A satellite view captures the severe Sierra de Tamajón #fire, showing active flames, charred land, and dense smoke. Winds carry the plume far, dispersing it across the Mediterranean to the Balearic Sea, highlighting the fire’s extensive environmental impact.🌬🔥

The concept of trying to implement geoengineering solutions to #climate change is like trying to design a complicated, expensive, unreliable helmet while you're still hitting yourself in the head with a 2x4.

We do desperately need them to better understand past, current, and future climate change.

Especially since climate change has accelerated:

"Annual updates to ‘climate forcing’ data sets would allow simulations to keep pace as global warming accelerates."

Climate models need more frequent releases of input data — here’s how to do it

Massive clouds of smoke over large areas of Africa today, just south of the convective ITCZ belt, where the region is still in dry season, seen in the Met-12 True Colour RGBs. The green colour in the Cloud Type RGB suggests the smoke resides in the lower layers of troposphere 1/2

Se habla de que el abandono rural y la expansión de la vegetación han influido mucho en los incendios pero poco de cómo de disponible estaba esa vegetación para arder.

Si consideramos el índice de sequía SPEI a 3 meses, en zonas de Ourense o León estaríamos hablando de valores récord ‼️🍂

🔥 Emissions from Spain and Portugal #wildfires so far this year account for three quarters of 2025 total fire emissions for the European Union + United Kingdom based on #CopernicusAtmosphere data. As of 25 August, EU+UK emissions are the highest annual total in the GFAS dataset going back to 2003.

Evolution in fire danger due to climate change is of strong concern in Southwest France. The results highlight the strong benefits of reducing greenhouse gases emissions to limit the danger of wildfire.

🔥 Our new research in @science.org shows that people are increasingly exposed to fires globally, driven by overlapping shifts in where #fires occur and where people live.

But changes in exposure vary hugely by region and are shaped by different population dynamics.👇

🌡️La France a connu du 8 au 18 août 2025 sa 51e vague de chaleur depuis 1947.

Son intensité maximale est comparable à celle des épisodes d’août 2023, juillet 2022 ou juillet-août 2018.

Sur le Sud-Ouest les niveaux de chaleur ont parfois dépassé ceux de la canicule de 2003.
