Global warming and its effects

  1. 1. Global Warming Presentation by: PITHADIA SHRUTI
  2. 2. What is Global Warming?  The changes in the surface air temperature, referred to as global temperature, brought about by the enhanced green house effect, which is induced by emissions of green house gases in the air.
  3. 3. It should NOT be confused with climate change
  4. 4. Difference GLOBAL WARMING is the increase of the Earth’s average surface temperature due to a build-up of greenhouse gases in the atmosphere. CLIMATE CHANGE is a broader term that refers to long-term changes in climate, including average temperature and precipitation.
  5. 5. How Global Warming Works Carbon Dioxide (CO2) Greenhouse gases Fossil fuels (coal, oil, natural gas)
  6. 6. Why Global Warming?
  7. 7. Some of the activities of man also produce greenhouse gases. The balance of the greenhouse gases changes and this has effects on the whole of the planet.
  8. 8. Effects of Global Warming     Increased sea level Changes in water supply Rising temperature Damage to habitats
  9. 9. Warmer waters and more hurricanes
  10. 10. Increased probability and intensity of droughts and heat waves
  11. 11. At some places, it
  12. 12. At others……
  13. 13. SOMEWHERE it’s too…….
  14. 14. HOT
  15. 15. WHEREAS At others too…..
  16. 16. COLD
  17. 17. WHO Is THE CULPRIT????
  18. 18. Global Atmospheric Concentration of CO2
  19. 19. It’s NOT too LATE ACT NOW!!!!
  20. 20. What should be done to reduce our emissions?
  21. 21. Dress lightly when it’s hot instead of turning up the air conditioning.
  22. 22. Spread awareness
  23. 23. Be Bulb Smart—Use CFLs Compact Fluorescent Incandescent 5 0 0 l b •1,430 lbs. CO •$30 saved s . 2 pollution avoided
  24. 24. Plant trees.
