Drawdown by Paul Hawken

For the first time ever an international coalition of leading researchers, scientists and policymakers has come together to offer a set of realistic and practical solutions to climate change.

If deployed collectively on a global scale over the next thirty years, they could not just slow the earth's warming, but reach drawdown: the point when greenhouse gases in the atmosphere peak and begin to decline. 

So what are we waiting for?
