Probability of climatic change. Identification of key questions

Addressing the question what the probability is of an anthropogenically induced change in the climate, leads to a number of other, underlying questions. These questions, which deal with the characteristics of climate, of climatic change, and of probabilistic statements on climatic change, should be addressed first. The long-term objective of the underlying study, i.e. a quantitative assessment of the risks and opportunities of the predicted climatic change, sets the context against which of those questions should be answered. In addition, this context induces extra questions, i.e. about the characteristics of risk
