I have no evidence, but I posit that this is Northeast population center/media market bias at play. Personally, I see far more people saying things like "how can you live there" about cold places, than about hot places (in the US). However, the majority of the population in the US lives in areas that are less habitable due to cold than they are due to heat. That is to say, a New Yorker or Bostonian readily identifies with needing heat to survive, where they don't as readily identify with needing air conditioning to survive. So, extreme heat is more "foreign", more "other". Also, in the US, air conditioning is more of a comfort factor than a life-sustaining factor. I mean, sure, there are places in the desert that are only habitable due to A/C, but there are just as many places across the south that are miserable in the summers, but people lived there 100 years ago, all the same.
