Height does not impair the hydraulic system of the tallest tropical Dipterocarp trees www.science.org/doi/10.1126/... - good to see our #MetabolicScalingTheory predictions we made for scaling of hydraulic resistance and xylem anatomy hold up in some of the tallest trees #allometry #megabiota 🧪🌾🌐

Height does not impair the hydraulic system of the tallest tropical Dipterocarp trees

Half of the aboveground biomass in forests is stored in a disproportionately small number of very tall trees. These giants are predicted to be more vulnerable to drought-induced damage because height ...

Fires in France have now burned over 91,000 acres, by far the most of any year since the satellite record started in 2006. Current area burned is about 34x larger than this date in a typical (median) year:

New study published last week: Northern high latitudes could become a net carbon source below 2 °C global warming 🌍 See more here: doi.org/10.5194/esd-... With co-authors Eleanor Burke, Dan Hooke, @njsteinert.bsky.social, @mathisoncamilla.bsky.social & Luke Smallman.

Northern high latitudes could become a net carbon source below 2 °C global warming

Abstract. Under historical warming, terrestrial ecosystems within the northern high latitudes have been a net carbon sink, providing vital mitigation against anthropogenic emissions of CO2. However, t...

Why do some plants open their stomata at high temperatures? Our new paper shows that this behaviour is optimal, and a crucial thermoregulation strategy. 🍃 However, this only emerges when the leaf energy balance is fully integrated in the optimisation. This is missing from global models at present!

Stomatal Decoupling From Photosynthesis Under High Temperatures Is Consistent With Stomatal Optimisation

Many leaf gas exchange models predict that photosynthesis and stomatal conductance are tightly coupled and respond in parallel to changing environmental conditions. However, experiments show that whe...

Something deeply troubling & shocking is happening at Exeter University*, where a mass cull of staff is planned, even though it's in surplus. No good justifications given. @jamesgdyke.info provides the details: www.technosphere.earth/the-bonfire-... *Disclosure: I have a Visiting Fellowship here. +🧵

The bonfire of the humanities

150 academic posts at the University of Exeter are to be cut, most in the humanities but also in social sciences, engineering and environmental sciences

technosphere.earth

Excellent open letter from the Exeter Lib Dems to the university about the proposed cuts. Really good to see us standing up for Unis as part of our community

Studied at Exeter for my BA/MA (History & Classics depts). Top of the line teaching and research, interlinked. Exeter remains one of the most productive UK universities in my own fields (early modern, social, maritime history). If Humanities here is up for cuts then what university is NOT at risk?

🚨 PLEASE SHARE WIDELY 🚨 If you are an Exeter alumnus, and wish to express your horror at the proposed cuts to the Faculty of Arts, Humanities and Social Sciences, please sign the Google Doc petition below. Not an alumnus? You can still help by signing the Exeter UCU petition at c.org/msXfsb2g5b 🗃️

'What is perhaps remarkable about the Exeter cuts is that they are targeted at some of the university’s most successful departments, many of which turn over a profit even after they have made enormous and increasing contributions to the central university budget.' Read, rage and weep.

The Crisis in Britain’s Universities

The cuts that have been proposed at the University of Exeter demonstrates the crisis of purpose in Britain’s universities. Should not universities also be places to prepare for "eternal dwellings"?

Oh no! @thedisproof.bsky.social what happened over on the hellsite?!

If a strong El Niño develops in 2026 (quite likely now), the main effects on global temps will be in 2027. This is because there is historically a lag of about three months between when El Niño peaks (generally in Nov/Dec) and when the biggest effect occurs:

🚨BREAKING🚨 The most recent RELATIVE Oceanic Niño Index (RONI) forecast shows we could be facing the strongest El Niño in observed history!! This could lead to dystopian global climate change impacts over the next 1.5 years. No one is prepared.

The US is threatening to invade a European country 🇪🇺. One small way to resist: use European alternatives to US big tech: european-alternatives.eu

This is the critical problem. By relying on US tech and trade we are almost totally trapped as a vassal of the US. UK plus Europe needs to rapidly start separating itself from the US and plan for the long term without them.

In a new article over at Carbon Brief, I explore why the past three years – 2023, 2024, and 2025 – have been exceptionally warm. The main culprits turn out to be a combination of El Nino and internal variability, declining aerosols, and a strong solar cycle: www.carbonbrief.org/...

The true question right now is whether you believe in the moral character of the British public. If you do, you'll want to have the fight with Reform. You'll believe that the public will hate the idea of breaking up families, spying on & deporting people who've worked here for years.
