Parallèlement, des experts forestiers s’étaient penchés sur les implications de ce phénomène pour les forêts, dans un article également publié il y a 36 ans : « De nombreux auteurs (par exemple…) affirment que des changements dans la fréquence et la répartition saisonnière des feux de forêt sont probables en raison du changement climatique induit par les gaz à effet de serre. La fréquence et la gravité des feux de forêt devraient augmenter sur la majeure partie des terres non gérées, en raison de l’augmentation prévue des quantités de combustible disponible liée à la hausse de la productivité primaire, ainsi que de l’accumulation accrue de combustible mort résultant d’une mortalité accrue. Dans les zones forestières où l’humidité du sol diminue, le dessèchement des combustibles forestiers s’accentuera, augmentant ainsi la quantité de combustible disponible. Fried et Torn (1988) ont comparé les variations de la superficie brûlée dans des conditions climatiques actuelles et dans un scénario de doublement des concentrations de CO₂ dans la Sierra Nevada, en Californie. Ils ont constaté que, dans ce scénario climatique modifié, le nombre d’incendies de taille modérée (quelques centaines d’hectares) serait multiplié par deux et celui des incendies de plus de 1 000 hectares par trois... » https://www.ipcc.ch/report/ar1/wg2/

«La France n’est pas prête au climat d’aujourd’hui et encore moins à celui de demain» : l’alerte de 26 scientifiques https://www.lefigaro.fr/vox/societe/la-france-n-est-pas-prete-au-climat-d-aujourd-hui-et-encore-moins-a-celui-de-demain-l-alerte-de-22-scientifiques-20260629 En marge d’une rencontre avec Giorgia Meloni, Emmanuel Macron a affirmé qu’on ne pouvait pas s’adapter «à un pic [de chaleur] qui n’a pas d’équivalent aujourd’hui». Vingt-six scientifiques lui répondent. Non seulement ces records étaient prévisibles, mais ils seront battus dans les années à venir, expliquent-ils. 1/6

Just in case Europeans think that the air here is hotter than usual, do not forget that the sea surface of the entire planet is warmer than it has ever been in late June (since records began). https://pulse.climate.copernicus.eu/

Sorry, here is a specific #trainbubble question: I am trying to have my bike on trains between Hamburg and Hirtshals on Sep 12. Being on the ECE 398 (Hamburg-Copenhagen) up to Kolding would be great, but... 1) DB first offers to reserve Hamburg-Kolding (or else Hamburg-Copenhagen) and then says "Reservierung nicht möglich" 2) DSB does not allow to book or reserve anything earlier than 2 months before departure 3) If I try DB, but only Hamburg-Padborg, it says "Stellplätze ausgebucht" Anyone has a trick for getting the bike on that train? I know there are earlier trains, but I may or may not make a connection earlier that day, and the ECE398 would be my last chance to make it to the ferry in Hirtshals that day. And having it in a bag (as I have done once before) is also not an option for this trip.

Good morning! Leaving for another half-work/half-leisure, half-train/half-bicycle trip this morning, to Switzerland and it's neighbors. Luckily the worst of the massive heatwave seems to be over. Actually the weather seems perfect for now. The plan is to take four regional trains today and start attending a conference at UNIL ("Towards a just and habitable world: Exploring the role of technology") in the afternoon. #topoftherhine2026 1/n

@rpolenz Herzlich willkommen! Ich bin vielleicht zu optimistisch, aber wenn noch mehr engagierte Menschen hier im fediverse sichtbar wären, dann hätte das garantiert eine positive Wirkung auf die öffentliche Debatte.

@rahmstorf@fediscience.org Gut gesagt: "Er bietet den Wählern, die spüren, dass 'ihre Welt' verschwindet, ein kulturelles Trostangebot. Der Begriff 'hocheffizient' ist dabei keine technische Beschreibung für einen Motor. Er ist eine therapeutische Intervention. Er signalisiert dem verunsicherten Facharbeiter und dem Dieselfahrer: 'Keine Sorge. Du musst dich nicht ändern. Dein Leben, dein Status, dein Auto – alles bleibt gültig. Der Fehler liegt nicht bei der alten Technik, sondern bei den Grünen, die sie verbieten wollen.' "

If it was not clear before, then it is now. Every single well-meaning post on that hate speech platform is direct support to the extreme right in several European countries. No public institution should be posting there.
