Pretty unambiguously garbage, yes.
AC is in no way mentioned in the linked article or the Call to Action that identifies "4 critical areas of action on caring for the vulnerable".
You unearthed a PDF where air conditioning is mentioned in a QA side note, here's the part you omitted:
> Why doesn’t the WHO just recommend wider use of air conditioning?
Air conditioning (AC) is not a sustainable (in time or environmentally) societal solution for reducing
hazardous heat exposure. It is inequitable and unaffordable for those with low incomes; it increases
energy demands and heightens the risk of blackouts; it may promote individual and societal
dependency and overcooling, and may impair heat acclimatization; and it contributes to both the
urban heat island effect and climate change, thus worsening heat exposures in the medium and long
term.
So maybe, if you are lucky, they allow AC for the most vulnerable with a special exception.
Does this stance sound to you like the UN is making the necessary recommendations to roll out AC widely to protect people?
They are not nearly doing enough. It's like they are not even trying to do their job. I am honestly disgusted by how pathetically incompetent they are.
