We are still in an ice age...we’re just in one of the relatively short interglacial periods-—and, judging by the length of past interglacials, at the tail end of ours, at that.
OK, interglacials is the term then. And when there’s a temporary re-cooling during an interglacial period that is an Ice Age also. Maybe, for clarity, we could call those inter-Ice Ages to distinguish them from glacial-Ice Ages which of course aren’t overall-Ice Ages.
