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.

“Culture is the name for what people are interested in, their thoughts, their models, the books they read and the speeches they hear, their table-talk, gossip, controversies, historical sense and scientific training, the values they appreciate, the quality of life they admire. All communities have a culture. It is the climate of their civilization.”
—Walter Lippmann (1889–1974)
