Wrapping up 2025 with AGU in New Orleans felt just right. Shared work on GPU native land surface modeling and an invited talk on trait based radiative transfer, plus the hallway conversations that remind me why I love science. Grateful for this community and looking ahead to 2026. #AGU2025

A great (pre-)christmas gift: our synthesis paper in Ecology Letters just got published! 😊 Thanks, @elsa-abs.bsky.social, @arjunchakrawal.bsky.social, @lucianachr.bsky.social, Pierre Quévreux, and @manzonilab.bsky.social for the great collaboration!! Open access article: doi.org/10.1111/ele.70278

Land ecosystems and the ocean are responsible for absorbing the other 50% of anthropogenic emissions. Land sink account for about 21% (8.7 GtCO2/yr, average over last decade). Ocean sink accounts for 29% (8.7 GtCO2/yr).

Excited to help convene The Living Land session at EGU 2026 together with colleagues from the MC³ Center. If you work on how land processes feedback on climate, from vegetation change and fire to permafrost, water and energy fluxes, we’d love to see your abstract! See you in Vienna.

From NASA to the National Institutes of Health, federal agencies conduct research that universities cannot. Agency scientists speak with Nature about the irreplaceable facilities, institutional knowledge, and training opportunities that the country is losing. 🧪

Just published, a land-mark paper by Annemarie Eckes-Shephard et al.! It assesses the performance of a new generation of Demography-enabled Dynamic Global Vegetation (D-DGVMs), that attempt to simulate the changing size and age structure of trees in forests.

Grateful to see our paper featured in an Eos Research Spotlight, “How Plant–Fungi Friendships Are Changing.” Cool title!

🌎 Our recent work on CO₂ vs climate impacts on the global carbon sink, led by Eren Bilir, was selected for an Editor’s Highlight in Eos! A huge thank you to Dr. Sharon Billings and the editorial team at AGU Advances. eos.org/editor-highl...

New CliMA post about our study out in Nature Comms! We show that replacing fixed plant types with real leaf traits in climate models changes everything — from surface albedo to rainfall. Darker Amazon, brighter Siberia. Climate shifts follow. #climate #remotesensing

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.

Carbon-I 🌎🛰️ is one of four candidate missions selected by NASA for one-year Phase A concept studies. Join us on 7/22 for a talk from PI Prof. Christian Frankenberg as he outlines the mission concepts and paths forward. Register here: bit.ly/Carbon-I Read more: kiss.caltech.edu/lectures/202...

NASA’s PACE mission just released its first year of data—capturing seasonal shifts in chlorophyll & other traits. In our new paper, we show how trait data can shift climate model predictions of energy & carbon fluxes. doi.org/10.1038/s414... PACE shows what’s happening. We ask: what does it mean?

🌿 Feeling proud and grateful! Our recent @natcomms.nature.com paper was just featured in Scienmag! 💡 It’s rewarding to see this kind of attention highlighting the importance of linking traits to how we model the Earth system. 👉 scienmag.com/how-leaf-tra...

New study by Wang, Braghiere (@renatobrgh.bsky.social‬‬) et al. shows how the use of #plant traits can improve modeling of global #carbon, #water, and #energy fluxes, and consequently lead to improved #climate projections. www.nature.com/articles/s41...

🌱 New in Nature Communications! We show that replacing plant functional types with trait-based leaf optics into CESM & CliMA improves surface reflectance, shifts albedo >5 W/m², and alters regional climate projections. 📖 Read: www.nature.com/articles/s41... #Climate #LandModeling #LeafTraits

Non-living carbon pools are key in carbon storage! ESA Climate Change Initiative's RECCAP study shows soil, sediments, and wetlands as major sinks, challenging the belief in forests' dominance. These findings offer crucial insights for future climate modelling. 🌿💧 climate.esa.int/en/news-even...

Mask up, Pasadena! #Eatonfire #climatecrisis

While the #Eatonfire is 45% contained and air quality is good at #Caltech (PM2.5 = 8.7 ug.m-3), asbestos fibers might still be floating in the air. It’s recommended to wear N95 masks outdoors and run air purifiers indoors. Mask up, LA!

more and more every single day I understand this exact feeling. Don't Look Up was never satire for us climate scientists. It felt more like a documentary.

#JPL has so far been safe as well thanks to round the clock work of our first responders. But over 150 JPLers have lost homes that we know of so far. We are raising funds to support them through Caltech! Please consider supporting: caltech.imodules.com/controls/ema... Thank you!

Grateful for the concern and support! My loved ones and I are safe, but my thoughts are with those affected. As recovery efforts continue, I’ll share updates on how we can help rebuild and support impacted communities in Los Angeles. #JPL #Caltech #CommunitySupport #Resilience
