Technical Abstract: The science and policy interface is often an uncomfortable, unlikely exchange that takes time to mature and develop, from both a process and an interpersonal perspective. Scientists, by temperament and training, are whetted to a logical, orderly method of discovering the laws of nature that order the world and our surroundings, and to presenting those discoveries in peer-reviewed scientific journals. Often it the media that play the inte4mediary role of interpreting to the public ¿ and to policy makers among them ¿ scientific findings, and the implications of those findings to people and to good policy. Frequently, however, relevant scientific details are simplified, misinterpreted, or even omitted in the interpretation and presentation by the media. Such omissions or explanation often occur as part of the process of making news relevant. Most scientists have neither the training nor the opportunity to interact on the arena where policies are crafted and laws debated and passed, but it is imperative that the interface exist and be nurtured, particularly where problems are complex and the outcome of policies an legislation imperative. Climate change and soil carbon sequestration are such areas and are addressed in this book.
