I think we may be able to nudge it on occasion, but the changes the earth is experiencing is, IMHO, simply part of the overall natural cycles of the earth. Space weather also has an influence, I think.I was thinking and I would like to have everyone "2 cents" on this. With the wacky weather that we are having lately, Did the Russians "hacked" Harp in the great state of Alaska? Or is it just global warming/cooling? or is it just normal weather that affects us all?
