Regions with a polar climate are characterized by a lack of warm summers (specifically, no month having an average temperature of 10 °C (50 °F) or higher). Regions with polar climate cover over 20% of the Earth. The sun shines 24 hours in the summer, and barely ever shines at all in the winter (see midnight sun and polar night). Polar climate results in treeless tundra, glaciers, or a permanent or semi-permanent layer of ice.
