"The failure of the Copenhagen climate conference in December 2009 revealed major flaws in the way the world's policy makers have attempted to prevent dangerous levels of increases in global temperatures. The expert authors in this specially commissioned collection focus on the likely costs and benefits of a very wide range of policy options, including geoengineering; mitigation of CO₂, CH₄, and "black carbon"; expanding forest Carbon Sequestration; R&D of low-carbon energy; and encouraging green technology transfer. For each policy, the authors outline all of the costs, benefits and likely outcomes, in fully referenced, clearly presented chapters accompanied by shorter, critical alternative perspective papers."-P.
