Global Warming

Global Warming or global cooling. Al gore says we are killing the planet and need to limit carbon dioxide emissions. Gore makes a lot of claims and talks of the experts who he follows, but dose not list all their credentials. he drives a limo to the seminars by himself and lives in a huge mansion that waste a lot of energy. Whats his greenhouse footprint? Then came professor Klesit who says we are in a cooling faze of the planet. well I am not a very educated man but from my geology classes i can tell that this planet has been through a lot of changes in the past from meteor strikes to several mass extinctions of all speci. Maybe the earth has a way of starting over and maybe we will be extinct one day but not from our own hands. Unless we use our nuclear weapons on each other.
