  1. I think so from my project, I did how fossil fuels contribute to climate change.
  2. Fossil fuels are not renewable sources of energy and are formed
  3. from the decomposition of plants and animals,
  4. and when they are burned, they produce large amounts of carbon dioxide
  5. and due to the increasing carbon dioxide
  6. in the atmosphere,
  7. the more he is retained in the earth's temperature begins to rise.
  8. And some examples of fossil fuels are coal and natural gas.
  9. Greenhouse gasses are heat trapping gasses in the aid in the greenhouse effect.
  10. Carbon dioxide and water vapor are the
  11. most important greenhouse gasses in our atmosphere.
  12. And they are considered the most important because
  13. water vapor traps heat and
  14. traps heat from the earth's surface in the lower atmosphere,
  15. and carbon dioxide is the most abundant in the atmosphere
  16. and they both trap heat and it stays in the atmosphere
  17. longer.
  18. Most of the gasses can call most of
  19. the gasses that are involved in the greenhouse effect
  20. can cause more warming than carbon dioxide.
  21. But since they are less abundant in the atmosphere,
  22. they cause less warming overall.
  23. And global warming is
  24. caused by the increase in greenhouse gasses
  25. and global warming is a gradual increase in earth's average temperature
  26. and earth naturally goes through warming including phases.
  27. But the increase in human activity like
  28. burning fossil fuels has contributed to their lives
  29. and greenhouse gasses and the rapid warming of the earth.
  30. The increase in Earth's temperature has already had an effect on the environment.
  31. The warming of the oceans is causing the polar ice
  32. caps to melt and the sea levels to rise.
  33. And a consequence of global warming can be seen in the polar bears,
  34. because the polar bears would rely on the sea ice to hunt for food,
  35. and they are melting
  36. and climate change is the result of global warming.
  37. Climate change is a long term change in the weather patterns and temperature.
  38. An example of climate changes can be seen in the oceans,
  39. and the result of burning large quantities of
  40. fossil fuels and producing a lot of carbon dioxide
  41. is raising the city of the oceans and the oceans becoming more
  42. so they can have an impact organisms that live in the ocean,
  43. and these are my sources.
