Tundra Biome Characteristics
The Tundra biome is a cold biome with very little animal and plant life. It is located at 60-70 degrees N. The tundra receives about 15-25 cm of precipitation each year, mainly in the form of snow. The temperature of the Tundra ranges at about -40 degrees celsius in the winter to about 10 degrees celsius in the summer. These low temperatures, along with the permafrost under the soil, makes it hard for trees to survive in the Tundra, so the Tundra is a treeless biome. Permafrost makes it very hard for plants to grow and anchor their roots into the ground. The tundra also has a very short growing season. The animal life in the in the tundra includes polar bears, caribou and arctic foxes. All these animals have adaptations to help them survive in the Tundra, such as thick coats and blubber to keep them warm in the winter. The polar bear hibernates to avoid the harsh winters and has white fur to help it camouflage into its surroundings.
Changes in the Tundra Biome
Places Affected by Global Warming and Climate Change
A few of the places affected by the thawing of the tundra are…
Mendenhall Glacier, Alaska
Glaciers along the Canadian Rockies.
Along the edges of Greenland
And of course there are many other areas that will be seriously affected that are not listed here. But the effects of the melting ice isn’t going to only affect these places, but it could have worldwide effects . The global sea levels will increase, and this is predicted to change climates and precipitation patterns all around the world.
The tundra biome has been undergoing many changes over the years. One change is caused by one huge problem; global warming. As the heat of the earth increases, the sea ice and permafrost in the tundra is melting, which is causing major complications.Humans use so much gas and other man-made fuels, and the result of that is the greenhouse effect, which in turn contributes greatly in the process of Global Warming.
Some of the effects of Global Warming melting Tundra ice are...
Animals adapted to the cold and the sea ice, such as polar bears, will have to adapt to the warmer temperatures.
Plants adapted with short roots to collect water above the permafrost will have to adapt to an unfrozen ground without the permafrost.
When this ice melts, it becomes water, which floods the biome, dramatically affecting and hurting plants and animals.
Surrounding ecosystems and communities flood.
The rest of the world becomes warmer because of how greatly the ice and cold of the Tundra affects the rest of the earth's temperature.
