Stoff gegen die absurde „bei 40 Grad entzündet sich kein Wald“, Diskussion. Niemand interessiert sich für diese Aussage ist reines Ablenkungsmanöver, um die Diskussion zu versumpfen. Lesen!👇👇👇👇 taz.de/Forstwissens...

Forstwissenschaftler über Brände: „Der Mythos vom Brandstifter hält sich hartnäckig“

In Europa brennt es. Menschen müssen fliehen, manche starben. Forstwissenschaftler Alexander Held spricht über das Feuer und was wir dagegen tun können.

There's a similar paper out that deals with the Late Bronze Age collapse and the underlying causes of the mega-drought that set the fall of empires in motion. It's becoming clear that long-term natural variability can bring worse extremes than is commonly assumed. www.science.org/doi/10.1126/... 1/

Holocene ocean-atmosphere coupling and Mediterranean sensitivity to Atlantic circulation: Lessons from the Late Bronze Age collapse

Holocene Atlantic variability shaped Mediterranean drought risk through multiscale ocean-atmosphere coupling.

"Climatic conditions that caused the Great Drought and Global Famine arose from natural variability, and their recurrence, with hydrological impacts intensified by global warming, could again potentially undermine global food security." 🧪🌊 Link: https://doi.org/10.1175/JCLI-D-18-0159.1​

Drought extent and SST evolution: (a) Monthly evolution of the Niño-3.4 index, AMO index, and the Indian Ocean DMI during the Global Famine of 1876–78. The approximate beginnings and durations of dry conditions in major regions based on PDSI values (<−1.0) or seasonal rainfall anomalies (<−1.0σ), or a combination of both, are indicated by arrows and lines. Since PDSI from the regional drought atlases is annually resolved, the durations of drought in the regions identified based on PDSI (i.e., East Asia, North Africa, and Southeast Asia) are indicated for the 12-month period ending in the reconstruction season (i.e., September–August for MADA, OWDA, and NADA). Gray lines indicate seasons outside the main rainy seasons. (b) Extent of dry conditions (colored regions) during each of the three years based on negative PDSI (<−1.0; brown) or low rainfall (<−1.0σ; pink) conditions. Gray areas highlight the extent of the drought atlases, and white areas indicate absence of data. To identify the characteristics of dry conditions, PDSI values are from the regional drought atlases and rainfall anomalies (relative to 1901–50) are from the GHCN database. Note that the dry regions depicted in (b) are approximate and for illustrative purposes. Some subregions within the broader area depicted here might have differing conditions.

LOL, OK. Wurde wohl als "Intelligenzallergiker" bezeichnet, seh ich grad. Wegen meines Artikels, den diese Leute schon seit Jahren wiederlegen wollen, aber nicht dazu kommen, weil irgendwas ist ja immer. 🤣🤣🤣

One issue that will amplifythe climate effects even further is that land-use changes make the increasing heat worse. Among these are loss of wetlands and vegetation cover, which let water evaporate. Dry, open ground heats the air (depending a bit on albedo), so there's a kind of feedback loop.

Covering Climate Now@coveringclimatenow.org · 4w ago

Scientists are shocked by “super-extremes” in climate impacts as the crisis accelerates. “We’re starting to see extremes on a spatial scale and a magnitude that’s really surprising,” said Tim Lenton of the University of Exeter. By @eroston.bsky.social and @hayleywarren.bsky.social:

OK, I didn't see that coming. My new favourite #apocalypse is population crash because readily available AI "partners" leave people unable and unwilling to have relationships with people. Won't happen everywhere, but I think by now industrialised countries are probably toast.

Irgendwer aus Südhessen (oder Baden, Franken) mit Zeit für 'ne Gründungsversammlung, um damit einen neuen, kleinen CSD zu unterstützen? Der CSD würd in jedem Fall stattfinden, aber als eingetragener Verein wäre es sicherer, auch weils in der Umgebung mehrere Faschodörfer gibt. Näheres per DM.

Aus Gründen ist unklar, ob wir die wissenschaftlichen Whiskytastings weiter machen können. 🥺 Die restlichen (?) Termine: Düsseldorf, 12.9. 15 Uhr Online, 17.9. 20 Uhr Frankfurt, 10.10. 15 Uhr Stuttgart, 7.11. 15 Uhr Anmelden über diese eindrucksvoll zerschossene Sammelseite 🙄 (ggf scrollen)

Fun fact: The cartilage in your nose and ears is deformed by gravity over your lifetime. This is why older People appear to have bigger noses and ears. So if people really manage to enhance the human lifespan to several hundred years... Well, use your imagination. 😁

Ihr findet Elon/Jeff/Mark/Peter scheiße, aber gebt ihnen regelmäßig Geld. (Vielleicht wisst ihr es nicht.) Ihr findet Indieverlage gut, aber gebt ihnen selten Geld, weil ihr denkt, dass ihr euch das gerade nicht leisten könnt. Wenn wieder ein Verlag aufhört, denkt ihr: schade. Denkt etwas weiter.
