How many centuries to recover from the accumulated pesticides and other permanent pollutants? (Which have been the cause of the fastest and ongoing biodiversity collapse)

Good question. Nobody knows.

{...catastrophe comparable to the burst of the Deccan traps that killed the dinosaurs at the end of the Mesozoic...} ??? ...

What about the Chicxulub meteorite ??? ...

It helped, but it wasn't it.

Thanks for the broad overview, Ugo.

Sometimes other events might happen to interrupt equilibria and erode the softer limestone covering the lower portion of pyramids if oceans rise from periodic planetary rotational axis shifts (about every 6500 years) as hypothesized here, especially in article II, "Hidden in Plain Sight" https://theethicalskeptic.com/2024/05/23/master-exothermic-core-mantle-decoupling-dzhanibekov-oscillation-theory/

Chill down, please !!!

CO2 levels have provably been up to 5 times higher than current ones; see also the graphs in the post.

Before fossil fuels run-out, some smart ones will have either

- found new ways to convert other sources of energy into more usable forms or

- convinced most of the plebes to consume less, either by scarcity (pricing) or outright

ban.

Global war would be a more rude form of convincing the plebes to wake-up and get their act together.

Modern mass-societies will crumble relatively fast in high-density areas due to total interdependence and collapse of food-, energy-, transportation, social systems and soaring crime by the entitlement-addicted ones; which are far too numerous already.

Rural areas, where resilient, highly independent and self-reliant people live will suffer far less and survive. People in 3rd. world countries, who consume only 2% of the average US-citizen will not even notice the decline happening in the northern hemisphere.

So a gradual decline, depending on region, but never at once.

Many empires and nations have risen and collapsed, people moved to better pastures and survived.

Have a great time !!!
