Life at the poles is a life of contrasts; full of times of peril and periods of icy calm. Presented by BBC Earth Productions.
An ice cap climate is a polar climate where the temperature never or almost never exceeds 0 °C (32 °F). The climate covers areas in or near the polar regions, such as Antarctica and Greenland, as well as the highest mountaintops.
Such areas are covered by a permanent layer of ice and have no vegetation, but they may have animal life, that usually feeds from the oceans.
There is very little surface life in ice cap climates. Vegetation cannot grow on ice, and is non-existent. However, the fringes of ice caps do have significant animal life.
There is a hypothesis that around 650 million years ago, the entire planet was frozen, called Snowball Earth. Essentially the entire planet had an ice cap climate.
