Greenhouse forcing:
"We find that the likelihood of the occurrence of climate regime shifts significantly increases in the context of super El Niño events due to their remarkable climate perturbations. This higher probability is detected across various climate elements, such as surface air temperature, sea surface temperature, and surface soil moisture. In addition, we suggest that this boost effect of super El Niño events on climate regime shifts will be greatly amplified under future greenhouse warming."

"Closely spaced or overlapping El Niño events create cumulative cloud suppression. Each El Niño phase actively reduces low-level stratocumulus and trade-wind cumulus clouds over vast tropical and subtropical ocean areas as part of the Bjerknes feedback loop. When the next El Niño develops before full cloud recovery during intervening La Niña or neutral conditions, the albedo loss becomes progressively more persistent, producing the observed multi-decadal linear decline. […] Major El Niño periods (especially 2015–16 and 2023–24) coincide with accelerated albedo drops and incomplete recoveries."

The Chicxulub Craters and the Anthropocene Holocausts were choosing players. Of course the Craters chose a massive asteroid to be on their #side. The Holocausts countered by choosing fossil fuel consumption. Then the Craters chose massive volcanic eruptions, so of course the Holocausts chose aquifer depletion. They met the Craters' acidified oceans with thinning sea ice--and so it went.

It's going to be the extinction match of the ages.

AIUI biologists have repeatedly observed that when a species overpopulates it's environment one or more events result in a crash in the population numbers of that species.

I think that #ClimateChange, #MassExtinctions, and #GlobalPandemics show that humans have overpopulated the environment.

We've had a chance to avoid a population crash by implementing smart solutions.
But our culture has messed with our politics and our science and no adequate solutions may happen

Hi,
I have recently updated my UN 🇺🇳 radical reform petition, and I say a little more about #MassExtinctions, including, possibly, of human beings.

For you or anyone else interested, the petition is accessible via toot:

Hi Nonya,

Yes, extinction is a sad affair.
