Exploring Drip Water Dynamics for Groundwater Recharge The end of the year is approaching, and the papers and pre-prints are still coming from the groundwater and climate research team here and our collaborators. Here is a summary of our outputs the last three months of the year. All are…

There aren't a lot of resources for what people can do to prevent the destruction of NCAR, so I made this: #NCAR #climate #climatescience #weather #meteorology #activism #myresources

Join us for a critical conversation on the future of U.S. atmospheric science. UCAR President Antonio Busalacchi hosts this town hall on what’s at stake if NSF NCAR is dismantled. buff.ly/jR6tGwo

#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!

AGU25 attendees: Ever failed before? (probably, right?!). Then our panel discussion is for you! Come hear epic fail stories from your peers and maybe even share your own. Tuesday 16:15-17:45, Room 343 agu.confex.com/agu/agu25/me...

Here's the lineup of my group's presentations at #AGU25. Come meet with us!

🚨 New manuscript! 🚨 We use speleothem calcium isotopes and Mg/Ca to reconstruct rainfall amount. Turns out central Vietnam was 50 % drier during the LGM 🤯. Climate models agree but most underestimate rainfall change. www.sciencedirect.com/science/arti...

Who killed the hobbit? 💀🐘🦴⛰️🌧️☀️🪨⛏️ Our new paper out today in Communications Earth and Environment reveals the role of a major drought in the disappearance of the diminutive hominin Homo floresiensis. theconversation.com/the-hobbits-...

If you are at #AGU25 I shall be presenting a new reconstruction on Indian Summer Monsoon over the last millennium using speleothem records. agu.confex.com/agu/agu25/me...

I got my PhD in a geography department and the DDRIG program was crucial to funding the final push of measurements I needed for my dissertation. This sucks.

📣 We just released a new free resource at @climatecentral.org - a 72-slide deck introducing key facts about climate change, including its causes, impacts, and solutions. It also comes with speaker notes and links for local storytelling. ➡️ www.climatecentral.org/climate-matt... (English & Spanish)

As teams grow, new Ph.D. graduates are less likely to land tenure-track jobs and more likely to leave science—especially women and international researchers, according to research from last year. https://scim.ag/3JHinJs #ScienceMagArchives

Interested in #Maya history, #climate change, #stalagmites and #drought, and the #SYP autosampler? Read the latest in our detailed work on a sample from #Tzabnah cave! 😎 kudos to all our collaborators in #Mexico! @andy-baker.bsky.social @mwclimatesci.bsky.social www.science.org/doi/10.1126/...

Great to see our work in @eos.org ! A good read for the evening! 😇 kudos to all our friends & colleagues that contribute to this ongoing endeavour - there is so much to learn! 🤩 together - always! @thomasopel.bsky.social @juvmcburst.bsky.social @pucicu.de @scitobias.bsky.social @leverhulme.ac.uk

At some point, during grad school, @paleopatt.bsky.social, me, and other people joked on using Shaq as an unit system (distance, isotopic composition, etc). Glad to see the #Creepcast podcast having the same idea.

Speleothem science is cool 😎🦇💧 - come join the party at #AGU25! Submit your abstract to our session by July 30: agu.confex.com/agu/agu25/pr...

From ancient rainfall to roaming hominins — we’re connecting proxy records, climate models, and evolutionary stories. Join us at AGU 2025 to rethink how climate shaped human history. #Paleoclimate #ProxyVsModel #HumanEvolution #30thJuly

Excited to (finally) share my new paper on Pacific SST and western North America hydroclimate during the Holocene! TL;DR They are connected, CO2 and precession both affect hydroclimate. Thanks @xiaojingdu.bsky.social @meredithparish.bsky.social @baylorfk.bsky.social+others dx.doi.org/10.1029/2024...

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

Pleased to share a new paper from our socio-ecological research in Central America, led by Dr. Talia Anderson - Talia used a mixed methods approach to understand how perceptions & socio-economic factors mediate farmers' adaptations to climate variability and change link.springer.com/article/10.1...

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

I'd like to introduce a new page on my website: U.S. climate indicator visuals (zacklabe.com/united-state...). I only have a few basic variables so far, but I will be expanding this summer to add a range of metrics (e.g., ecological). I welcome suggestions! Hope this is useful, especially nowadays.

Argh. The P4CLIMATE program solicitation will be archived (the program website itself hasn't been updated) www.nsf.gov/geo/updates/...

NASA outreach event NOW by Toms diner

NSF grant terminations are disproportionately affecting underrepresented scientists. 58% of canceled grants have women PIs, despite making up only 34% of awards. 17% of canceled grants have Black PIs (versus 4% of the pool). Hispanic and disabled PIs are twice as likely to have NSF grants canceled.

I talked to NPR earlier this week - along with several other scientists - about how devastating the impacts of these NSF grant terminations have been (and it has only just begun...). #SaveNSF #StandUpForScience #NSF www.npr.org/2025/05/02/n...

Received some awful news about a major project (sites.ps.uci.edu/climatejusti... ) I have led for the past 2+ years. So many people have worked incredibly hard to realize our vision and this immediately cuts the funding for 15+ students and staff, as well as for our community partners

Big news: this EO will result in the end of the NASA GISS building above the Seinfeld diner (but the mission is ongoing) www.democratandchronicle.com/story/news/2...

Almost five years of cave climate monitoring in Australia and New Zealand It was back in 2020 and COVID lockdowns that ACKMA, the Australasian Cave and Karst Management Association, decided to lead a volunteer, citizen science project to measure the 'baseline cave climate'. That is, to collect…

Hi #speleothem folks, April is the month for third episode of ICCP speleothem lecture series. Dr. @annabelwolf.bsky.social will share her insight about Southeast Asian monsoon in past, present and future using water isotopes. E-see you on 21st April, 09:00 am KST

@clairerubbelke.bsky.social ‘s second PhD chapter is out in @natcomms.nature.com ! Her work shows a state shift in Southern African climate during the mid Pleistocene transition, with implications for understanding the future. (1/2)

NOAA just fired us, again 🤡 Retroactive to February 🤡

Dervla led a great paper we just had published: Optimizing Topographic Boundary Conditions for East Pacific Climate Simulation journals.ametsoc.org/view/journal...

I secretly (ok not so secretly) love these types of idealized experiments: agupubs.onlinelibrary.wiley.com/doi/full/10....

"I was eager to improve forecasts, especially for high-impact hazards like heat and heavy rainfall, using explainable AI. My work aimed to provide communities with actionable insights." Thanks to @moadlc.bsky.social for this awesome illustration! Check out @silencedscience.bsky.social for more.

After the excellent talk from @paleopatt.bsky.social, March is the time for second episode of ICCP speleothem lecture series. Dr. Elizabeth Olson from Union College will share her insight about the South American hydroclimatic change over the last 450 kyr. E-see you on 14th March, 09:00 am KST

AGU urges the Trump administration to immediately renew U.S. federal commitment to climate science. The U.S. must restore critical climate science leadership for a secure, prosperous future for the country and the world. Read AGU’s statement here: news.agu.org/press-releas...

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...

Last Tuesday, I was set to give a talk on 'climate change in the Northeast' at a retirement home but had to cancel due to hourly job threats. After nearly two weeks of overwhelming uncertainty, today it happened. I was fired from my dream of working at NOAA. I'm so sorry to everyone also affected.

S4 is on Bluesky now!

Trump and Elon have single-handedly ruined the scientific culture in the U.S. with devastating consequences.

Happy Valentine’s Day 😍
