Let's ease up on the hyperbole a bit, shall we?
While it's definitely hot in Phoenix, the current temperatures are neither "apocalyptic" nor "record-shattering."
According to Weather Underground here are the actual, average, and record temperatures for the past week in Phoenix:
*September 23: 97 actual, 98 average, 108 record (1982)
*September 24: 104 actual, 97 average, 108 record (2002)
*September 25: 103 actual, 97 average, 108 record (1979)
*September 26: 105 actual, 96 average, 108 record (1989)
*September 27: 104 actual, 96 average, 107 record (2009)
*September 28: 104 actual, 96 average, 108 record (1992)
*September 29: 103 actual, 95 average, 107 record (2003)
Not a single record broken, and while the temperatures are above-average, it is by less than 10 degrees.
