The main threat to the tundra is climate change. The climate has changed by about 1.3 to 1.6 degrees in the last 20 years. This may not sound like a lot but even the slightest change in climate could ruin a whole biome. Another threat to the tundra is air pollution. Air pollution effects the tundra greatly and it is getting even worse as more people drive cars and diesel trucks.

Animals and plants that live in the tundra

# data[].attributes.body
There is animals and plants that are able to survive in the cold harsh environment because  they have certain adaptations that help them survive the cold winters. Some of these animals include the polar bear, musk ox, and arctic fox. These animals have adaptation to help the, for example the polar bear has thick white fur which helps him to stay warm and hidden from other animals. Some of the plants that live in the tundra are moss, reindeer lichen, and salix artica. these plants are able to survive in the cold environment because they grow low to the ground and they grow close together

The tundra is the coldest biome in the world with an average temperature of -30 degrees. There is a level of permafrost on the topsoil Which is why there is very little plant life and the plants that can grow there are heavily adapted to the cold harsh region. According to scientists the tundra was formed about 10,000 years ago. The tundra is covered with giant mountains, marshlands, and wetlands the freeze over in the winter.

The tundra is slightly warmer during the summer but the temperature never rises above 50 degrees. The average temperature of the tundra is -30 degrees .

The topography of the tundra is like a wet sponge which results in wetlands and marshes spread out across the biome. There is limited isolation which is another reason to why the tundra is the coldest biome.

Tundra is the coldest biome in the world. There is snow almost year around at the top of the mountains. The climate ranges from ice cap climate to subarctic as the seasons change. The temperatures never rise above 50 degrees in the summer. The tundra has a ;layer of permafrost on the soil that makes it harder for plants to grow.The tundra gets on average 6 to 10 inches of rain per year.

The latitude of the tundra is 55 to 77 north. The altitude of the tundra is 300ft to 1179ft in the mountains. This is one of the reasons to why the tundra is the coldest biome.
