I have looked at those wind generators in Palm Springs area, and I am wondering if their presence could be altering the climate...as the wind generators extract energy from the wind, there has to be a change in the wind velocity, and resultant change of wind in areas adjacent the wind farms...conservation of energy, would apply...
A decrease in wind velocity, due the increased friction of the wind generators, would have to be followed with a increase in air pressure, eg, a high pressure area near the farms, and down wind....and as a thought, all these wind farms could be slowly the earth’s rotation....
