Created with Fabric.js 1.4.5 Tundra is the coldest and driest biome in the world.The winters are long, but they receive very littlerainfall. The winter temperature can reach as lowas -45 degrees Celsius. Summers are short and the daylight days are 24 hours long. Summertemperatures rarely exceed 10 degrees Celsius. The green shaded area indicates where the arctic tundra is. There are a very small number of organisms that live in the arctic tundra Many lichens, moss and shrubs flourish in the harsh tundra. The way that the plants adapt to the permafrost soil is by being short and tightly grouped together to resist the strong wind and to stay protected. There are actually animals that live in this biome. You can find: lemmings, arctic hares, mountain goats, migratory birds and of course polar bears. Climate change has by far the biggest affect on the arctic tundra biome. The warming of this biome is twice as fast as the globalrate. The ice is melting, causing sea levels to soar. Warmer tundra means warmer temperatures in Europe and other surrounding countries. Acid rain is also affecting the sea life that occupy the oceans of the arctic. Another way that humans have affected the tundra environment is through the many untouched oil reserves. The arctic has become a target for oil companies. Rubbish and other wastehas also left some parts of the arctic polluted. ARCTIC TUNDRA The Tundra biome is quite big. It covers about one fifth of the land on the earth. It is located in the arctic circle and around the north pole. You can also find tundra in Antarctica, Alaska, Canada, Siberia and other freezing places like that. By Anita Loschiavo The arctic tundra is important because it plays a major role in regulating the temperature of the whole earth. As warm air rises from the tropical parts of the planet, it reaches the tundra, which cools it making it sink back to the equator. This causes weather and air currents. Without this system the climate of the entire world would change drastically. Biomes would be different and so would all of the vegetation and animals. Areas that could once support life might not be ableto anymore. It is also home to many species of animals. If they were to becomeextinct, it would cause major problems in the food chain.
