Other threats include global warming caused by greenhouse gases, unwise development, ozone depletion, and air pollution from outside sources.
Many scientists feel that global warming caused by greenhouse gases may eliminate arctic regions, including the tundra, forever. Some scientists believe that the over abundance of greenhous gases in the earth's atmosphere will cause global warming of the earth's climate within the next fifty years. This global rise in temperature will damage the Arctic and Antarctic more than any other biome. This is because scientists expect that the arctic tundra's winter will be shortened, melting snow cover and parts of the permafrost, which will result in the flooding of some coastal areas. Plants will die, animal migrating patterns will change, and the tundra biome as we know it will be gone. The effect global warming will have on the tundra is still uncertain. Scientists still do not know the exact result of a possible change in the world's climate on the tundra. What they do know is that with the tundra being the most fragile biome it will be the first to reflect any change in the earth.
