to sufficiently compensate the Sun's rays for the high latitude even in summer, except for relatively brief periods in peripheral areas near the polar circles. The large amount of ice and snow also reflects and weakens of what weak sunlight the polar regions receive further, contributing to the cold.

Arctic circumpolar populations, though small, often share more in common with each other than with other populations within their national boundaries. As such, the northern polar region is diverse in human settlements and cultures. 26: 500: 205:, they receive the weakest solar radiation and are therefore generally frigid year round due to the earth's axial tilt of 23.5° not being enough to create a high maximum midday 544: 581: 1855: 1714: 2041: 1848: 1734: 1843: 1777: 346: 549: 1838: 1802: 1741: 2123: 1831: 1826: 1772: 1700: 574: 1782: 534: 529: 2138: 2128: 1797: 1787: 1729: 1707: 1690: 1685: 1604: 1807: 1636: 1502: 1416: 1366: 1751: 198: 2061: 2046: 567: 2094: 1746: 1376: 1103: 808: 259:
