Personally I'm skeptical of this theory that people have. I've researched it a tad and looked over the arguments for both sides and I personally don't see what Al Gore was trying to get at.
First, it was Global Warming and was happening alarmingly fast and Killamanjaro was going to have no snow on it by 2015 and Gore was leading the charge.
Now, its Global Climate Change, Killamanjaro is regaining snow caps (weird huh?), leaked emails from East Anglia CRU show cherry picking the "good data".
I'm just skeptical about how everyone jumped on the Global Warming train after Al Gore's video yet its never seen in the news about the leaked emails showing bad "scientific" methods and not allowing the controls/experiments to be retested (as the scientific process dictates).
Every now and then you see articles about how they were wrong and the scientists just modify their ideas and change the story.
I.E. The Killamanjaro snows have been increasing, as opposed to the prediction of decreasing alarmingly fast, but the scientists say yeah probably shouldn't have said that because we didnt really know what we were talking about then. But seriously the snow is gonna melt soon I can feel it.
Or
Phil Jones, lead scientist at East Anglia CRU, says in an interview that there has been "No significant warming since 1995". Well if there has been no significant warming since then....why did An Inconvenient Truth come out in 2005 and act like we were literally melting as we watched it? Why is it set in stone that the Earth is warming because of man and it will eventually cause disaster?
IIRC Earth has cycles of warming and cooling periods so where is the proof that this is not a natural occurence that we can neither aid nor discourage from happening?
So here's the deal:
You try to A) Convince me with real facts and sources that the Earth is warming significantly because of humans or

Convince those others that the Earth is not warming because of us or at all.
