noun ice ages · Ice Age

  1. A period of long-term reduction in the temperature of Earth's surface and atmosphere, resulting in the presence of major polar ice sheets that reach the ocean and calve icebergs.

  2. colloquial Any of several glacial periods (within a scientific ice age) marked by episodes of extensive glaciation alternating with episodes of relative warmth (interglacial). The cause of ice ages, Köppen decided, is to be found in cool summers, not brutal winters.
