I don't make any sort of claim of 'just fine'. I am saying there will be places and times where people cannot regulate their body temperature via evaporation, so they will die outside without AC within hours. And in Singapore that point hasn't been reached yet. The point isn't that it's "just fine" right now, it's that it will get way worse.
