Amazing work and really cool stuff! But the 1st point on the “four hedges” was a little disappointing for me. Humidity is a crucial interference to temperature; and if you had analysed cities with that parameter you’d have gotten completely different results. Being Brazilian, I’d def say that Rio de Janeiro is a place where you need AC, not prefer it — mainly because 30ºC there feels like 36–37ºC so very often and you sweat loads.
