Climate Tundra Biome - Tundra Climate (E) | The Cold Climate | The Köppen Climate Classification System | Resources In: The Cold Climate Updated 29 Jan 2013 Did you know that the Arctic Tundra is the world's youngest biome? It was formed 10,000 years ago. Tundra comes from the Finnish word "tunturia", which means a barren land. The main seasons are winter and summer. The Arctic tundra is also a windy place and winds can blow between 30 to 60 miles (48 to 97 kilometers) per hour. The tundra is basically like a desert when it comes to precipitation. There is barely any vegetation in the tundra, only about 1,700 different species, which isn't very much. Surprisingly there are animals in the tundra. The tundra is one of Earth's three major carbon dioxide sinks. The tundra is a very fragile environment. Pollution from mining and drilling for oil has polluted the air, lakes and rivers. The tundra is not a cold and useless wasteland. by Whitney S. 2002 Köppen Classification & Biomes | Cold Climate | Dry Climate | Temperate Climate | Tropical Climate
Fact Interesting Facts The tundra biome Online exhibits : The world's biomes The tundra biome Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi, meaning treeless plain. Characteristics of tundra include: Extremely cold climate Low biotic diversity Simple vegetation structure Limitation of drainage Short season of growth and reproduction Energy and nutrients in the form of dead organic material Large population oscillations Tundra is separated into two types: Arctic tundra Arctic tundra is located in the northern hemisphere, encircling the north pole and extending south to the coniferous forests of the taiga. All of the plants are adapted to sweeping winds and disturbances of the soil. Animals are adapted to handle long, cold winters and to breed and raise young quickly in the summer. Alpine tundra Alpine tundra is located on mountains throughout the world at high altitude where trees cannot grow. Animals living in the alpine tundra are also well adapted:
Fact Tundra Facts undefined The Tundra Biome: Facts The Tundra Biome is one of the most unique Biomes in the world. Because of its northern location there are many substantial Facts about the Tundra Temperature: The Tundra has extremely cold temperatures. Land: The Tundra is permanently covered by a layer of frozen soil, or permafrost. Day Length: Because of the Tundra's northern position, during the winter, sometimes only a few hours or less of sunlight occur. Types of Tundra: There are two different types of Tundra, Polar Tundra and Arctic Tundra. Precipitation: The average yearly precipitation in the Tundra is usually less than 15 inches.
Lennox Island residents may be the first climate change refugees in Canada | Inhabitat - Green Design, Innovation, Architecture, Green Building As sea level rise threatens homes, indigenous people living on tiny Lennox Island face the possibility of becoming Canada‘s first climate change refugees. 450 Mi’kmaq people reside there, and have tried to protect their coasts with rock. Ultimately, however, loss of land will likely force them to relocate. Lennox Island, which is right by Prince Edward Island, is losing land as sea levels creep upwards. In 1880, the island was around 1,500 acres big. Land surveys reveal the tiny island has now lost nearly 300 acres of that land.

Indigenous and Northern Affairs Canada will pay for erosion surveys but hasn’t yet offered money to help the residents relocate or even place boulders on the island shores. Via VICE
Tundra picture The Tundra's Climate *Tundra encroachment by tundra due to climate change In Alaska, trees growing at the very edge of their northern range may be influenced by warming climate. Will they eventually take over the tundra beyond? Scientists from Columbia University’s Lamont-Doherty Earth Observatory and other institutions are studying how these remote ecosystems may change. Here’s a video from scientists at the northern edge of the treeline. Tundra Picture The animals Earth Floor: Biomes Arctic Tundra Arctic tundra is found across northern Alaska, Canada, and Siberia. This biome has long cold winters and short cool summers. The Arctic tundra has low precipitation (less than 10 inches per year) and dry winds. One unique characteristic of the Arctic tundra is permafrost--ground that is permanently frozen. Curiously, during the summer Arctic tundra is characterized by lots of surface water. Back | Next
