An ice age is a long period of reduction in the temperature of the 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. An ice age is a period of time in which the earth's temperature is too low for the winter ice to melt back fully during summer ice ages, of which there have been many, are characterised by massive glaciers covering the subpolar and mountainous parts of the world, and by a lowering of sea levels.
