2.  Albedo – surface reflectivity of the suns radiation.  Not enough sunlight is being reflected but is being absorbed, increasing sea level temperatures  http://www.youtube.com/watch?v=fJ999LIWvJk http://www.youtube.com/watch?v=fJ999LIWvJk  Regional climate change  Human Activity  Global Warming  Greenhouse gases buildup in the atmosphere- carbon dioxide and methane

3.  Polar bears – hunt and raise cubs on sea ice  Walrus – feeding grounds are on sea ice  Harped, Spotted, Ringed seals –use sea ice as resting area, birth/raising, and protection  Penguins/Seabirds – breed, raise young, feeding grounds on sea ice  Phytoplankton – sparks blooms due to bacterial growth and temperature change

4.  Pollution brought in by precipitation bring disease to animals  Low maturity rate  Low reproductive rate  Feeding grounds being destroyed  Death

5. IIce is crucial for food, resting, and reproduction thus if shrinking continues mortality increases IIf extinct this keystone species in the arctic region would likely have impacts on other species in the habitat Effect: The seals are a main food source for the polar bears and if they are unable to hunt for them on the ice they will die and then the seals would overpopulate and so they would lessen the fish population.

6. LLess food = no fat preservatives = less reproductive success HHaving to swim longer distances to hunt for food exhausts the polar bear which can lead to drowning LLow chance for survival rates for cubs if there is no shelter or food NNo areas to rest may result in death due to exhaustion and starvation

7.  Decrease salinity of sea water adding freshwater = change in water currents  Release of methane and carbon dioxide in atmosphere due to permafrost melting  Climate change/weather change  Rising ocean temperature  Biodiversity

8. RRising ocean levels-devastating effects on coastal towns, cities, and ecosystems IIce sheets and glaciers over Greenland and Antarctica are not floating so ocean levels rise as it melts  Melting of floating arctic ices do not rise ocean levels because the weight is equal to the displaced water. OOcean also expands as it gets warmer hhttp://www.youtube.com/watch?v=4XU4jcpyDC8

9.  Sparks Plankton blooms due to bacterial growth and increased water temperature  Beneficial to plankton feeding animals

10. NNot burning so much fossil fuel AAlternate sources of energy – wind, solar, biofuels, and etc.
