  • Sometimes it's better to keep the mystery unexplained.

A new study of desert plants living on the slopes of Arizona's Santa Catalina Mountains has uncovered a startling fact: many trees and shrubs have moved a long way up-slope over the last 50 years. The shift could be caused by a warming trend in recent decades in the Arizona desert, or perhaps the 20-year drought.

No, if plants grow then there must be water underground and with the sun. So no is the answer

There must be water somewhere is the right answer, many desert plants condense their own from the humidity contained in the air. So rising temperatures could be a very valid explanation.

A 20-year drought? No wonder the plants are moving elsewhere.
