Such areas include Antarctica, Greenland, and some parts of Europe. Also, because Earth's axis is tilted with respect to the plane in which it circles the sun, for about half the year the poles receive weak 24-hour sunlight, and for the rest of the year are in constant darkness.

Pollution of the waters in polar regions is another threat to the lands and animals that live there. The typical temperature of polar nights is even lower than the 50 °F average, and some polar climate regions are even colder, with average temperatures of less than 0 °F.
Alpine climate can mimic either tundra or ice cap climate. Antarctica has the lowest naturally occurring temperature ever recorded: −89.2 °C (−128.6 °F) at Vostok Station. Average January temperatures range from about −40 to 0 °C (−40 to 32 °F), and winter temperatures can drop below −50 °C (−58 °F) over large parts of the Arctic. The temperature rarely rises above the freezing point and it often sits far below zero, way colder than the winters you might be used to! Additionally, since the ice sheets never melt, the ground is perennially dry. You might also think of freezing temperatures, snow up to your ears, and so much ice that you need ice skates to get around! Many high altitude locations on Earth have a climate where no month has an average temperature of 10 °C (50 °F) or higher, but as this is due to elevation, this climate is referred to as Alpine climate. The polar climate regions are characterized by a lack of warm summers. Polar bears have a diet that consists mostly of seals because they need to eat large amounts of fat to survive. Average July temperatures range from about −10 to 10 °C (14 to 50 °F), with some land areas occasionally exceeding 30 °C (86 °F) in summer.
The polar climate is full of wildlife, extreme weather, and unique landscapes. Polar climates also tends to be extremely dry since the descending cold air does not have a significant amount of moisture. A polar climate consists of cool summers and very cold winters, which results in treeless tundra, glaciers, or a permanent or semi-permanent layer of ice. Think of it as ice in your glass of water melting.
Marine life can get tangled in garbage that is floating in the water, and polar bears can be affected when they eat fish that have come into contact with polluted water. 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 above 0 °C (32 °F).
