Arctic Tundra
Referred as “treeless plain”
Earth's coldest biome!
Earth's youngest biome! (formed 10,000 years ago)
Located in the Northern Hemisphere (Alaska, Canada, and Siberia)
Known for its cold, desert like conditions
Average Temperature (Winter): -34° C (-30° F)
Average Temperature (Summer): 3-12° C (37-54° F)
Arctic Tundra
Wide variety of plants (1,700 kinds of plants)
Short growing season (50 – 60 Days)
Carbon Sink (Stored in permafrost)
Animals adapted to long winters
Animals breed and raise young quickly in the summer
Many animals hibernate during the winter, others alternative is to migrate south in the winter
Constant immigration and emigration

Global Warming: Adding more Carbon to the atmosphere means more heat radiation is captured by the atmosphere and radiated back to
Earth
Human Contribution
Humans burn fossil fuels, thus carbon dioxide is released into the atmosphere where it traps heat. Adding greenhouse gasses into the atmosphere witch affect the Arctic
Greenhouse gases and aerosols affect climate by altering incoming solar radiation and out going thermal radiation that are part of Earth’s energy
