Abstract
Two interesting papers on stochastic aspects of climate transitions. in particular the combined response to a periodic and a stochastic forcing, have recently been published in Tellus (Nicolis, 1982: Benzi et. al., 1982). The main conclusions from these investigations are that neither a periodic forcing nor a stochastic forcing alone can describe the temperature difference between an ice age and an interglacial period. It is, however, concluded that with both types of forcing acting a t the same time, it is possible t o get a much larger response than would be the case if one considers only the deterministic response to a suitable periodic forcing.
