Against my better judgement, I'll link you Here.
If you anyone actually cares to learn about climate related data, how it is kept and graphed, and why there are so many discrepancies, you can find it by really reading and studying sites such as this one.
Though at the same time, if you are similar to the media and environmental groups, you can search through this site, find a graph that looks like it supports your ideology, blow it up, and show it to the world as proof of Armageddon.
The facts are out there, but they are buried in so much speculation and bias that it is hard to know what to believe. I don't claim to know all the facts, but I do claim to have actually come to my own conclusions based on my own amateurish research. Certainly nothing to brag about, but much more than most people do.
