what is the coldest temperature ever recorded in alaska
Climate of Alaska The highest and lowest recorded temperatures in Alaska are both in the Interior. The highest is 100 °F (37.8 °C) in Fort Yukon on June 27, 1915.[5][6][7][8] The lowest Alaska temperature is −80 °F (−62.2 °C) in Prospect Creek on January 23, 1971,[5][6] 1 °F (0.6 °C) above the lowest temperature recorded in continental North America (in Snag, Yukon, Canada).[9] Alaska also holds the extreme US record low temperatures for every month except July and August.
Alaska Alaska (/əˈlæskə/ ( listen)) (Aleut: Alax̂sxax̂) (Inupiaq: Alaskaq) is a U.S. state located in the northwest extremity of North America. The Canadian administrative divisions of British Columbia and Yukon border the state to the east, its most extreme western part is Attu Island, and it has a maritime border with Russia to the west across the Bering Strait. To the north are the Chukchi and Beaufort seas–the southern parts of the Arctic Ocean. The Pacific Ocean lies to the south and southwest. It is the largest state in the United States by area and the seventh largest subnational division in the world. In addition, it is the 3rd least populous and the most sparsely populated of the 50 United States; nevertheless, it is by far the most populous territory located mostly north of the 60th parallel in North America, its population (the total estimated at 738,432 by the U.S. Census Bureau in 2015[5]) more than quadrupling the combined populations of Northern Canada and Greenland. Approximately half of Alaska's residents live within the Anchorage metropolitan area. Alaska's economy is dominated by the fishing, natural gas, and oil industries, resources which it has in abundance. Military bases and tourism are also a significant part of the economy.

Antarctica Antarctica is the coldest of Earth's continents. It used to be ice-free until about 34 million years ago, when it became covered with ice.[63] The coldest natural air temperature ever recorded on Earth was −89.2 °C (−128.6 °F) at the Soviet (now Russian) Vostok Station in Antarctica on 21 July 1983.[64] For comparison, this is 10.7 °C (20 °F) colder than subliming dry ice at one atmosphere of partial pressure, but since CO2 only makes up 0.039% of air, temperatures of less than −140 °C (−220 °F)[65] would be needed to produce dry ice snow in Antarctica. A lower air temperature of −94.7 °C (−138.5 °F) was recorded in 2010 by satellite—however, it may be influenced by ground temperatures and was not recorded at a height of 7 feet above the surface as required for the official air temperature records.[66] Antarctica is a frozen desert with little precipitation; the South Pole itself receives less than 10 cm (4 in) per year, on average. Temperatures reach a minimum of between −80 °C (−112 °F) and −89.2 °C (−128.6 °F) in the interior in winter and reach a maximum of between 5 °C (41 °F) and 15 °C (59 °F) near the coast in summer. Sunburn is often a health issue as the snow surface reflects almost all of the ultraviolet light falling on it. Given the latitude, long periods of constant darkness or constant sunlight create climates unfamiliar to human beings in much of the rest of the world.[67]
