3 Global warming m

  1. 1. Global Warming: Real or Not Real? <br />By: Maggie Smith <br />
  2. 2. Global warming is Real! <br />Global warming is caused by pollution from factories, carbon dioxide from rotting trees, and the burning of coal. <br />
  3. 3. Water Vapor! <br /> You probably would have never thought water vapor was a cause in global warming because water vapor makes up 60% of green house gases it does. It cause’s global warming because is contributes to the green house effect, and the green house effect cause’s global warming,. <br />
  4. 4. Arctic <br /> The arctic is feeling the effects the most. Alaska, western Canada, and eastern Russia’s average temperatures have risen twice the global average. <br />
  5. 5. Arctic Ice <br />The arctic ice is rapidly disappearing. The arctic region could have its first completely ice free summer by 2040, or possibly earlier. <br />
  6. 6. Arctic Wild Life and Cultures <br />Polar bears and indigenous cultures have already been suffering from sea-ice loss. <br />
  7. 7.
  8. 8. Who are really causing Problems? <br />China and India rely heavily on coal and if they continue to use it, it will cause environmental problems. <br />
  9. 9. Water….<br />As everyone knows the oceans cover 71% of the earth and due to global warming sea levels are risen which could destroy homes since the water will have to go somewhere. <br />
  10. 10. Islands will Disappear. <br /> Majuro Atoll is an Island, in Pacific. This island is predicted to lose 80% of its land due to the 20 inch (0.5m) rise in earths sea levels. Soon Islands will disappear if global warming does not stop<br />
  11. 11. So how is Global warming really caused? <br /> Scientist say that Global warming is cause by human activities, due to a complex process of sunlight, gases, and particles that have entered the atmosphere. But the main human activities that are causing global warming would be the burning of fossil fuels (coal, oil, and natural gases.) and also the clearing of land. <br />
