  4. 4. -The average temperature of Earth according to NASAfigures is 15°C. (59°Fahrenheit)-The hottest temperature ever recorded on our planetwas 70.7°C (159.26°Fahrenheit) in the Lut Desert ofIran in 2005.-The average global temperature on Earth hasincreased by about 0.8°Celsius (1.4°Fahrenheit) since1880-Between 1870 and 2004, global average sea levelsrose 17 cm (6.7 in)
  5. 5. Causes of Global Warming• Greenhouse effect• Pollution• Deforestation
  6. 6. The Greenhouse Effect
  7. 7. Greenhouse Effect• Greenhouse gases such as carbon dioxide, water vapor, methane, ozone and nitrous oxide hold heat in the atmosphere creating a greenhouse effect.
  8. 8. Green House Gas• Water vapor (H2O)• Carbon dioxide (CO2)• Methane (CH4)• Chlorofluorocarbons (CFC’s)
  9. 9. Pollution• Automobile• Industrial activities
  10. 10. Automobile• Burning Fuels ---> CO+Co2+CH4+Other gases• Fuel includes coal, Oil, Petrol, Diesel, Kerosence, ect..
  11. 11. Industries
  12. 12. Deforestation
  13. 13. Carbon dioxide vs. Global temperature graph
  14. 14. Effects ofglobal warming
  15. 15. Melting polar ice caps will raise ocean levels;
  16. 16. Heat waves and droughts will be morefrequent.
  17. 17. Forest fire increased due to hot winds
  18. 18. The Spread of DiseaseUp to 300,000 people a year dying – partly from the spread of tropical diseases.
  19. 19. More than a million species worldwide could be extinct by 2050.
  20. 20. Increase in frequent volcanic eruptions due to rise in temperatures
  21. 21. WHAT CAN WE DO?
  22. 22. Energy ConservationUse Alternate sources of energy• Solar Wind Hydroelectric Geothermal
  23. 23. REUSE•Paper•Covers and boxes•Plastic bags
  24. 24. Plastic bags and cups do Paper bags and cupsnot decompose so are eco friendly andharmful to environment easily decomposable Reduce the usage Walk /use cycles for of cars for short short distances distances
  25. 25. What Can Be Recycled? Paper ItemsPaper Cardboard Envelopes Phone Books Magazine Bottles and Cans Cans Glass Bottles Aluminum Foil
  26. 26. 18% 11% 9% 5% 3% 11% 4% 39%Fridge TV Fan Computer AC Heater/Geyser Appliances Light
  27. 27. Conserve electricity! DO NOT leave appliances on standby Turn off the lights when you leave.
  28. 28. Turn to compact florescent light which saves more than 80% of energy
