New AMS Statement: Dismantling NSF’s National Center for Atmospheric Research would weaken U.S. leadership in weather, water, and climate science, putting public safety at risk. For more than 60 years, NSF NCAR has improved forecasts and early warnings that save lives. More: https://bit.ly/4q6eChn

What's NCAR? and 8 ways it has helped you www.forbes.com/sites/marsha...

#AGU25 folks, there is a rapid- response town hall TODAY on the #NCAR dismantling at 1 pm, La Nouvelle Orleans ballroom C (per an AGU media advisory)

AGU has a Congressional email and call script up on NCAR:

#AGU25: Please consider showing up to support Cobb Lab early career researchers from Brown. I especially want to flag undergrad posters Thursday pm and *high school* posters Thursday am. I'm incredibly proud of their hard work to get to this point!

It is hard to overstate how critical @ncar-ucar.bsky.social is to climate science in the US and around the world. It's the beating heart of our field. Generations of scientists have trained there, and almost everyone I know relies on deep collaborations with NCAR scientists. It's end is unthinkable.

I am safe, but still waiting to hear back from many students, staff, and colleagues. The darkest of days for Brown. My heart breaks.

In the world we live in today, that is 1.3C warmer due to our continued burning of fossil fuels, the extreme rainfall leading to disastrous flooding in many parts of Asia is up to 50 to 160% more intense - new @wwattribution.bsky.social study www.worldweatherattribution.org/increasing-h...

I have a new update to climate model-observation comparisons over at The Climate Brink, covering CMIP3, CMIP5, and CMIP6. Models perform well globally. The latest generation shows too much long-term warming but better reproduces recent trends: www.theclimatebrink....

Now that the Sept and Oct data are (belatedly) in, it looks like 2025 will be the second warmest year in the record (~80% probability). The last three years are in a class of their own.

IBES Director @kimcobb.bsky.social joined LA's AirTalk radio show to discuss Bill Gates's recent memo on climate change — in which he expresses concerns on how the climate crisis is being framed and addressed — and how should we talk about climate moving forward. laist.com/news/la-city...

I am hiring 4 postdoctoral researchers for up to 4 years each. Topics include ice sheet reconstruction, GIA, spatial stats, and satellite geodesy. Based in Tasmania. All details are here: careers.utas.edu.au/en/listing/ with titles below I am also recruiting multiple PhD students (see below) 1/n

📢Global Carbon Budget 2025📢 Fossil CO2 emissions continue to rise in 2025 while the terrestrial carbon sink recovers to pre-El Niño strength. The key findings are covered in two reports this year: * ESSDD (preprint): essd.copernicus.org/preprints/es... * Nature: www.nature.com/articles/s41... 1/

A sobering take on what a slew of new reports say about how the world will look under 2-3°C+ of warming. W/ @laurapaddison.bsky.social & insights from @drkatemarvel.bsky.social, @kimcobb.bsky.social, @weatherwest.bsky.social & others. www.cnn.com/2025/11/12/c... (For CNN subscribers.)

Job Opening **ASSISTANT PROFESSOR MARINE ECOLOGY**, Department of Biological Sciences, University of Rhode Island. jobs.uri.edu/postings/15960

Confused or curious about the Bill Gates climate memo? I've got you covered! TOMORROW at 1:30pm PT, I'm talking with 4 great scientists. Sign up for an important convo w/ @katharinehayhoe.com @kimcobb.bsky.social @hausfath.bsky.social @weatherwest.bsky.social: coveringclimatenow.org/event/the-bi...

I just donated to the Footprint Project, sending solar/battery/LED setups to Jamaica. Usually in the wake of a disaster you get noisy, polluting diesel generators that also need fuel. These microgrid setups will be useful and provide clean energy for years. www.footprintproject.org/rapid-disast...

We're hiring! We have an open search for an Assistant Professor in physics of the ocean and/or atmosphere in Columbia's Dept. of Earth and Environmental Sciences.

Last month the Department of the Interior stopped construction on a Rhode Island wind farm that was 80% complete. This week on Possibly we break down what the order means for Rhode Islanders: our clean energy, jobs, and utility bills. thepublicsradio.org/possibly-pod...

In the 1st half of 2025, @climate.noaa.gov 's staff were terminated, shutting down daily operations. Now, former members have joined w/ nonprofit partners to launch Climate.us, where climate info can be safeguarded from politics. Check out our website and join the effort today.

The Department of Energy hired five academics to raise doubts about climate change. 85+ climate experts (organized by @andrewdessler.com) reviewed their report. Our conclusion, detailed in 450 pages of analysis: it is biased, full of errors, and not fit to inform policy making.

@nature.com I love this article - but WHY are the only share options to X and Facebook when the whole point of the article is that science-based posts get more shares here? www.nature.com/articles/d41...

"At stake in the tumultuous century to come is how fast and how completely we will have to exchange the new for the beloved." Words to live by, thanks @brdemuth.bsky.social.

There’s so much happening right now, I thought I’d put together a running thread on the dismantling of #climate and research and knowledge infrastructure in the United States 🧵

I wrote this NASA page about wildfires and climate change, and I'm so excited it's finally live. It's a tireless effort to get big pages published at NASA - as it should be! How long will it remain up? Who knows. Check it out while you still can. 🧪 #climatesky science.nasa.gov/wildfires-an...

Yesterday I was asked to resign from the President’s Intelligence Advisory Board. I tendered my resignation with this note. Nobody will read it, most likely, but it’s the writing of it that mattered to me.

I'm excited to now share this with the world: Our new US DOT Climate Strategies That Work Playbook is live! It includes 27 evidence-backed local and state strategies for reducing GHG emissions from transportation. climate-strategies-that-work-usdot.hub.arcgis.com

With the (belated) September data now in, the updated prediction is that 2024 is almost certain to be a new annual surface temperature record, and possibly by more than 0.1ºC. 50% change of exceeding 1.5ºC above the late 19th C.

I'll be speaking to a largish audience of conservative-leaning students next week, on the topic of EVs and climate change. Pls drop ur must-have talking points (bonus for great graphs & stats) and good resources for digging into pros and cons. And yes, I'm the happy owner of two EVs!

Tenure-track job opening in Climate & Health at Brown University! It's broadly defined, and would join a team of newly-hired superstars already transforming this critical space. Target date 10/1. Info & app link here: apply.interfolio.com/152760

Yesterday was a big double-header with a keynote at Senator Whitehouse's annual RI climate event, and then over to a public talk at @wbur.org with the American Meterorological Society. Grateful for our strong community, and fueled up for the work - onwards!

The State of the Climate Report for 2022 is now available: doi.org/10.1175/2023.... I am happy to have played a small role in this year's issue again - see our section in 'The Arctic' chapter: ametsoc.net/sotc2022/SOT... Unsurprising, there were more climate records 🔥🧪⚒️
