• Basic science of global warming
• Evidence from ice cores, temp readings, ocean acidity, etc
• Climate modeling and simulations
• Projected scenarios and impacts
• Actions that individuals can take to reduce impact, ranging from simple (eat less meat, adjust thermostat) to more demanding (switch to bike commute, buy electric car)
• Corporate actions (policy setting for organizations and companies, what to ask political candidates about, etc)

I am looking for something that emphasizes clarity, an engaging writing style, and a positive attitude about the possibility of averting crisis. After reading this book someone should feel that they have a good general understanding of what causes global warming, and know specific actions they can take which will have a measurable impact.

The intended audience for this book would be people who know (or suspect) that climate change is a big deal, and know they should do something about it, but don't feel personally invested in the problem or solutions.
