	Polar night - Wikipedia, the free encyclopedia
		In regions inside the polar circles, the length of the time when the sun is below the horizon varies from 20 hours at the Arctic Circle and Antarctic Circle to 179 days at the Poles.
		This is because polar night is the period during which no twilight occurs; but there are various kinds of twilight.
		The nautical polar night is limited to latitudes above 78° 33′, which is exactly 12 degrees within the polar circle, or eleven and a half degrees from the pole.

	Polar Bear
		Polar bears have fur that is made up of "hollow guard hairs." Sometimes when polar bears live in zoos that are in a warmer climate, they can have algae growing inside the hollow guard hairs of their fur.
		Polar bears are usually solitary except for female-cub groups, during mating season, and at abundant food sources.
		Polar bears find a seal air hole and sneak up on it slowly and sit there until a seal comes up to breathe and then they scoop him right out of the hole.

		Polar bears in the Hudson Bay area are among the most concentrated along any shore, with around 1200 bears estimated in the western Hudson Bay population.
		Although the likelihood of reaction was not affected by the minimum number of days bears were in the tourist area, bears were much more likely to react to the first vehicle approach than subsequent approaches, implying that habituation occurs within a single day in the tourist area.
		Polar bears at the Brookfield Zoo have reproduced many times, but the survival rate of the cubs was very low--until 1972, when the zoo introduced new maternal dens.

	CalendarHome.com - Season - Calendar Encyclopedia
		In temperate and polar regions generally four seasons are recognised: spring, summer, autumn (fall), and winter.
		In some tropical and subtropical regions it is more common to speak of the rainy (or wet, or monsoon) season versus the dry season, as the amount of precipitation may vary more dramatically than the average temperature.
		With the solstices (peaks) are used as the middle of each season, as is in Jieqi and East Asian countries, the longest day of the year occurs in the middle of summer, and conversely the shortest day of the year in the middle of winter.

	Polar Day and Night: A Primer
		The long cycle of day and night is caused by the tilt of the earth's axis as the earth orbits the sun.
		People of polar regions have adapted themselves to these conditions as well as possible, but the "big-eye," or sleeplessness, is a frequent problem during arctic summers when the sun streams into bedrooms all night long.
		Depending on the latitude, polar day begins anywhere from mid-March through mid-May, while polar night begins anywhere from late September through late November.

		In stark contrast to last year’s Polar Bear Day, which had to be cancelled due to the lake’s closure from storm runoff contamination, this year’s Polar Bear Day took place under idyllic conditions — blue skies, 78-degree temperatures and 54-degree water.
		Fortunately, earlier threats of lake contamination from last week’s rainfall were dismissed and 40 participants showed up for the day’s event, hosted by the Ski Club.
		The roaring bonfire in the foreground provided a gathering place for participants and spectators to enjoy the summer-like day and dry off from the winter-like water temperatures.
