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!

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:

Good news! The final ENTSO-E report into the Spain blackout is out A complex stew of different factors, but "too much solar" is simply not even among them, let alone a major component. As always: the narrative built by fossil/nuke advocates was wrong www.entsoe.eu/news/2026/03...

Summary
The final report of the Expert Panel on the 28 April 2025 blackout in continental Spain and Portugal identifies the causes of the blackout and outlines recommendations to strengthen the resilience of Europe’s interconnected electricity system. It was prepared by a technical Expert Panel of 49 members, including representatives from Transmission System Operators (TSOs), Regional Coordination Centres (RCCs), ACER and National Regulatory Authorities (NRAs), and was chaired by experts from two unaffected TSOs.

The investigation concludes that the blackout resulted from a combination of many interacting factors, including oscillations, gaps in voltage and reactive power control, differences in voltage regulation practices, rapid output reductions and generator disconnections in Spain, and uneven stabilisation capabilities. These factors led to fast increases of voltage and cascading generation disconnections in Spain, resulting in the blackout in continental Spain and Portugal.

Based on these findings, the Expert Panel sets out recommendations addressing each of the factors identified in the report to help prevent similar events in the future. These include strengthened operational practices, improved monitoring of system behaviour and closer coordination and data exchange among power system actors. The findings of the investigation also underscore the need for regulatory frameworks to adapt in order to support the evolving nature of the power system.

The 28 April blackout was a first of its kind event, and the recommendations aim to strengthen system resilience with solutions that are already technologically deployable. This blackout highlights how developments at the local level can have system-wide implications and underlines the importance of maintaining strong links between local and European system behaviour and coordination, while ensuring that market…

I may be—all the things you know I am, but I am not a killer! I have never so much as drawn a sword!” “No, You Have Not.
