people are complaining about the heat in californiaï»¿ because it's so dangerously high.  it's not that they're complaining unnecessarily.  it's a rather justifiable thing to worry about.  if you were there i'm sure you'd be sick of three solid weeks of above 100 F.  that can be not only dangerous for health, but also terrible for the environment (with the amount of energy spent on air-conditioning).  it's something significant.
