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

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.
