Two great places for objective (should that have to be stated?) scientific information are http://www.discovery.org/v/30 and http://www.globalwarmingheartland.org/ . Also, consider going to the article “Environmental Effects of Increased Atmospheric Carbon Dioxide” at friendsofscience.org/assets/files/documents/robinson.pdf . At least read the Abstract, and consider reading the Summary (about 1300 words). Dr. Arthur Robinson at oism.org is one of the leading voices in this debate and a scientist’s scientist. (Consider subscribing to his newsletter Access To Energy - the best $35/year you can spend.) Arthur’s home-schooled son, Dr. Noah Robinson, presents the video lecture at discovery.org.
