About the book: This book addresses the following questions: * What is the nature of avoided impact benefits from policies that limit global warming and how do these vary by sector or region? * Can these benefits be quantified and monetised reliably? * How do adaptation and mitigation policies interact? * What is the nature of ancillary or nearer term, local benefits of mitigation policies and how do they compare to other types of benefits? * How does the risk of abrupt climate change affect these benefits? * How might integrated assessment models help us to assess climate policy cost and benefit trade-offs? * Are there new ways to work with risk-based approaches to look at mitigation policy alternatives?
