Based on what I see and read, and in spite of the many attacks on Al Gore's laudable effort to help inform the public, there is a consensus that global climate change is real and caused in part by humans. The forecasts for future emissions cinch the debate. http://www.ipcc.ch/ From a political point of view the debate is over. While it is true that the minority of skeptics who remain should continue to challenge the consensus as they see fit, this does not speak to the logic that governs our political actions. Obviously there can never be one-hundred percent certainly about something as complex as the future of our global weather, however given the risk to humanity, and now with what appears to be an overwhelming consensus in the scientific community, I can see no reason why any debate about "if" should remain in the public domain. This is a question for the minority of scientists to pursue, not Joe Sixpack. In short, it is crackpottery to publically peddle the arguments for doing nothing. There is no logical justification based on any risk to benefit ratio that you wish to consider. The most irresponsible and selfish action, or lack thereof, is to doom all future generations for nothing but ego. If the publicly vocal skeptics are wrong, what price should they pay for interfering in what may be humanity's last hope to avert a global disaster? There is no justification. In fact, consider why they even make their debates public? Clearly the reason is that other scientists don't agree. Crackpottery!!! They are trying to bypass the scientific process for a political one because they stand alone. Also, the economic benefits of green technologies are many-fold; the economic gloom and doom arguments used against green technologies are based on dull thinking that ignores issues such as the tremendous health costs associated with fossil fuel use, the military industrial complex and the history of US military action in the Middle East, jobs created by green and domestic energy solutions, and efficiency gains to name a few. Consider for example that Wal Mart just opened their first high efficiency store; not out of concern for our global health, but because they are the nations largest user of electricity. It made economic sense to save energy. See, no gloom and doom. Green pays.
