 Some of these critics of probabilistic approaches advocate a very different interpretation of results from today’s ensemble projection studies, according to which the projections indicate changes that are (merely) plausible or possible in light of current understanding. Stainforth et al. (2007), for example, suggest that the range of projections produced using state-of-the-art climate models constitutes a “non-discountable envelope” of future changes, a set of possible changes that should not be disregarded; this does not imply that changes outside the envelope are discountable. Likewise, Katzav (2014) argues that climate change projections can often be interpreted as indicating real possibilities:
