Tundra Animals Lennox Island residents may be the first climate change refugees in Canada As sea level rise threatens homes, indigenous people living on tiny Lennox Island face the possibility of becoming Canada‘s first climate change refugees. 450 Mi’kmaq people reside there, and have tried to protect their coasts with rock. Ultimately, however, loss of land will likely force them to relocate. Lennox Island, which is right by Prince Edward Island, is losing land as sea levels creep upwards. In 1880, the island was around 1,500 acres big. Land surveys reveal the tiny island has now lost nearly 300 acres of that land. *Tundra encroachment by tundra due to climate change In Alaska, trees growing at the very edge of their northern range may be influenced by warming climate. Will they eventually take over the tundra beyond? Scientists from Columbia University’s Lamont-Doherty Earth Observatory and other institutions are studying how these remote ecosystems may change. Here’s a video from scientists at the northern edge of the treeline.
Earth Floor: Biomes Arctic Tundra Arctic tundra is found across northern Alaska, Canada, and Siberia. This biome has long cold winters and short cool summers. The Arctic tundra has low precipitation (less than 10 inches per year) and dry winds. Earth Floor: Biomes Arctic Tundra: Animals Not many kinds of animals live year-round in the Arctic tundra. Most birds and mammals only use the tundra as a summer home. Mammals that do live year-round in the tundra include the muskox, Arctic wolf, and brown bear; and each has its own way of adapting to the extreme climatic conditions. Animals need to find ways to stay warm and to provide nourishment for themselves in order to survive the long, cold, winter months. Animal adaptations Migration and hibernation are examples of behavioral adaptations used by animals in the Arctic tundra. The fact that many animals do not live year-round in the tundra means they leave or migrate for a length of time to warmer climates.
