Transcript

  • 1. Global Warming Greatest Threat To Humanity
  • 2. What is Global Warming? • Global warming is when the earth heats up (the temperature rises). • It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. • This hurts many people, animals, and plants. Many cannot take the change, so they die.
  • 3. Global Warming - Examples June 2002 Dec 2003
  • 4. Global Warming - Examples 1914 2004
  • 5. Why it is happening?
  • 6. Main cause • Raise in normal temperature • Imbalance in greenhouse effect
  • 7. Greenhouse Gases Nitrous oxide Water Carbon dioxide Methane Sulfur hexafluoride
  • 8. The Sun’s energy passes through the car’s windshield. This energy (heat) is trapped inside the car and cannot pass back through the windshield, causing the inside of the car to warm up.
  • 9. Why it happens? Burning carbon-containing fossil fuels produces carbon dioxide
  • 10. As the temperature of oceans rise, so will the probability of more frequent and stronger hurricanes. Warmer waters and more hurricanes
  • 11. Increased probability and intensity of droughts and heat waves
  • 12. Increase in frequent volcanic eruptions due to rise in temperatures
  • 13. Forest fire increased due to hot winds
  • 14. Climate Change • Important factor affected as a result of global warming • Climate change happens when there is a change in – Sun’s output – Earth’s orbit – Drifting continents – Volcanic eruptions – Greenhouse gases
  • 15. Plastic bags and cups do not decompose so harmful to environment Paper bags and cups are eco friendly and easily decomposable Reduce the usage of cars for short distances Walk /use cycles for short distances
  • 16. What Can Be Recycled? Paper Items Paper Cardboard Envelopes Phone Books Post-it Notes Magazine Bottles and Cans Cans Plastic Bottles Glass Bottles Aluminum Foil Yogurt and Cottage Cheese containers
  • 17. Advantages of 3R’s Reduction of wastages Less pollution Efficient use of resources Increase in energy
