Ice age are properly defined as periods of "extensive ice sheets" at the poles, contrasted with "greenhouse periods" of no polar ice sheets (or glaciers). Ice ages are comprised of glacial and interglacial periods. The Last Glacial Period is... a glacial period. We're currently in an interglacial. But still an ice age, since there's ice at the poles (for now anyway).
