But... climate changes can do more than hot and cold, this all aspects of the enviorment and it's a living chain.

My point is... climate is getting pretty weird, down here in Mexico, friday night we had thunderstorm, next mornig blue skies and sun, 11 am same day cold and rainy, then rain and hail, 3 pm sunny and hot, after that 6 pm freezing cold.... WTF... and all winter was sunny (not exactly hot but pretty sunny) no cold winter... so this things can change the natural balance and in some time it can do a lot of things to plants, and then animals and again wheather, and someday is gonna get us.

My theory is that the planet is fighting back... like any living organism, when something is harming you, you do something or your body does it so... why the planet should be any different.
