A huge thank you to everyone who attended last week's CESM Tutorial! It was great to connect with new and familiar faces. Through lectures, hands-on CESM training, discussions with scientists, and networking, participants built a strong foundation in Earth system modeling. 🌎

In April I had the opportunity to present my research on El Niño-Southern Oscillation at the Brown Graduate school Research Matter event. I’m very thankful for their support in creating a concise talk for a broad audience! Check it out at the link below! 🪸🌎 m.youtube.com/watch?v=e2XB...

I'm excited to share that I'll be joining the @csuatmossci.bsky.social as an Assistant Professor in Jan. 2027. Interested in research on the physics and dynamics of Earth's climate? Please reach out! If you don't know Fort Collins, here's The Diamond on Longs Peak at sunrise, as seen from the city.

paleoCAMP 2026 comes to a close, our 5th year of this 2 week intensive summer school for graduate students in paleoclimatology. A wonderful group of creative and energetic students, a beautiful early summer in the varied landscapes of the eastern Sierra, and a compassionate group of instructors.

The @financialtimes.com―my favorite news source―is covering moist heat stress& sports. It's a great read and supported by data analysis by my former phd student, Qin Qin Kong and me. authors: @attractamooney.bsky.social @nassosstylianou.bsky.social @janatausch.bsky.social www.ft.com/content/3b37...

Interested in paleoclimate science? Join us at the CESM Workshop (June 15–17), with the paleo session on June 17. Discover exciting new research, mostly presented by early-career scientists. Free online registration & multiple in-person attendance options available. www.cesm.ucar.edu/events/works...

The 31st Annual CESM Workshop is almost here! In-person registration closes June 5. Join us for plenaries by Duncan Watson-Parris & James Done, plus sessions on storytelling, ML, Earth system prediction & high-res CESM. Registration: www.eventsquid.com/mobileapp.cf...

#ExtremeWeather events are becoming more disruptive. A new @nationalacademies.org report and interactive site—with contributions from #NASmember Isabel Montañez—explore how paleoenvironmental records can reveal past extremes & strengthen future resilience: nap.nationalacademies.org/resource/292...

the final bit of my PhD work is now out in ERL! we look at how recent trends in tropical Pacific SSTs contributed to forest fire & climate trends in the Southwest US vs Eastern Australia (two super fire-prone regions with opposite-signed ENSO teleconnections) 🔥🌬️ iopscience.iop.org/article/10.1...

Introducing "TEXAS" — a PSM for #TEX86! Culture & mesocosm data constrain T response above 30°C. Ring Index brings culture/mesocosm GDGTs into agreement with coretops. Not linear, not exponential — the T–GDGT relationship follows a logistic S-curve. Preprint: tinyurl.com/2kfadt9p Stay tuned!

NSF NCAR CGD scientists joined a Texas A&M workshop on high & ultra-high resolution Earth system modeling. As models sharpen from ~100 km to ~3 km, they can better capture regional detail & extremes but bring big scientific and computational challenges. Proud of our CGD scientists!

A record-setting marine heat wave has formed off Southern California, and the next few weeks may determine whether it fades or deepens into summer.

Most of my career has been in area of climate science called "the pattern effect". Work over the last decade (including my own) has led to a simple paradigm for the mechanisms of the pattern effect. In this new preprint, we argue this paradigm is woefully insufficient arxiv.org/abs/2603.24488 1/

The forgotten role of wave dynamics in modulating the low cloud response to warm pool warming

The Pattern Effect describes the dependence of top-of-atmosphere radiation anomalies on changes in the pattern of sea surface temperatures. The emerging consensus in the field explains the impact of P...
