  1. Global Warming in the Tundra By Rachel LeFebreand Alex Vincent

  2. Why are we here?To inform you about the terrible affects of global warming in the tundra

  3. Tundra • What?: the coldest biome in the world. On a thin layer of permafrost (permanently frozen ground) • Where?: It is at the top of the North Pole. It covers 1/5 of the Earth’s surface. (Alaska is also considered tundra) • Temperature?: Winter: -60◦F (-51◦C) Summer: 50 ◦F (10◦C)- -32 ◦ F (6 ◦ C) • Weather?: less than 10 inches of precipitation a year. • Landscape?: stark and baron.

  4. Examples: Arctic Moss Arctic Willow Bearberry Caribou Moss Diamond-leaf Willow Labrador Tea Pasque Flower Tufted Saxifrage Yellow tundra flower Plants are small and close to the ground Moss on a mount of ice

  5. Animals • Have thick fur to survive in the tundra. • Turns white in the winter • Others hibernate • EXAMPLES: • Gyrfalcon • Snowy Owl • Tundra Swan • Arctic Fox • Caribous • Musk Ox • Polar Bear

  6. Main elements: Green house gases, Greenhouse effect, radioactive forcing, CO2 in the atmosphere, The last 30 years have seen the warmest surface temperatures in recorded history Increase 1.4 degrees F from mid 1800’s- early 2000’s Scientist have found strong evidence that humans cause the warming since mid-1900’s Global Warming: The increase of average temperatures at the earth’s surface They estimate that the temperature will rise again 2-11.5 Degrees by 2100 which will damage human society and environment You will suffer from a longer, more intense allergy season than before. Research has shown that the higher carbon dioxide levels in the air, plus the warmer temperatures, force plants to bloom earlier and produce more pollen.

  7. Humans contribute to global warming by: • Releasing greenhouse gases: • Burning fossil fuels (driving you car), using energy • Carbon Dioxide emission: • -Across the entire US economy, total carbon dioxide emissions per household totaled 59 tons or 118,000 pounds in 2003. When compared to the rest of the world, US households account for over six times as much carbon dioxide emissions than the remainder of the world per year, on • average. • -Airplanes/rockets • -Cutting down trees

  8. Global warming will melt enough ice in the tundra to raise sea levels this means more droughts, extinction for many plants and animals. Animals lose their living and hunting space Arctic tundra fires may increase significantly as a result of continued global warming, warns a new study examining the relationship between historic changes in climate, vegetation, and wildfires in the tundra. Since 1970 the temperature has risen 1 degree Celsius per decade. Global warming in the tundra

  9. You release greenhouse gases when you use energy Saving energy and electricity: Turn off Lights, Appliances and Other Items Operated by Electricity When They Aren't in Use Unplug Appliances and Electric Items When Not in Use Only run the dishwasher, washer, dryer when they are full Keep Your Tires Inflated Under inflated tires wastes gasoline Carpool Buy local produce Simple ways to
