Likelihood, (see Table 1 from the IPCC report referenced), provides calibrated language for describing quantified uncertainty. It can be used to express a probabilistic estimate of the occurrence of a single event or of an outcome (e.g., a climate parameter, observed trend, or projected change lying in a given range). Likelihood may be based on statistical or modelling analyses, elicitation of expert views, or other quantitative analyses. The categories defined in Table 1 (see report) can be considered to have “fuzzy” boundaries. A statement that an outcome is “likely” means that the probability of this outcome can range from ≥66% (fuzzy boundaries implied) to 100% probability. May also be determined according to expert judgment and/or plausible argument.
