I understand it if your eyes glaze over whenever you hear the term "anthropogenic global warming." Only geeks and scientists spend time delving into the nuances of solar cycles, CO2, ice cores and the like. But here's why you need to at least a little bit about what's going on.
First, you want to follow the money (hint - look hereand here for examples). But this is just the tip of the iceberg (it's not the melting kind). For example, George Soros wants to get the International Monetary Fund involved. Then, there's a queue of nationswhich want to shake out a few more billions. But these funds pale in the face of carbon cap & trade schemes which have already fattened Al Gore's coffers.
Keep these in mind the next time someone tries to tell you that skeptics and deniers are "in the tank" for big oil. Big oil has invested a paltry few million for research but if you dig a little further I think you'll find that, like many big corporate entities, they sprinkle a little on both sides in order to have friends in high places no matter who prevails. They're not ideological, just fiscally prudent.
But wait, there's more! Money isn't the sole reason scientists would sell out. Most would be offended if they were even suspected of selling out so cheaply. But give them access to power and now you have a recipe for compliance. If the U.N. prevails in this debate then they get to become the high priest of the world and the scientists get to be bishops. I can't totally blame them for not recognizing the path they're on since they study science instead of humanity. Many have even convinced themselves that a trace gas like CO2 is enough to force the climate to change which just makes them even more useful as pawns in the hands of the power brokers.
The bottom line: The earth may or may not warm but it will do so in spite of, not because of mankind (cooling is more likely and far more deadly). But when a world government tries to reduce everyone to the lowest common denominator, the suffering of the people is guaranteed, rain or shine, hot or cold. That's one thing that is "settled science" throughout history.
