Climate change

  1. 1. Can WE change it ?
  2. 2. <ul><li>“ Climate includes patterns of temperature, precipitation, humidity, wind and seasons. While &quot;Climate change&quot; affects more than just a change in the weather, it refers to seasonal changes over a long period of time. These climate patterns play a fundamental role in shaping natural ecosystems, and the human economies and cultures that depend on them.” </li></ul>
  3. 3. Proof that there are changes in Earth’s Climate….. <ul><li>World’s Average Temperature has risen by about 0.74 °C over the last century. </li></ul><ul><li>Observed decrease in Snow and ice Extent. </li></ul>E.G. annual average Arctic sea ice extent has shrunk by about 2.7% per decade
  4. 4. Why We Must Care? <ul><li>Because of Climate Change, Sea Levels arise….. </li></ul><ul><li>causing coastal lands to diminish. </li></ul><ul><li>We’re Experiencing more droughts because of climate change. Drought causes many other problems like Energy Problems, Water Resource and availability Problems, Food Supply Problems and Problems in Human Health. </li></ul><ul><li>Climate Change increases the Intensity of Tropical Cyclones. </li></ul>
  5. 5. O ther Impacts of C limate C hange Global Climate Change Impacts according to IPCC
  6. 6. <ul><li>It happens because of us…. </li></ul><ul><li>And Destructive Human Activities </li></ul>Why all Of this happens HUMANS
  7. 7. Because of human activities Greenhouse Gas Emission Increases. To Much Greenhouse Gases Cause warming that results Climate Change. Most scientists agree the main cause of the current global warming trend is human expansion of the &quot;greenhouse effect&quot;
  8. 8. Greenhouse Effect
  9. 9. <ul><li>And If This Greenhouse effect gets worse… </li></ul><ul><li>Our Earth will be like the planet Venus… </li></ul>Too Much GreenHouse Effect: The Atmosphere of Venus Is Nearly all carbon dioxide producing a runaway greenhouse effect and a surface temperature hot enough to melt lead.
