yes! why is it surprising that climate change is not linear?
i get that we dont know the exact cause of this dramatic & sudden rise, but i'd guess many assumptions have been made about proportional effects
and ofc, we're carrying more CO2 in the atmosphere than earth ever has... a look at the record shows that historically, it was a much hotter planet when CO2 levels were anywhere near this high. maybe things 'catch up' in fits and starts

Because @rahmstorf has been part of the climate modelling community for decades and of course the models aren't in any way simplistic. If a central climate scientist says he is worried, because Earth got much hotter than expected and modeled ... then maybe it's worrisome. Extra worrisome.
@knud even the experts dont know everything. there will be unknown unknowns in climate change. as a scientist myself, i know they often tend to be *conservative* w opinons to reach consensus. ofc theyre now scared - we may be fckd
it's not possible to 'worry' a person like me anymore, who was worried back in the 90s & 00s. i didnt have kids, who would be adults now, in anticipation of a climate crisis. now, i'm just living my best life, expecting civilization might last until about 2050
I don't like "doomer" behavior. It's just another excuse to not become active.
It's us, it can be stopped.

Sure, but one needs a decent argument to choose a quickly diverging function over a linear one, no? So yes, one might get surprises, but in the end this means a physical mechanism or coupling that wasn't on people's radar so far. To find and include that will be important.
