Arctic Tundra As children, we dream of the North Pole as a magical place ware happiness fills the air. The North Pole along with Alaska, Northern Canada, Northern Scandinavia, Northern Siberia, Russia and edges of Greenland are all in the Arctic Tundra. The tundra’s latitudes are 55 degrees to 75 degrees N. This covers over three million square miles and encapsulates one fifth of the Earths land mass. This biome is the coldest of all of them, yet it’s also one of the driest. The Tundra rarely gets above -18 degrees during the harsh winter.

In the spring the top layer of the permafrost softens and allows some plants to grow and repopulate. Nonetheless these plants become passive when winter comes.
