An ice age is a period of long-term reduction in the temperature of Earth’s surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Within a long-term ice age, individual pulses of cold climate are termed “glacial periods” (or alternatively “glacials” or “glaciations” or colloquially as “ice age”), and intermittent warm periods are called “interglacials”.Glaciologically, ice age implies the presence of extensive ice sheets in the northern and southern hemispheres.
