Why would you think the drought will last for generations? Some

The historical/geological record shows these long cycles
http://tinyurl.com/md969j8 . Seems to have been what
happened to the Mayans http://tinyurl.com/m8wnyzu

peoples. Moved in and prospered during the wet half of the
cycle and had to leave when the dry half of the cycle hit,
and it lasted for generations. Many southwest residents may
may well have to do the same.

FWIW human activity *MAY* be exacerbating/accelerating the
conditions causing the drought, but given that these
"mega-droughts" have occurred several time in the past, as
indicated by the tree rings, clearly it cannot be *THE*
cause. http://tinyurl.com/myt5lkk

Its dustbowl time again, but this time the Okies are moving
