Global warming is nothing but a theory, and there is ample historical proof that climate change is an ever-active and evolving change system.
Al Gore is a blithering idiot that doesn't practice what he preaches. You should see his utility bills. I have.
Al Gore'* sole purpose for taking on the 'cause' is because he needed an income from lectures. He has proven time and again he doesn't know what he'* talking about, he refers to global warming as a fact when the entire scientific community knows it'* nothing but disputed theory, and he doesn't practice his own preaching.
The internet'* pulicizing of Global Warming has fooled alot of people into thinking it actually is proven and exists. It is NOT proven, and is unknown for whether or not it exists.
