A mass-melting of permafrost would contribute significantly to rising sea levels.
It might also accelerate global warming by releasing greenhouse gases into the air.
Rich in organic material, the soil in the Arctic tundra will begin to decay if it thaws..

Why are there no trees in the tundra?
Tundra is found at high latitudes and at high altitudes, where the permafrost has a very thin active layer. The active layer of tundra is too thin for trees to grow, because it cannot support a tree’s roots. Tundra is sometimes called a cold desert. … In the summer, the active layer of ground thaws, and ground ice melts.
Why is the tundra cold?
First, the permafrost prevents them from taking root, then those that do manage it have shallow root systems that are not an ideal anchor to withstand the high winds. Finally, low precipitation means there is not enough water to support trees. For most of the year, the tundra biome is a cold, frozen landscape.

How is the tundra important to humans?

How do animals adapt to tundra?
Animal Adaptations in the Tundra Biome Animals need shelter and insulation in the Tundra. The animals here tend to have thicker and warmer feathers and fur. Many of them have larger bodies and shorter arms, legs and tails which helps them retain their heat better and prevent heat loss.
Why is it hard to live in the tundra?

What is unique about the tundra?
Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi, meaning treeless plain.

Do polar bears live in the tundra?
Perhaps no other wildlife symbolizes the frozen tundra regions of the Earth as do polar bears. They live on ice and snow, but that’s not a problem—these bears have some cool ways to stay warm! An outer coat of long guard hairs that stick together when wet protects a dense, thick undercoat of fur.
