If you find the utter certainties of the two sides in the global warming debate confusing, this could be the book for you. Greg Craven is a science teacher in the USA so he knows a bit about his subject; more importantly, he doesn't harangue you or the various 'experts' on either side. He just takes you through a form of risk analysis in a humorous and highly readable way, asking the question that's on the front. Unlike one of the other reviews of this book you can read here, he doesn't set about rubbishing people's ideas but does apply a degree of varied weight to them, using a set of criteria he's chosen. You don't have to adopt the same criteria, and he's anxious you avoid some normal preconceptions humans fall for, so you get warned about 'red flags' - the first of which is our tendency to look only for evidence to support our own views.
I saw some of Greg Craven's rather whacky videos on You Tube so I was interested that he'd taken the debate he'd been having online into the full book field. This is thoughtfully argued and written in a light-hearted style, with some neat little asides in the margins. Considering the subject matter, it's an enormously enjoyable read; I'd have like to have Mr Craven as my teacher at school.
