1) Local climate change is a constant every moment kind of thing. Global climate change is a century by century kind of thing. Does mankind affect the local climate? Yes, check out any large city, or even your own home. Does man affect the Global climate? Again, very likely, yes, much as do animals, worms, ants, grasses, trees and oceans. Does the Globe care that its climate may be being altered? Nope, the Globe does not even notice.
