If anyone is really interested in this topic I read a really interesting book that changed me from mildly starting to buy into man made global warming to a skeptic now. It features some world renowned scientists from all kinds of different fieldsthat lay out very compelling arguments against the prevailing view that the science is decided. Some of them challenge the idea that the earth is actually warming at all and others simply challenge the idea that if it is that man has much to do with it.
One quote that was especially powerful for me was from this guy who doesnt get much more qualified to comment about polar ice warming or lack thereof.
Dr. David Bromwich--president of the International Commission on Polar Meteorology--says "it's hard to see a global warming signal from the mainland of Antarctica right now
