New paper led by recent Auburn graduate Sarah Barney and w/ @richardsvachula.bsky.social , where we used charcoal to assess the type of vegetation burnt 🔥 in South China during the late Miocene when C4 grasses expanded (funded by @us-sciod.bsky.social; formerly USSSP) doi.org/10.1029/2025...

New Global Cave Monitoring Database: Insights into Drip Rates and Isotopes The PAGES-SISAL (Past Global Changes – Speleothem Isotope Synthesis and AnaLysis) team has created a new global database of cave monitoring data consisting of drip rates and drip water isotopes, and the modern carbonate…

We have a new paper out in Paleoceanography and Paleoclimatology showing that the latitudinal gradient in leaf wax hydrogen isotopes over western North America reflects the mean climatological position of the storm tracks. agupubs.onlinelibrary.wiley.com/doi/pdf/10.1...

New results from old ice....happy to answer any questions!

How does water get underground – and how much rainfall is needed to replenish it? Thanks to the amazing UNSW team for producing this story on our groundwater and climate research: past, present and future, featuring Marilu Melo Zurita, Martin Andersen, Ellen Corrick, Danyang Sun, Akhilesh Kumar,…

As a rare climate scientist working in Silicon Valley, I've been drinking from the AI firehose a lot more than my peers. I thought it would be helpful to lay out my experiences of both the promise and pitfalls of using AI to accelerate scientific research:

Really excited to see this paper out!! Led by @vtcoop.bsky.social we show that if you use cold and warm paleoclimates together, you can reduce uncertainty in Earth's climate sensitivity by quantifying the pattern effect and more precisely constrain future climate change www.pnas.org/doi/10.1073/...

New oldest dated rock art in the world, from Sulawesi (Indonesia). People have always made art! https://www.nature.com/articles/s41586-025-09968-y

Starting my academic reading this year with a fascinating study documenting the frequency of tropical cyclones in the South China Sea over the past ~650 years. We need more of this type of data to understand extreme weather patterns and their relationship with climate. www.pnas.org/doi/10.1073/...

Excited to share our new paper (w/ @aakashsane.bsky.social @baylorfk.bsky.social) where we used the CESM-LME and information theory to understand Pacific decadal variability! 🌊 link.springer.com/epdf/10.1007...

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...

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...

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.

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 🤡
