"The carbon opportunity cost of animal-sourced food production on land" #Hayek et al 2021
When all animal pasture and crop land currently in use for animal agriculture are rewilded, the process removes a total of
358 to 743 GtCO2 from the atmosphere by year 2050.
-743 Gt CO2, that's the theoretical equivalent of 0.5°C. ^^
The CO2 removal is based on the biomes originally covering the land nowadays in use for animal agriculture.
Ecosystem soil and litter could remove an additional 225GtCO2, "but this estimate is highly uncertain".
Albedo changes were not included in their modelling; but they say, regrowth of temperate forest systems increase temperature locally – but globally, they net cool despite albedo loss.
"Carbon uptake saturates after around 25 years for tropical forests
and around 30 years for temperate forests." Good to know. I had guesstimated this takes 60 years.
From what I can see, they computed only the rewilding process, not the CO2-equivalents GHG emissions like CH4 and NO2.
But reductions in those are maybe balanced by increased microbe activity via changes in hydrological cycle. So I won't bet on additional temperature decrease from them.
My proposed #RCPcollapse scenario research has to include rewilding in all the settlements and agriculture land in the highly tech-dependent societies, and in cities in all societies.
Also, outgassing from land and ocean once CO2 concentration drops reduces the effective atmospheric drawdown from 743Gt to 558Gt CO2.
Still -0.4°C.
-0.4°C within 30 years or so.... from the end to animal agriculture alone.ß!
Shocking. But to remind myself: from 2005 to 2020, global °C rose by 0.4°C.

This is one of my favorite climate graphs (I like the graph, though not what it tells us).
It shows ~800,000 years of natural variability of global atmospheric carbon dioxide (from the Vostok ice core data), plus the last few decades, when CO2 levels have skyrocketed from human activity.
It shows definitively how humans are driving current climate changes, far outside natural variability.

Movie time! 🍿Watch the CO2 drama unfold to the climate emergency. With flashbacks into the distant past, this crime story is a real killer.

@efesce@eupublic.social Und außerdem: dieser nationale Bauchnabel bringt nicht den Wandel, den es braucht. Wir müssen einen Weg vorangehen, der von mehr Staaten adoptierbar ist. Einen Weg, der auch aus dem Rohstoffengpass heraus und in die planetaren Grenzen zurückführt. Und der bereits beinhaltet, dass Zeit und va.

Denn: Energieerzeugung ist nicht alles, auch wenn Tech-Affine das gerne glauben mögen. Und Post-Growth implementieren geht nicht im laufenden Wachstumssystem mit seinen Interdependencies, auch hinein in soziale Abhängigkeiten hinein Stichwort RentenFonds.

Jau!
die EU-verbundenen Staaten, deren Kerosinlieferungen noch nicht wieder vor-Pandemieniveau erreicht haben.
Die dämlichen Fluggesellschaften sollen dichtmachen und Busfahrer werden. Da werden sie gebraucht.

Schon unterschrieben?
Offizielle EU-Petition für pro-Kopf-Rationierung von Flug-CO2.
Angefangen wird mit der Menge, die für 1 Hin- u Rückflug Frankfurt-Oslo reicht. Dann jedes Jahr weniger.
Man kann seine Ration auch verkaufen oder sparen oder einfach nicht nutzen.
Wenn alle diejenigen unterschreiben, die auch die Petition #TaxTheRich für den dt Bundestag mitgezeichnet haben, hat Deutschland hierbei sein Quorum fast erreicht. ✊🏽
Österreich hat bisher 127 von 13395 Unterschriften geschafft. Da ist auch noch Luft nach oben !!
