Phoenix increasing Rainfall in surrounding Desert?

Study indicates that cities in arid climates, such as Phoenix, may be creating an artificial environment that is affecting rainfall patterns in the surrounding desert.

A recent article on LiveScience explains how a new study is investigating how lawns, irrigation, man-made lakes, and thousands of pools have increased the annual rainfall by as much as 12-14% in the Northeast suburbs and rural areas of Phoenix.

The study was published in the online journal Journal of Arid Environments.
An abstract is available here.
