We're hiring! I'm recruiting a Postdoctoral Research Associate in climate & paleoclimate modeling of the tropical Americas. Come obsess over the tropical rain belt with me! :) Please share w/folks who may be interested. Ad here: wustl.wd1.myworkdayjobs.com/en-US/Extern...

Our GDGT Cookbook paper is out now in Biogeosciences! @egubg.bsky.social Thx Peter Bijl and @kasiasliwinska.bsky.social in spearheading on this. Hope it will help people who study #TEX86 for a bit! Proudly present Figs 1 and 4 that I made for the paper 😎 Great pleasure working with y'all!

This newly published study is in favor of a (further) consideration of isoGDGT-0 and crenarchaeol in addition to isoGDGT-1 to isoGDGT-3 and crenarchaeol isomer for paleo-reconstructions. Siqi Zhao et al. (2025) @commsearth.nature.com doi.org/10.1038/s432... 🧪 ⚒️ 🌊 👩‍🔬 #PaleoSky #GDGTs #TeamArchaea

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

I hope a journalist on the climate beat will report on this - this may be only one piece of the general awfulness that is happening to federal science, but the NOAA Climate and Global Change Fellowship has trained many of the current leaders in weather and climate: cpaess.ucar.edu/cgc/current-...

This fellowship was a huge part of the reason I am continuing to do climate science, and it has supported so many incredible people. These effects on early-career researchers, who do some of the most impactful work, is going to have long-lasting implications for science and scientists.

The Trump assault on science is an assault on scientists - an assault on their careers and dreams, their lives and their families. It is a waste of training and talent. It impoverishes all of us.

The Dept of Commerce has forced the NOAA C&GC program (which supported my postdoc) to furlough their postdocs. Postdocs are at a precarious career stage - folks move across the country/world, often w/o much of a local support network

I was also a Fellow. This program brought me from my home country of Australia, providing me resources+networks that paved my career path to becoming a full professor in a US institution. Having now worked with many undergrad/grad/postdocs, I have witnessed CGC benefits to society at large.

One of the things that makes this Fellowship special is that unlike NSF fellowships it is open to non-citizens, with the aim of retaining climate science talent in the US. The furlough creates significant problems for non-US postdocs in how it complicates visa status 😳

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 am one of the people who have been furloughed. And just to deal and prepare our backup plans for this unfortunate event is mentally taxing. I hope that we are getting out of this series of unfortunate events soon.

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

Another cool paper coming out of @amglab.bsky.social. Led by Tanja Wald, here we present basin-wide profiles of Mediterranean nitrate N/O isotopes, and show that this distribution can be explained by a combination of nitrogen fixation and anthropogenic nitrogen deposition: dx.doi.org/10.1029/2023...

With each passing day, this administration further degrades U.S. scientific capabilities. If we stop collecting climate data, it will not alter reality. It will make us less prepared to address the damage & pain human-induced, climate change generates. This does not make us great. 🧪🔌💡🌊 ☀️💨🔋

There have definitely been some significant changes to the NOAA Climate website "https://www.noaa.gov/climate" in the last 24 hours... For example, removing links and references on the page to 'Climate Ready Nation' initiatives. Stripes are gone too.

A bit late to the #ShowYourStripes Day... but a trend of my hometown temperature change does not look "cool" at all 😅 showyourstripes.info/c/asia/thail...

Thank you for your warm welcome, Nina! @ninadavtian.bsky.social. Bluesky definitely makes me miss the old good days in #Twitter! Glad to join #PaleoSky!

Archaea xkcd.com/3095/

We’re wasting the remaining carbon budget on war and AI.

Trump administration cuts to NSF will result in more than 200,000 FEWER people per year involved in basic science, training, and education - what should have been the next generation of US scientists. This isn't even eating your seed corn, it is setting your seed corn on fire and salting the earth.

Wow... I feel missing out for not migrating from the e[ #X ]tinct app to #BlueSky here sooner! So, please allow me to repost my very first PhD paper in published in @pnas.org here.

Can tropical corals find refuge at higher latitudes under future warming? In our new paper in Science Advances, we argue that coral range expansion will be *far too slow* for most coral species to outpace climate change. 🪸🌊 www.science.org/doi/10.1126/... A short 🧵 (1/16)

Now published in @agu.org Geophysical Research Letters! What happens to marine archaea when they’re hungry? And what does that mean for the TEX₈₆ paleothermometer? Full paper here: doi.org/10.1029/2025... Thanks to my coauthors and mentors for their support — and stay tuned, more is coming!
