depend on this water for daily use as long as (1) predictions
of climate change models prove groundless, (2) the kind
of droughts documented by tree rings and
other records
of past climate disruptions don't occur, and (3) the cities
of central Arizona don't grow so much that they consume their agricultural buffer, their main protection against uncertain years ahead.
