The tundra is one of earth’s biomes that is characterized as being cold and dry almost year round. The summers in the tundra are so short that the soil doesn’t get a chance to fully unthaw. This perpetually frozen layer of soil is called permafrost. Because of the harsh weather in the tundra there are not many trees and plant life is extremely minimal except for during the short summer months. Tundras are found in far northern regions of the earth. The tundra is home to animals such as arctic fox, caribou, wolves, bears, several species of birds and some plant species. The tundra, because it doesn’t fully thaw, stores large amounts of carbon. Because of global warming the carbon stored in the tundra is slowly being released into the atmosphere adding to the green house effect and therefore global warming.
