The question is not if the commenter is an expert, but if they are correct.
The claim that some models didn't take larger systems into account is also because an expert in the arctic wasn't an expert in oceans. And the expert in biodiversity isn't an expert in food supply chains. Expertise isn't the question. Instead it is - do all of us who are non experts (all of us) have enough expert data to have a systemic understanding of an accelerating trend?
On the internet the default pisition is not true/untrue; its, why should I acknowledge you?
If you are still trying to gauge truth before this, you are poisoning your mental heuristics. Thats why propaganda are ao effecfive: you can be told something is either, and it can still be effective.
Humans and LLMs are similar: the separation between input and commands is not a hard barrier.
So, back to GP: CLIMATE CHANGE is reversible. It just depends on whether we are talking about socipecnomics or physical processes.
Ya, I agree, but I am not familiar with the intimate details of present climate models, nor am I planning to be. I can't/won't directly evaluate whether the argument they present is correct. But if _they_ are familiar with the intimate details of present climate models (ie, if they are an expert), I will tend to trust them more.
