Today’s post focuses on weather in the Plains. High winds and fire danger there. Additionally, we take a look at the failure of Colorado River negotiations this weekend. This is a big deal, and we have a bevy of links to primary sources that explain this issue. Details below or at theeyewall.com.

The American Academy of Actuaries warns that dismantling NCAR would degrade the catastrophe models insurers depend on to price climate risk—driving up premiums and threatening coverage availability nationwide. "Uncertainty carries a positive cost." www.riskmarketnews.com/trumps-clima...

Last December, weather and climate scientists sat down with us to tell us why they loved the National Center for Atmospheric Research, and why it benefits us all. Last night, the NSF began dismantling it. Listen to what they have to say, and why it's urgent that we #SaveNCAR wclivestream.com/act

AGU has an easy-to-use toolkit set for public feedback to proposed government actions. Now is a great time to respond to NSF’s proposed shuttering of NCAR. agu.quorum.us/campaign/154...

We knew the NSF letter about NCAR would come. I think this is an occasion that will require great coordination and strategical thinking. UCAR should respond as a block, coordinating a response across universities (especially in the South, and large public universities that use NCAR data a lot)

I would strongly encourage those who value the scientific & societal legacies of NCAR to offer feedback by March 13. I would expect, under present circumstances, perspectives from industry partners will be especially critical, though everyone's voice is of course important.

#savencar So much American science passes through ncar. Some of my closest collaborators and smartest colleagues are at NCAR.

Thrilled to share our new paper in GRL investigating future changes to Indonesias Seas currents using a high resolution climate model (CESM-HR)! doi.org/10.1029/2025...

New study by Hu et al. reveals #IndonesianThroughflow’s nonlinear response to #CO2, with a rapid decline after crossing a #TippingPoint. The first point may be approaching, signaling a potential climate #Tipping element with implications for global #climate. www.nature.com/articles/s41...

Chris Piecuch shows how the rate of sea-level rise along the US coast has doubled since 1900, from 2 cm to 4 cm per decade. It has risen by 40 cm by now. Here he briefly explains this (and how the DOE claimed the opposite) at the AGU25 meeting last week. www.youtube.com/watch?v=fI0K...

From @AGU.org: Senators are working on legislation to save NCAR, but we need extra support for these 8 states. Your Senators in Alabama, Alaska, Florida, Louisiana, Mississippi, North Carolina, Texas, and Wyoming need to hear from you.

Last keynote for today by Sara Sanchez on "Data assimilation with coral d18O"

First keynote of today by Caroline Ummenhofer on "Indo-Pacific climate variability of the last millennium"

Next to presentations from 18 #SPP2299 projects, we have an impressive line-up of keynote speakers, including Andrea Grottoli, Alyssa Atwood, Caroline Ummenhofer, Sara Sanchez, Ben Henley, Christian Voolstra, as well as other excellent talks from our invited guests incl. Xuefei Chen and Mandy Freund

🌊🦠#FieldworkFriday Our fieldwork doesn't only happen at sea! C-CoMP researchers working with @maratimes.bsky.social collected Providence River water to test extraction methods for samples collected on C-CoMP cruises. In terms of filtering speed, 5 L of Sargasso sw = 50 mL of Providence River water!

Earth scientists know a lot more about getting out of an ice age than going into one. We report an episode of AMOC slowdown at 115 thousand years ago that's likely astronomically forced (via sea-ice) and coincides with a delayed drawdown of atmospheric CO2 @natcomms.nature.com rdcu.be/eALD1

📣#MTTM 🔬Emily Hu (@yunqianhu.bsky.social‬) is a C-CoMP B2P Fellow working with @maratimes.bsky.social & @akrinos.bsky.social at Brown. She uses microbial sequence data and computational tools to uncover how biotic🦠& abiotic drivers shape microbial community assembly in the North Atlantic Ocean 🌊.

Now out in Nature Geoscience! Evidence of subsurface Atlantic warming during past AMOC slowdown periods. It's an amazing study led by Wanyi Lu and I'm honored to have played a small role in generating some of the data! www.nature.com/articles/s41....

The National Science Foundation plans to abruptly end operation of the RV Nathaniel B. Palmer, the sole U.S. research ship capable of braving the farthest reaches of Antarctica and the Southern Ocean. scim.ag/4mB8LOX

We are pleased to have @cavemangriff.bsky.social and Sam Bova as invited speakers for our 4th #PaleoSEA session at #AGU25. Last week to submit abstract: tinyurl.com/paleoSEA2025 AGU Student Travel Grant: www.agu.org/honors/fmstg

Interested in how data, models, and theory can help us advance #paleoclimate research? Submit an abstract to #AGU session! Deadline to submit abstracts is July 30th 🌍⛰️📊💻 agu.confex.com/agu/agu25/pr... @agu.org

The Secretary of Commerce's new policy requiring his personal review of all NOAA contracts over $100,000 is directly harming American science. 🧪 How do I know? Because this morning, twelve of America's rising leaders in climate science (including myself) were furloughed.

As of today, all current NOAA Climate and Global Change postdoctoral fellows have been furloughed due to the Dept of Commerce not releasing the funding for the program. In addition no new Fellows were awarded this year. cpaess.ucar.edu/cgc

Calling all (paleo)climate thinkers, data wranglers, and storytellers of the Earth system! Join us for our 4th #PaleoSEA PP030 – Southeast Asia and the Indo-Pacific: Past, Present, and Future Climate and Environment at #AGU Fall Meeting 2025 in New Orleans, Louisiana. (1/2) @syiwang.bsky.social

Absolutely thrilled (and shocked) that our NSF proposal at P4CLIMATE was just recommended for funding! A ray of good news in the midst of everything going on 🎉🥳🙏

HAPPY 75th, NSF! We’re celebrating this milestone by highlighting some of NSF’s most transformative accomplishments—innovations that have shaped our world and continue to drive progress in health, technology, the environment, and beyond. Read on 🧵(1/11):

A victory for the federal scientific workforce! We could not stand by while this irreparable harm continues at NSF, NOAA and all our scientific agencies. TODAY the judge granted our request to temporarily HALT the mass firings at federal agencies under Trump’s Executive Order.

Exclusive: National Science Foundation staff were told today that the agency’s 37 divisions—across all eight directorates—are being abolished and the number of programs within those divisions will be drastically reduced.

Thrilled to share that @ncar-ucar.bsky.social wrote a short piece summarizing our recent paper on the drivers of Southeast Asian rainfall extremes! www.cisl.ucar.edu/news/cisl-po...

Foraminifera are one of the ocean’s most abundant, but overlooked inhabitants. It’s also one of the tiniest creatures I’ve ever shot for the Aliens Collection. The shell size is ~1mm, and the spicules reach ~5mm . . . #foraminifera #foram #microscopy #blackwater #gug #gugunderwater #chrisgug

This paper is incredible: one year of SWOT data gives us a much better picture of global ocean floor topography than all other data ever collected. And this will only keep getting better with more SWOT data. This one result may justify the cost of launching SWOT. www.science.org/doi/10.1126/...

Ozone hope? The 2024 ozone hole closer to the historical average in size and duration than the previous years. Does this signal progress towards recovery? Read the article atmosphere.copernicus.eu/ozone-hope-2... #CAMS

Had such a blast presenting, convening, and seeing so much awesome science this week at #AGU24! Special shout-out to the Airbnb espresso machine that kept me energized every morning ☕️

Excited to be presenting two posters at #AGU24 this week! If you're interested in rainfall, ocean circulation, paleoclimate, and tropical variability, come check them out Tuesday morning and Thursday afternoon!

So thankful for everyone that attended my PhD defense on Friday!
