Tundras in the future...or not.
Climate change in the Arctic is a growing concern for natural resource conservation and management as a result of accelerated warming and associated shifts in the distribution and abundance of northern species. Large swaths of the Arctic tundra will be warm enough to support lush vegetation and trees by 2050. Polar and sub-polar climate types will decline and will be replaced by more temperate climates. Tundras will turn from being dry and cold into more suitable environments capable of supporting more diverse plants and animals. However, this means the extinction of native species of this particular tundra. Tundra coverage would shrink by 33 to 44 percent by the end of the century, while temperate climate types that support coniferous forests and needle-leaf trees would push northward into the breach.
