Grew up in coastal SoCal, and I'm still here. The houses here weren't even built with insulation. That said, climate change has been making it worse here. >90°F (>32°C) temps used to be extremely rare when I was growing up, but last year we hit the century mark a few days (~38°C). Obligatory: can't for sure blame AGW but more extreme events are likely. Just installed the window-mounted air conditioners today for this summer, because of the Texas-like combination of heat and humidity today finally made it uncomfortable. That said, don't discount California's efficiency rules and culture in our lower energy use, either. Or the fact that urban density is higher here so you don't lose as much energy to transportation.
