I have become more knowledgeable about this subject this year, having done a fair amount of reading. One book I especially recommend is "What's the Worst That Could Happen? A Rational Respons to the Climate Change Debate" by science teacher Greg Craven. At his web site, www.gregcraven.org, one can order the book for only $10, and also watch his highly informative videos under the heading "How It All Ends." He speaks especially effectively, I think, to the climate change skeptics about why they should consider the potential consequences of doing nothing. His credibility spectrum and discussion of risk analysis are quite even-handed.
