Excerpt from The Skeptical Environmentalist Replies: http://www.sciam.com/article.cfm?articleID=000001E0-157B-1CD4-B4A8809EC588EEDF&pageNumber=1&catID=2 The Kyoto Protocol will do very little good%u2014it will postpone warming for six years in 2100. Yet the cost will be $150 billion to $350 billion annually. Because global warming will primarily hurt Third World countries, we have to ask if Kyoto is the best way to help them. The answer is no. For the cost of Kyoto in just 2010, we could once and for all solve the single biggest problem on earth: We could give clean drinking water and sanitation to every single human being on the planet. This would save two million lives and avoid half a billion severe illnesses every year. And for every following year we could then do something equally good.
