🌍🌡️I'm excited to share my latest editorial for @commsearth.nature.com on how to avoid Earth System tipping points and trigger more positive change. Thanks to @exeter.ac.uk for organising two vibrant events on the topic Read more 👉 www.nature.com/articles/s43...

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

Fibre-optic cables (also used for internet) can be used as a novel means of continuous measurements of #forest #microclimate in space and over time, at 25-cm spatial and 1-minute temporal resolution New paper @methodsinecoevol.bsky.social: doi.org/10.1111/2041...

Beautiful day for an early Fall walk @harvardforest.bsky.social

Was just sent this photo: the oldest-documented Loblolly Pine (Pinus taeda) is still kicking. First scientifically aged in 1992, this lovely is now rapping up its 260 year (260 years at being 1/2 m or so tall; phot by J. Scheff)

Substantial Deep‐Soil Carbon Losses Outweigh Topsoil Gains in European Beech Forests Since the 1980s 🔗 buff.ly/7cUShZ5

🎓 Please join us for a PhD in Remote Sensing of Vegetation Structure at Aarhus University. It's a great place to live and work, and an inspiring university to do research 😊 phd.nat.au.dk/for-applican...

While southern Europe is used to summer fires, this year’s unusually dry/warm conditions from consecutive heatwaves are the main cause of the severe season. Bellow 2025 FWI anomalies, a key indicator of fire-prone climate conditions and fire hotspots, largely overlapping with the anomalies.

Protected areas safeguard old-growth forests against human land use, but not against the impacts of anthropogenic climate change. Here we show that a climate-mediated increase in disturbances could cause a decline in old-growth forests in a national park in C Europe. doi.org/10.1088/1748...

Fine work that both extends our knowledge of the past and has implications for today. Ndee (Western Apache) land management did a remarkable job controlling forest fires, even in drought-heavy eras like ours. It defies belief to think today's fire-torn SW has nothing to learn from those guys.

A very comprehensive analysis of lagged precipitation effects in terrestrial ecosystems. Tree rings, flux, grassland ANPP, satellite remote sensing, and DGVMs. Climate memory is an important driver of global plant productivity.

Ancient tree rings reveal how climate influenced Chinese dynastic history. Research on Qilian Juniper trees on the Tibetan Plateau shows arid periods coincided with dynastic upheavals. The study highlights links btw #climate stress & societal unrest over millennia. buff.ly/P4pDRJv #Science #Trees

Canada’s forests are losing their ability to bounce back from drought—and we now have the data to show it - Using tree-ring data from 40,000+ trees across 4558 plots and 23 species, we explored how trees responded to drought over the past century In GCB onlinelibrary.wiley.com/doi/10.1111/...

As others have noted, it is a big mistake to conflate U.S. higher education with Harvard, Oberlin, UC Berkeley, University of North Carolina, etc. There are great faculty and students at many non-elite campuses, where admission is not very competitive and where students can get a great education.

I have a fully funded PhD position open for start in Jan or May 2026. Field work in peatlands of the Northwest Territories, with lab work to understand potential downstream mobilization of carbon, nutrients, mercury after thaw or wildfire. Reach out for more information, and please send on!

Meanwhile, in France nearly everybody takes the entire month of August off every year.

Just tree ring-dated this wonderful sample (5.38 to 5.06 ka) and it appears that Ötzi lived (and died) during the lifespan of this tree! 🥰⌛ Quite moving to imagine Neolithic hunters seeking shade under its branches, on the way to a pass crossing 🌲👣🏔️ Likely same glacier advance buried them both! 🧊

Hi folks. Would anyone in a coastal part of the world be willing to send me a couple disks (cookies) from driftwood? Would like some cut from near the center of the driftwood & 15cm diameter. Crowd sourcing some samples for an experiment one of my students wants to run. DM if you want to help out.

More than 450 million Europeans. 29 countries. 1 shared freedom. In 2025, we mark 40 years since the Schengen Agreement was signed. This landmark event has reshaped how over 450 million Europeans live, work and travel.

Plants are facing the #heat – from molecules to the biosphere –but predicting their responses isn’t easy. New @science.org paper w/ @mekevans.bsky.social & Jia Hu shows how plant responses to #warming can shift or reverse across #scales, and how new research can improve prediction. shorturl.at/mQB2c
