Ice cap climate is the world's coldest climate, and includes the coldest places on Earth. With an average temperature of −55.2 °C (−67.4 °F), Vostok, Antarctica is the coldest place in the world, and has also recorded the lowest temperature, −89.2 °C (−128.6 °F). [ 3 ]
Visualization of the ice and snow covering Earth's northern and southern polar regions Northern Hemisphere permafrost (permanently frozen ground) in purple. The polar regions, also called the frigid zones or polar zones, of Earth are Earth's polar ice caps, the regions of the planet that surround its geographical poles (the North and South Poles), lying within the polar circles.
There are two types of polar climate: ET, or tundra climate; and EF, or ice cap climate.A tundra climate is characterized by having at least one month whose average temperature is above 0 °C (32 °F), while an ice cap climate has no months averaging above 0 °C (32 °F). [2]
Polar ecology is the relationship between plants and animals in a polar environment. Polar environments are in the Arctic and Antarctic regions. Arctic regions are in the Northern Hemisphere, and it contains land and the islands that surrounds it.
Polar deserts are the regions of Earth that fall under an ice cap climate (EF under the Köppen classification). Despite rainfall totals low enough to normally classify as a desert, polar deserts are distinguished from true deserts (BWh or BWk under the Köppen classification) by low annual temperatures and evapotranspiration.
New research suggests the Greenland ice sheet is on track to cross a critical threshold that could cause runaway melting, but that it’s also possible the threshold will be crossed temporarily ...
Although the bulk of its area is covered by ice caps inhospitable to most forms of life, Greenland's terrain and waters support a wide variety of plant and animal species. The northeastern part of the island is the world's largest national park. The flora and fauna of Greenland are strongly susceptible to changes associated with climate change. [1]
The ice field is the largest in the North of the Tibetan Plateau. It is made up of several ice caps with a total area of 422.58 square kilometres (163.16 sq mi) as of 2002, and a volume of about 52 cubic kilometres (12 cu mi). The glacier snow line is 5,620 to 6,860 metres (18,440 to 22,510 ft) above sea level. [5]
