Helpful and truly fascinating insights from bio-#archeology into human welfare and fate during changing climates https://www.pnas.org/doi/10.1073/pnas.2209472120
The authors of this meta study, 25 archeologists, discuss effects of the 400 year long cooling and drying event 2200 BCE / 4200 BP on human societies in India, Japan and Arabian regions.

Small, #sociologically equal -ish societies survived via flexible adaption politics and thru traditional knowledge of the environment and food options. Migration was low, ie not a necessity for this sort of social fabric.

Urbanites on the other hand, back then as today depended on trade for biological survival.
(The Order NOW button has become the sole traditional knowledge of survival skills which today's urbanites have honed 😁 )
Their societies were and are more unequal, prone to disease spillovers from poor to rich, and prone to violence outbreaks. The big #civilisation #cities in #India were emptied during the climate event 4200 BP.

The meta study above is part of a Special Feature by @PNASNews that discusses "challenges pertaining to dietary and nutritional quality and adequacy, resource inequality, interpersonal conflict and warfare, climate change, population trends, demographic transitions, migration, mobility, infectious disease and the rise of novel pathogens, and the transformative circumstances of human biology over the last 12,000 years." https://www.pnas.org/topic/547?utm_source=twitter&utm_medium=social&utm_term=pnasnews&utm_content=dd7ba597-eb00-4d4d-b704-24b56d063ae4&utm_campaign=hootsuite

The absence of solidarity in Western, US-dominated cultures / societies will be the cause for their quick and violent collapse before 2040.
Once our Order NOW button no longer works, our "traditional knowledge of the environment and food options", ie knowing timetables of commuter trains and location of supermarkets and car parks has 0 chance to be updated as quickly as then necessary for adaptation.

OTOH, cultures which still know how to make do with less, including MAPA, then have a good chance to continue and maybe, to even build on knowledge of our civilisation – because all fossil fuel use ceases then and the warming in the pipeline after true-zero by 2040 is negligible.

Emissions from dried wetlands and thawing permafrost will cause +0.2ÂșC per century, I reckon. That's slow enough for adaption by human organisation and the biosphere.
Also continued cooling from Earth's orbital factors #Milankovic also helps.

Am grateful to have read the meta study on archeological evidence of how human societies fared during the 400yr long drying event 4200 BP.
As layperson in everything climate-related, I experience a strong disorientation in philosophy, values and self-image since 2018.
Reading the study gives me back a bit of confidence in my common sense as it summarises what I intuitively felt-thought would happen to human-created systems during the rapid climate change we now face.

@anlomedad Layperson? Ich bin echt baff, dass du das nicht studiert hast. Was machst du denn dann beruflich?

IT eigentlich. Und in dem Leben davor war ich Beamtin im wissenschaftlichen Bibliothekswesen, erst Assistentin und dann auf FH-Diplom.
Beides irgendwie Informationsverarbeitung und -kuratierung. SchĂ€tze, das hilft n bissl, mir die unzĂ€hligen und faszinierenden Aspekte vom Ökoklimaklusterfuck anzueignen, den ich bis 2018 geflissentlich ignoriert habe, weil ich annahm, da wird sich schon jemand drum kĂŒmmern wie beim sauren Regen / Ozonloch.
