WorldWatch-org may be the top global environmental watchdog, and this another great annual report. It's focused entirely on climate change this time (except for the fascinating annual timeline at the beginning). If you're not sure if you want it, go to their website and look at one of its 6 chapters (in pdf):
Chp 1: The Perfect Storm. The big picture view of climate policy history and policy considerations.
Chp 2: A Safe Landing for the Climate. How to avoid climate tipping points. A little fuzzy on the science here, but basically sound. (They think cooling won't help once a tipping point is passed. It would. But a tipping point is when the warming is self-sustaining and cooling becomes impossible.)
Chp 3: Farming and Land Use to Cool the Planet . Fairly detailed agricultural ideas.
Chp 4: An Enduring Energy Future. Good overview of renewables. Also a bit about carbon pricing.
Chp 5: Building Resilience. How to reduce the vulnerability of individuals, communities, and countries to the threats of climate change.
Chp 6: Sealing the Deal to Save the Climate. "Humanity needs to cap and then start shrinking global emissions." Describes a complex and rather vague system for Greenhouse Development Rights.

Like most global warming books, this one is weakest on what to do about it. General principles don't get the job done. Plan B 3.0: Mobilizing to Save Civilization (Substantially Revised) is by a splinter group that is a bit smarter on policy, but it still does not say much. The one recent and accessible book dedicated to explaining real-world policy is Carbonomics: How to Fix the Climate and Charge It to OPEC. It advocates James Hansen's 100%-refunded carbon tax, but it also covers cap-and-trade, Kyoto II, and a lot of other policies being discussed by Congress and the World.
