Yeah, this global warming is nuts!
High of 4 tomorrow in Des Moines, then the warm southern air moves in for a high of 13 on Saturday before back to 4 on Sunday.
Simple answer to Al Gore and all the other Chicken Little's out there: Conservation of energy, simple physics.
The Law of the Conservation of Energy states"
Energy may neither be created nor destroyed. Therefore the sum of all the energies in the system is a constant.
Heat is a form of energy; therefore as others have said before me, the planet is not getting warmer as a whole. Some areas are getting wamer, while others are getting colder. The amount of heat is not increasing, it merely shifts from area to area.
I guess since he inventer the internet, now Al Gore thinks he can erase the laws of physics!
Bottom line: Parts of the earth go through cyclical temperature changes of alternating heating and cooling. When one area heats up, another cools and vice versa. We're not gaining heat.
