For the first time, independent monitoring data from #ICOSCities confirms that GHG emissions in Paris have decreased by 25% in the last decade, aligning almost perfectly with the 26% CO₂ reduction reported by Airparif (2015–2022). 👉 Read more in FLUXES: www.icos-cp.eu/fluxes/4/det...

[1/2] 📢 GLAMOS @scnat.ch press release out today: Swiss glaciers lost another 3% of their volume in 2025, the 4th-largest decline ever measured. In just 10 years, they’ve lost a quarter of their ice mass. Over 1k small glaciers have already vanished. 🔗 to press release: scnat.ch/en/uuid/i/9d...

Climate change is reshaping forest growth 🌳🌡️💧 Water and temperature control growth timing. Warmer winters make some species start growing earlier. Hot, dry summers may shorten growing seasons. New paper out @globalchangebio.bsky.social led by a former PhD student @csic.es shorturl.at/5Gn8a

Maybe the land carbon sink is weaker than we thought. Big implications: "A lower-than-expected land carbon sink would also imply that the land biosphere may be closer to transitioning from a net carbon sink to a net source than current models predict" Randerson et al. www.science.org/doi/10.1126/...

✨ Paper spotlight ✨ (🧵 1/5) Distal to proximal: a continuum of drivers shaping tree growth and carbon partitioning doi.org/10.1111/nph....

🌳 New Tansley Insight! What really limits tree growth—carbon source or sink? 🤔 I argue it’s not either/or but a distal → proximal continuum: from photosynthesis to transport and cell division, drivers act together to shape C allocation & growth 🌱🌍 🔗 nph.onlinelibrary.wiley.com/doi/10.1111/nph.70516

Our new article is out in @geoderma.bsky.social! Drylands, which cover 40% of Earth’s land, store ~30% of global soil organic carbon. But how do different carbon fractions support ecosystem services under rising aridity? 🏜️ 📖 doi.org/10.1016/j.ge...

Ready for a fresh start at @csic.es, in beautiful Granada, to study the impact of climate change on tree growth and the carbon cycle. Keep posted for PhD and postdoc position announcements!

Este manifiesto no es una súplica. Es un grito. Es un puño sobre la mesa de la indiferencia. Es un llamamiento urgente a la conciencia del mundo. ¿Qué futuro estamos construyendo, si ante un genocidio televisado, todavía no hemos hecho todo lo posible para conseguir paralizarlo?

$500 million is… less than 1.25% of the NIH’s 2024 budget. When I say there is no capacity to absorb the shock, I mean it.

Generalized Stomatal Optimization of Evolutionary Fitness Proxies for Predicting Plant Gas Exchange Under Drought, Heatwaves, and Elevated CO2 📄 https://buff.ly/3CAFh27 #photosynthesis

Successful sampling trip at @barbeau-fr-fon.bsky.social with colleagues from ESE lab as a part of a @snsf-ch.bsky.social project. Incredibly grateful to the tree climbers who took samples up to 20 m high! This will help understand how and why tree growth varies along the trees' vertical axis.

Although NOAA's page on atmospheric CO2 levels has vanished, you can still get this vital information from Ralph Keeling's team at the Scripps Institution of Oceanography, UC San Diego keelingcurve.ucsd.edu Please follow bsky.app/profile/keel... for updates and share Don't let science be hidden

We develop a new, generalized optimality theory of stomatal conductance by incorporating the non-steady-state physics of water, carbon, and heat within a plant into an effectively instantaneous solution. Congrats Aaron Potkay!! doi.org/10.1111/gcb....

BREAKING NEWS: CDC orders mass retraction and revision of submitted research across all science and medicine journals. Banned terms must be scrubbed. Goes beyond MMWR +other CDC pubs. Applies to research already submitted to top medical journals. Take a look. open.substack.com/pub/insideme...

📢 Calling all tree-ring researchers! 🌳💍 The Association for Tree-Ring Research (ATR) annually awards prizes for the best Ph.D. & Master’s theses in tree-ring science! 🗓️ Deadline: Feb 15, 2025 📄 Details: tinyurl.com/ATRaward Nominate your students! ✨

For profit publishing is vamperizing academic research. Gold open access is just displacing the problem.

Previous research showed tree growth to be temporally decoupled from GPP, but what about biomass? Here we find that the fraction of GPP allocated each year to woody biomass widely varies across sites and years, notably as a function of climate. Shout out to Steve Kannenberg for leading this work!
