Copenhagen Climate Concerns: Many people have expressed grave concerns about what was attempted to be accomplished when representatives of the nations of the world met in Copenhagen in early December 2009, seeking to acquire power to restrict the use of energy produced from coal, gas and oil in the guise of fighting global warming and averting the so-called climate crisis. Recognizing these concerns, we have posted a series of YouTube video vignettes in which various scientists and scholars present the reasons for these concerns. Post them on your own website or blog using YouTube!

4th International Conference on Climate Change
The Fourth International Conference on Climate Change will be held in Chicago, Illinois on May 16-18, 2010 at the Chicago Marriott Magnificent Mile Hotel, 540 North Michigan Avenue, Chicago. It will call attention to new scientific research on the causes and consequences of climate change, and to economic analysis of the cost and effectiveness of proposals to reduce greenhouse gas emissions.
