 "Southern Ocean clear-sky brightening from sea spray aerosol increase drives departure from hemispheric albedo symmetry" 🌊☀️☯️

Check out the new version of my climate science textbook. Free, accessible and online. Let me know what you think. open.oregonstate.education/climatescien...

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/...

The deadline for graduate student applications for paleoCAMP 2026 (Paleoclimate Training in Climate Archives, Models, and Proxies) summer school is this Friday, January 9th! paleoCAMP is completely free for all students selected to attend paleoclimate.camp/apply

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...

Just putting this out there again - deadline 19th January: shorturl.at/wKh2W

Excited for this paper to be out! With the collaboration of met services from Central America, we evaluate in detail the biases in gridded products that arise from the underlying station data, and the effect this has on the apparent emergence of regional drying trends. Thanks to all the co-authors!

Exciting news! Student applications for paleoCAMP 2026 are open! Are you a graduate student working on any aspect of past climates or environments? Apply to be part of our 2-week summer school in the eastern Sierra Nevada! More details here: paleoclimate.camp/apply

New paper out by graduate student Andy Jones on California glaciers. www.science.org/doi/10.1126/...

🌊 In 2012, CGD’s Aixue Hu showed how closing the Bering Strait in models affects Atlantic currents. Today, Science revisits this idea, asking if a giant dam could help keep Europe warm. Why it matters: ocean gateways, tipping points & bold ideas all collide. 🔗 lnkd.in/gS_sHikw

With Rice University, a new project called the SCI-SWIM will help our Community Earth System Model trace where water comes from by focusing on stable water isotopes that give clues to the origins of water, from ice sheets to the ocean and everything in between. news.ucar.edu/133039/new-m...

Our paper is out today in @aguadvances.bsky.social 🥳! My coauthors and I use a simulation spanning the Last Interglacial (~130,000 - ~115,000 years ago) to show how changes in Earth's orbit impact atmospheric river behavior and the ensuing impacts on the Greenland ice sheet. 🧪🥼⚒️❄️ 🧵

A new paper out in AGU Advances led by Xiaoqing Liu in which we try to take the 'time' out of paleo and focus on the pattern of warming for wide range of global warming levels. agupubs.onlinelibrary.wiley.com/share/K8WWRP...

Thrilled to see two of my mentors Dr. Bette Otto-Bliesner (Suki Manabe Award) and Prof. Zhengyu Liu (Sverdrup Gold Medal) honored by @ametsoc.org for their pioneering work on Earth’s climate system through modeling and paleoclimate research. @ncar-ucar.bsky.social @ncar-cgd.bsky.social

Reporting on the NOAA Fellow furlough, from the @nytimes.com www.nytimes.com/2025/07/09/c...

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-...
