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.
The Younger Dryas was not a glacial maximum, although it was a nasty little event. There is an intriguing new theory that the melt many believe caused the event by shutting down the Gulf Stream was caused by an impact or atmospheric explosion from an asteroid or comet over Canada.
We're getting close to another interglacial maximum, which is why we've been in a warming trend. Duh.
Of course, within the larger cycle are many shorter ups and downs like the Medieval Warm Period and Little Ice Age.
