    “the tipping point that makes an Amoc shutdown inevitable is likely to be passed within a few decades, but that the collapse itself may not happen until 50 to 100 years later”

    Long enough that everyone who got us into the mess will be dead and won’t have to suffer the consequences or admit they were wrong. 😑

      The presumption in their work is that ClimatePunctuation isn’t accelerating.

      That presumption is pervasive, among climate research.

      It’s wrong.

      The actual speed of ClimatePunctuation is bell-curved, more or less:

      • speed-of-change from the pre-existing Equilibrium is small, at the beginning…

      • speed-of-change increases, to a maximum…

      • speed-of-change decreases from the maximum down to the new Equilibrium.

      Obviously, the evidence which keeps falsifying the optimism of the climate-research-field’s models is evidence of accelerating process ( the deep East Antarctic ice-sheet being warmed 2x as quickly as models predicted, e.g. recently-published )

      That such evidence KEEPS getting in our face, & we KEEP ignoring that we’re getting the whole-speed-curve wrong, is evidence that paradigm-bound-thinking is overriding our ability-to-survive.

      ClimatePunctuation’s still accelerating.

      IF the people who reject that are predicting 50-100y before it becomes inevitable that it shuts down, THEN ClimatePunctuation’s accelerating is GUARANTEED to produce the result sooner, because they’re predicting based on the wrong curve.

      It doesn’t matter, though: accountability/integrity isn’t something that’ll ever affect institutions, it’s powerless against them, right?

      Our kind protects what’s most-important, & … nonaccountability is the 1st thing we protect, before our very lives.

      All the last few thousand years of history backs that fact.
