I highly recommend Greg Craven's book "What's the Worst That Could Happen? A Rational Response to the Climate Change Debate". He models the scientific method of seeking out those who disagree with us and asking them to persuade us otherwise. Meanwhile, he asks people who are climate change skeptics if they really want to take the risk that they're wrong, and drag humanity along with them over the cliff. You can order his book and watch his great videos at his website: www.gregcraven.org. If you know a skeptic, they might even be open to checking out what he has to say. Because he is a high school chemistry teacher, his work is also very appealing to the youthful and young at heart, being laced with humor.
