We just published the Global Carbon Budget 2025, with a mix of bad news (CO2 emissions continue to grow) and encouraging news (35 countries saw emissions decline over the past decade while growing their economies).

Hydrology Paper of the Day @dukesjeff.bsky.social on plant hydraulics in Earth System Models: challenges with capturing complexity and spatial variability; water stresses and transpiration in the context of drought and species-specific ecology; the challenges of scaling; and testing new models.
Just published this new paper, with a bunch of fantastic colleagues, with many suggestions for "Improving the representation of plant water stress and water use in Earth System Models." Access is free online. We have some great figures, thanks to Victor Leshyk. 🧪🌐🌳🌎
