  1. 1. Group Member :<br /> Mr. Pravin Chavan.<br /> Mr. Ramkrishna Lipare.<br />Guided By : Mr. K. K. Awale. Sir.<br />
  2. 2. What is Global Warming<br />Why is this warming bad?!<br />Impacts<br />What We Can Do<br />
  3. 3. What is Global Warming?<br /><ul><li>Global Warming is the theory that we as humans are increasing greenhouse gases (the layer of gases that catches the sun’s rays and heats the earth) through industrialization causing more gases and increasing the amount of sunlight that gets caught and heats the Earth.</li></li></ul><li>General Viewpoint<br /><ul><li>The general viewpoint is that global warming and pollution from CO2 emissions are adding to greenhouse gases so significantly that the Earth is warming up and will continue to warm.</li></li></ul><li>Why is this warming bad?!<br /><ul><li>We believe that this increase in temperature will eventually cause the melting of the ice caps. This melting could increase the oceans height by up to 2 feet in only one century! This would mean many heavily populated costal cities would flood causing millions maybe billions of dollars and damage and the potential loss of life in these cities.</li></li></ul><li>Other Effects from Global Warming<br /><ul><li>There are also other effects to global warming such as natural disasters have been increasing, disease have been spreading more rapidly, and animals have been found migrating towards the poles due to the increase in heat. </li></li></ul><li>USFWS photo<br />USFWS photo courtesy Ed Berg<br />Effects on Wetlands and Forests<br />Over the last 5 decades, in areas of the Kenai NWR:<br /><ul><li>Open areas decreased by 34%
  4. 4. Wet areas decreased by </li></ul> 88%<br /><ul><li>Water and lakes decreased by 14%</li></li></ul><li>Disappearing & Shrinking Ponds<br />Disappearance of Ponds since 1950’s<br />% Decrease in Number of Ponds<br />% Decrease in Area of Ponds<br />Study Area <br />Copper River Basin<br />Minto Flats SGR<br />Innoko Flats NWR<br />Yukon Flats NWR<br />54 %<br />36 %<br />30 %<br />10 %<br />28 %<br />25 %<br />31 %<br />18 %<br />Based on Inventory of 10,000 closed-basin ponds<br />
  5. 5. “The surface ocean currently absorbs about one-fourth of the CO2 emitted to the atmosphere from human activities.”<br />CO2 + H20 HCO3- + H+<br />CO2<br />CO2<br />Ocean Acidification<br /> Monaco Declaration 2008<br />Remains in the atmosphere (greenhouse gas)<br />Dissolves in sea water<br />(ACID)<br />Water becomes more acidic.<br />
  6. 6. Real Facts <br /><ul><li>The number of category 4 and 5 hurricanes have almost doubled in the last 30 years.
  7. 7. The flow of ice from glaciers in Greenland has more than doubled in the past decade.
  8. 8. At least 279 species of plants and animals are already responding to global warming, moving closer to the poles. </li></li></ul><li>Future Effects of Global Warming<br /><ul><li>Deaths from global warming will double in just 25 years, to 300,000 people a year.
  9. 9. Global sea levels could rise by more than 20 feet with the loss of shelf ice in Greenland and Antarctica, devastating costal areas worldwide.
  10. 10. Heat waves will be more frequent and intense.
  11. 11. Droughts and wildfires will occur more often.
  12. 12. The Arctic Ocean could be ice free by 2050.
  13. 13. More than a million species could be driven to extinction by 2050. </li></li></ul><li>What We Can Do<br /><ul><li>Use Wind Energy
  14. 14. Reduce CO2 Emission
  15. 15. Action is essential at every level
  16. 16. Individual
  17. 17. International
  18. 18. Plant & Save trees
  19. 19. Recycle the product</li></li></ul><li>My View<br /> I do strongly agree that with that all the privileges we are given through industrialization we need to use our intelligence to make sure all the processes we use to make our lives easier are efficient and have very little harm on our environment.<br />
  20. 20. Thank You !!!!<br />
