Seems to me, Man's ability to change climate must have reached "interplanetary" proportions.
I agree completely, the cyclical activity of the Sun is probably more responsible for the cycles of climate change on THIS planet than anything humanity can do.
Interesting aside;
Did you know that it has been recently discovered, as part of this solar cyclic activity, the Sun actually "shed's it's skin" ??
Note similarities to Ancient Indian (Native American) legends tying the symbol of Sun and Snake and "circle of life" together..
Sometimes I wonder how much those ancients "really" knew, and how they "knew" it?
They have SUV's on Mars? Geez...who's doing something sbout that?
