NCAR has been the magic sauce that has made weather/climate studies and advances in US and the world over great. madison.com/news/local/e... www.jsonline.com/story/news/e...

NOAA has started terminating grants to UCAR under the UCAR/NOAA Climate Adaptation and Mitigation Program (CAMP).

Some reflections after returning back from a conference at which I and 20,000 colleagues learned that the Trump administration intends to dismantle #NCAR. This outrage should not happen. deepconvection.substack.com/p/save-ncar

““Everybody on that floor knows what an excellent job [it] does,” he said, pointing to the Senate floor.” thehill.com/homenews/sen...

Grateful to Senators Bennet and Hickenlooper for taking this critical action. We’ll continue to support their efforts every step of the way!

The Trump Administration's plan to dismantle the @ncar-ucar.bsky.social is senseless & dangerous. It would weaken weather forecasting, climate research, & the science that keeps people safe. We urge that this plan be abandoned. Call Congress to #SaveNCAR today. buff.ly/7ka1BQA

🚨 Calling all geoscientists 🚨 If you or anyone you know is attending #AGU25, please join us and spread the word to #SaveNCAR. More info at: wclivestream.com/ncar_at_agu/

Here's our reporting on the proposed dismantling of the jewel of US atmospheric science, @ncar-ucar.bsky.social. The plan is to break NCAR apart and disburse some parts to other locations (like the research aircraft fleet) and eliminate others. www.nature.com/articles/d41... 🧪 #AGU25 #climate

12:15 Thursday at AGU for those attending

Threatening to dismantle NCAR, our premier weather and climate research institute (apparently) because Colorado refuses to pardon someone accused of tampering with voting machines is a sad example of our current kakistocracy in action… www.nytimes.com/2025...

Gonna keep posting about this. Dismantling NCAR is stupid and dangerous; doing it as payback to the governor of Colorado is idiotic.

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

NCAR’s Mesa Lab is literally a science castle dedicated to understanding our planet in an open and collaborative way, and leading the world in that effort. We cannot let this happen.

Library of Alexandria level destruction

Friends at NCAR, we're with you. @ncar-ucar.bsky.social is a trailblazer in community modelling driven not by idealogy, but by open science. We share all our code, thoughts, ideas. These can't be shut down. We'll fight and find every mechanism to support the ongoing CESM community.

The beautiful idea of NCAR, to improve understanding of our planet through a cooperative, shared and open intellectual team effort, is literally what has got me out of bed every morning for nearly two decades. This cannot, CANNOT be allowed to happen. eu.usatoday.com/story/news/p...

Earthquake! (yesterday, not near me right now) @gfun.earth earthquake.usgs.gov/earthquakes/...

I'm not attending the AGU meeting this year but you can check out these collaborations with my group!

The NorESM community will (also!) be running a tutorial in January 14-16th, in Bergen, Oslo and online (for those who prefer their ESM tutorials in an Euro-timezone!). It is focused on NorESM2.3 but the workflow will be similar for the (in development) NorESM3. docs.google.com/forms/d/e/1F...

Happily, there will be a CESM tutorial again this year @ncar-ucar.bsky.social Also, much like learning a Scandinavian language, once you can run CESM, you can probably also run NorESM, CMCC and E3SM, so it's like a 4-in-1 deal... :) www.cesm.ucar.edu/events/tutor...

Good questions to be asking! I remember @profdesai.bsky.social had some really good advice for me on how to write these letters but it is lost to the ancient history of twitter.

Oh interesting, whose fault is that?

Our department at UBC is hiring for a professor of forest ecophysiology, including "tree ecophysiology; plant abiotic or biotic stress physiology; forest mortality and climate change responses; forest carbon balance; tree water relations; or nutrient use." Learn more at: tinyurl.com/5da56f5c

New lab paper: How does photosynthesis respond to assumptions about stomatal functioning? We find that including atmospheric feedbacks reverses the direction of photosyn. response => stomatal cond. changes temp. & water stress. Led by Amy Liu, w/ many collaborators! doi.org/10.1029/2025...

Making a climate model that works well is really, really hard. So hard, in fact, that the people who do make it happen rarely have the time or energy to talk about how hard it is on the internet. So most other people have very little understanding about how hard it is... But boy is it hard #NorESM3

New #FATESmodel job focused on fire modeling at UCIrvine :) recruit.ap.uci.edu/JPF09965

On Monday 10th @14:00 BST |15:00 CET |07:00 MT, the International Land Model Forum and ISI-MIP are hosting a joint webinar. Topics will include: The design of ISIMIP experiments, Harmonization of forcing and land-use data, Shared challenges e.g. generating sub-daily forcings for offline forcing.

Last week, my Foundations of Human-Computer Interaction class covered an older paper about “social translucence” where they explain how the design of online systems shapes the norms & behaviors w/in those systems. But the framework they create can be applied more broadly, eg to our political moment.

This totally happened to the kids Halloween haul last year 😭

Climate change DEFINITELY affects hurricane: STRENGTH: Warmer water is hurricane food RAINFALL: Warm air holds more water vapor SURGE: Warmer water expands, warmer ice melts, sea levels rise PREDICTION: hotter seas mean faster intensification

I'd like to go to the #EGU meeting this coming year. Any tips for a many-time AGU attendee going to their first EGU?

I've been involved in this CH4 vs CO2 thing for years, and indeed GWP* is a concise embodiment of the concept I proposed in my Annual Reviews article on short lived climate pollution. I cannot understand why something like GWP*, which demonstrably

I’m wondering if @ternbicycles.com knows that there are a whole bunch of climate scientists who ride GSDs!

I'm happy to share a paper in Science Advances that makes the case for a weak land carbon sink, drawing upon JPL and Chloris biomass time series. To close the budget with a net land sink of 0.8 Pg C/y from 2000-2019, we propose increases in the ocean sink and decreases in fossil fuel emissions.

Maybe the land carbon sink is weaker than we thought. Big implications: "A lower-than-expected land carbon sink would also imply that the land biosphere may be closer to transitioning from a net carbon sink to a net source than current models predict" Randerson et al. www.science.org/doi/10.1126/...

If you want to get your simple climate model picked up by IPCC AR7, see below 👇 We have 11 on our radar from the previous round of RCMIP (egusphere.copernicus.org/preprints/20...), plus a few others we found since. Anybody we don't know about please ping me or Alex

Our finalised paper on flat10MIP is finally up in GMD! This is the experimental protocol which allows for a simple, emissions-driven evaluation of TCRE, ZEC and climate reversibility in CMIP7. Thanks so much to all who ran these simulations as a proof of concept! gmd.copernicus.org/articles/18/...

flat10-MIP has landed! gmd.copernicus.org/articles/18/...

very nice article by @afreedma.bsky.social at @cnn.com about our comment on the DOE report www.cnn.com/2025/09/02/c...

More coverage of the scathing review by more than 80 scientists of the report from the DOE's climate working group. It's biased, cherry picked, and written with a scientifically unsupported agenda. www.theguardian.com/us-news/2025...

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.

Having spent much actual and emotional time and energy responding to this report, I whole-heartedly agree. Greenhouse gas emissions are bad for our planet, it's not a matter for debate.
