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 ]
For animals, there has been a decrease in the number of polar bears in the Hudson Bay area. [36] Since 1981, the polar bear population has been declining. This is because global warming causes the ice to break up faster so the polar bears are going to the coasts when there are poor conditions. [36]
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] In a tundra climate, even coniferous trees cannot grow, but other specialized plants such as the arctic poppy can grow.
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.
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.
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 research suggests the critical threshold for the Greenland ice sheet is between 1.7 and 2.3 degrees C of global warming. Bochow said humanity would have 100 years — perhaps more — to cool ...
In glaciology, an ice cap is a mass of ice that covers less than 50,000 km 2 (19,000 sq mi) of land area (usually covering a highland area). Larger ice masses covering more than 50,000 km 2 (19,000 sq mi) are termed ice sheets .
