  1. Global Warming By: Flavia Arthur MYP3

  2. What is Global Warming? • The temperate in the atmosphere increases. • It happens when greenhouse gasses trap heat and light from the sun.

  3. How does it affect the planet?

  4. What are the Causes? • Carbon dioxide:- Fossil Fuel- Deforestation- Carbon Sink • Methane:- Cattle and Rice Paddies- The Artic Tundra • Nitrogen Oxides: - Farming • Other Gasses

  5. Carbon Dioxide • Carbon Dioxide is one of the main causes • Fossil fuels:- burning- cars- airplanes- coal plants • Deforestation:- All living plants store carbon-Carbon dioxide released every time a plant dies

  6. Carbon Dioxide • Carbon Sink:- Stores carbon- Artic tundra- sinks fail, carbon released into atmosphere • Oceans:- Giant carbon sinks- stores 50 times more carbon than the atmosphere

  7. Methane • 100 times more powerful than carbon dioxide. • Created when:- Bacteria breaks down natural matter- Matter trapped under water - rice paddies- Intestines of herbivorous animals - cows - sheep - goats- Land fills

  8. Methane • Clathrates- frozen pieces of ice and methane at bottom of ocean • As water heats ice melts releasing methane

  9. Nitrogen Oxide • Traps heat 300 times more the carbon dioxide. • Get released every time a plant is fertilized

  10. Other gasses • Chlorofluorocarbons and hydrochlorofluorocarbons • Used in refrigeration

  11. How do you prevent Global Warming? • Reuse, reduce, recycle • Use less heating and air-conditioning • Buy energy efficient products • Plant a tree • Turn off lights when not in use
