30 years ago evidence of substantial warming from ground 
based weather stations was lacking even in your own 
state of Arizona. This graph of average annual temps in
Arizona 1895-1975 shows a stable or cooling trend
even though atmospheric C02 was rising during that period:

Yes, your own state of Arizona warmed after about 1985:

Can anyone explain, with high confidence, why Arizona was 
hotter and drier around 1895-1905 as compared to around 1965-
1975? If not, then can anyone reliably predict, with high
confidence, how warm and dry Arizona will be in 2020 or 2050?
If not, then can anyone claim, with high confidence, that
the cooling and warming trends we have seen in Arizona
over the past 115 years have anthropomorphic causes?

On Oct. 6, 2010 Harold Lewis, emeritus professor of physics
at the University of California, Santa Barbara wrote this:

"For reasons that will soon become clear my former pride at 
being an APS Fellow [American Physical Society] all these years 
has been turned into shame, and I am forced, with no pleasure
at all, to offer you my resignation from the Society. It is of course,
the global warming scam, with the (literally) trillions of dollars 
driving it, that has corrupted so many scientists, and has 
carried APS before it like a rogue wave. It is the greatest 
and most successful pseudoscientific fraud I have seen in my
long life as a physicist. Anyone who has the faintest doubt 
that this is so should force himself to read the ClimateGate 
documents, which lay it bare. (Montford¹s book organizes 
the facts very well.) I don¹t believe that any real physicist, 
nay scientist, can read that stuff without revulsion."
