Been spending 3 months each winter here for 12 yrs. Always enjoyed great weather. Even during the cold spells always sunny & if the high is 50 it feels like at least 60 in the sun.
We're in Mesa which is higher & have never experienced severe air pollution. Seldom see visibility less than 10 miles.
Personally I don't believe the global warming scaremongers (dependent on govt grants & subsidies).
There are credible reports that b/c of reduced solar flare activity, we could be entering a mini ice age.

Can't see how 125 degrees is healthy and its only going to get worse 140 degrees and more

I lived there for one year after graduate school. I had a terrific job, but it was absolutely hellish living there.

I cannot imagine ever considering living there. Why do so many people go there. It used to be a place for people with allergies to go that had a dry air. Now, so many have moved there the air has actually gotten more humid. It boggles my mind what people find so attractive about this city.
