Just for clarification, we’re still in an ice age. We have been for roughly 3 million years. We’re currently in an interglacial period that’s about over.
For most of it’s history, the earth had no glaciers or ice covered poles. Temperatures were 6 to 9 degrees F higher on average.

Yes, we are still in the Pliocene-Quaternary Ice Age. The major ice ages took up
300--Huronian Ice Age
50--Sturtian Ice Age (period of Snowball Earth)
15--Marinoan Ice Age 40--Andean-Saharan Ice Age
100--Karoo Ice Age
2.6--Pliocene-Quaternary Ice Age
____
507.6 million out of about 4,500 million years
Given the length of the rest, we've still got quite a long way to go before we're out of the current one. And given the average length of the interglacials of the current ice age, we're right on the edge of the next glacial period.
