I know that there are people out there who don't believe in global warming, or who believe that it is cyclical and not something to be worried about. I am not one of those people. However, for the people who don't believe in it, I have this to say:
Why not act as if global warming is real anyway? All of the ways to counteract global warming are good for the planet in other ways. Many ways of combatting global warming (CFLs, unplugging things, driving a more fuel efficient car...) save you money!
So just act like it's real and follow the steps whether you believe or not.
