This is why cities need trees. Hard surfaces and parked cars can reach extreme temperatures, while shaded grass and tree-covered areas stay dramatically cooler. This is the urban heat island effect in one image: hard surfaces absorb and radiate heat, while vegetation and shade reduce it.

Don’t forget what REALLY “drives” a lot of regional growth and infrastructure politics. It’s pretty much this. Great drawing via Ian Lockwood.

When it comes to the energy transition I'm a glass half full person. I know: plenty of people would say that's terribly naive. They point to the scale of the challenge. They point to vested interests. They point to hard-to-abate sectors. And they're not wrong. But here's what they miss. 🧵

“Copenhagen reported that 62% of its residents are now commuting to work or school by bike — an increase from 52% in 2015 & 36% in 2012, when the City Council launched a 14-year-plan to improve the quality, safety & comfort of cycling.” #Copenhagen chose. They keep choosing even better every year.

📢El #CSIC convoca 441 becas #JAE_Intro_ICU destinadas a estudiantes de grado y máster interesados en iniciarse en la investigación científica 🗓️El primer plazo está abierto hasta el 10 de marzo ➡️Más información: http://tiny.cc/n9qy001 ➡️Convocatoria: https://sede.csic.gob.es/icu2026

Last Wednesday, the village of Grazalema (southern Spain, 900 m altitude) received 577 mm of rain in one day: the second highest ever recorded in Spain, only behind the deadly downpour in the Valencia region of 29 October 2024. malagaldia.es/2026/02/06/g...

Incredible: ~2500mm (78 inches) in 20 days - 1.5X the normal yearly rainfall in Grazalema, Spain and it’s only February. How? A 5000 mile Tropical Atmospheric River lifted by terrain in Southern Spain. H/T Nahel Belgherze #europe #flood #spain #weather

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/...

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.

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!
