As governments around the globe begin to wake up to the far reaching effects of changes in climate, the search for available options and instruments for addressing the issue becomes increasingly vital. This authoritative, step-by-step guide to the assessment of the impacts from, and potential adaptations to, changes of climate is based on the approach developed by the authors and other scientists for the Intergovernmental Panel on Climate Change (IPCC). This approach has been widely adopted as 'best practice' by experienced researchers but has not, until now, been available in an accessible form. This illuminating account of the methods used by the IPCC scientists will be essential for all those involved in the study of climate impacts and adaptations, or designing and implementing policies for dealing with them. Written in non-technical language, this state-of-the-art guide is ideal for all people interested in the far-reaching implications of climate change and the greenhouse effect. The book contains numerous illustrations, including several worked examples, clearly presented in boxes and diagrams.
