Global Warming

Background Info.
  • Global Warming is an increase in global average
    surface temperature due to natural or
    anthropogenic climate change.
  • The global surface area increase 1.33 degrees
    Fahrenheit during the 20th century.
  • The last 30 years has seen the highest surface
    temperatures recorded in history.
  • Glaciers are melting rapidly
  • Ocean temperatures have increased.
  • Sea levels have risen almost one foot.
  • The production and absorption of carbon dioxide
    and other greenhouse gases in not in balance.

Causes of Global Warming
  • The release of methane gas from arctic tundra and
    wetlands

4
  • Pollution is one of the biggest man made problems
    that leads to global warming.
  • Burning fossil fuels
  • Green house gas CO2
  • Mining coal and oil

5
  • Population
  • More food, more methane, more burning of fossil
    fuels
  • Manure
  • Transportation

6
Effects of Global Warming
  • Rise in sea level
  • Increase of ocean temperature
  • Decrease of snow cover

7
Impact on Animals
  • Birds laying eggs earlier
  • Plants are flowering earlier
  • Mammals are getting out of hibernation sooner

8
  • Melting of ice in Greenland and Antarctica
  • Increase in agriculture
  • Water reservoirs drying up
  • In humans, heat-related illnesses and increased
    breathing problems
  • Chance of Malaria
  • Extreme weather

9
Personal Contribution to Global Warming
  • I contribute to global warming by driving a car
    daily around campus and also driving home every
    other weekend.
  • I also am part of the United States large
    population so I contribute to using more food,
    releasing more methane, and burning more fossil
    fuels.

Solutions
  • Invest in renewable energy
  • Increase efficiency of cars
  • Plant more trees
