An ice age is a long period of reduction in the temperature of the earths surface and atmosphere resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Monthly sea ice data show trends of increasing sea ice extent that are slightly above the mean year to year variability over the satellite record 1979 to present.
