It sounds like you're saying that this occurred after a warming trend had already begun. IOWs this was a temporary fluctuation back to cold conditions in an otherwise warming climate.

It seems to me that distinctions are being blurred between the long deep cold climatic conditions that last from 60-120k years and cyclic dips in conditions during the intermediate warm periods that last from approx. 15-30k years. The former used to be called Ice Ages now every period of lower temps in the warm intermediate periods is also called and Ice Age. And then some say it's all an Ice Age as long as some ice remains on the polar caps. The term is being rendered meaningless.

My gosh, we're in an Ice Age right now.

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.
