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:

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

'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"?

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…

Fascinating and a bit puzzling (but good) that quite a signficant chunk of those supporting Trump and opposing Biden must also think climate change is both a problem and man made. Suggests that not all Trump supporters buy into the climate denial that is rife in RW social media & media.

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.

I agree but UK + Europe may have no choice but to at least reduce their dependence and start building up its own infrastructure, at least for the most critical services. If the US remains potentially hostile it will be very difficult for UK and Europe for quite a long time though.
