing bullshit loop that, much like a Russian disinfo operation, serves to muddy the information space and create doubt about the very nature of reality.

The idea of NSF giving money to private companies is all kind of levels of dumb, but fundamentally it's wrong strategically because it misses the fact that NSF money, primarily, funds students and postdocs training and education as scientists and researchers. Private companies won't do that.

I am not making this up: Republicans have introduced legislation… to increase your bank fees.

'Catastrophic': 'Reckless actions' by the Trump Administration throw Yosemite into freefall as high season approaches. www.alternet.org/yosemite-gov...

Yosemite reservations for peak June-July season are suspended (for the first time ever?!). We’re trying to stay hopeful, but feeling awful for National Park Service employees right now.

Our parks are in chaos. We’ve seen firsthand how Trump’s hiring freeze, the rescinding of hundreds of job offers, and the layoff of 5% of NPS staff have left us overwhelmed and short-handed.

Here is what the censoring of data.cdc.gov looks like over time

We are alarmed by the Administration’s actions to freeze science funding and eliminate DEI efforts and climate change initiatives, which go against AGU’s mission and harms our members. We must unite to address these changes, beginning by hearing from you. Read more: https://buff.ly/4hm8r4e

The entire archive of all CDC datasets uploaded before January 28th, 2025 has been backed up on Internet Archive. Incredible work everyone. Science will never be silenced!

“Many of those interviewed broke down in tears as they described the rapid destruction of decades of work. The programs that have frozen or folded over the past six days supported frontline care for infectious disease, providing treatments and preventive measures that help avert millions of deaths”

NEW: Two top security officials at USAID were put on admin leave Saturday night after refusing to allow officials from Musk’s DOGE to access systems at the agency, even after DOGE personnel threatened to call law enforcement, multiple sources familiar told CNN www.cnn.com/2025/02/02/p...

Trying to understand what is being construed as “DEI research”, and this report is illuminating. Keywords that put you in that group include “climate change” and “environmental governance”. Also “gender”, “socioeconomic”, and “trauma”. www.commerce.senate.gov/2024/10/new-...

The carefully managed water systems in California's Central Valley saw a sudden deluge after the Army Corps of Engineers unexpectedly released reservoir water. “In 25 years, I’ve never seen anything like this. I was given no explanation at all.”

Finally, it is Friday.

If I were the richest person on planet Earth, I’d like to think I’d try to shore up the research enterprise rather than using all my influence to make young researchers’ lives more precarious

It’s official: all funding requests made on Tuesday by postdocs for their salaries have been unilaterally rejected by NSF.

Every day, I try to walk home before the sun sets behind the Flatirons. It takes some guesswork but it's exciting that right now it's a bit later each day. Today, I discovered a website that can well me exactly when that is! shademap.app

Will our current CDC be in a position to report if person-to-person #birdflu #avianflu starts happening? Following @corsiaq.bsky.social's lead, here's a screenshot of my post on Twitter from January 2020:
