  1. thank you, Sir Kong.
  2. There's some assumptions that presented in this article.
  3. One assumption meat is due to the fact that the
  4. prediction models that created using the transform the past doesn't
  5. mean any implementation off new protocols will affect the prediction.
  6. Quoting from the article, one of the iconic climate models
  7. and one of the first brought the issue of climate
  8. change too broad Public attention was published by James Hansen
  9. off NASA in 1988.
  10. However, his predictions for temperatures after 1988 were 50% higher,
  11. actually global mean temperatures in those years.
  12. This is in part because Hansen did not anticipate the
  13. Montreal Protocol, a treaty that went to effect in 1989
  14. on which banker for all cupboards, which are both in
  15. greenhouse gasses.
  16. As you can see, the author has mentioned, such prediction,
  17. models are not always correct.
  18. In this case.
  19. The prediction model published by Hanson overestimated the global mean
  20. temperature due to the implementation off the Montreal Protocol.
  21. The Montreal Protocol is an international agreement in 1987 when
  22. it was designed to stop production and import ozone depleting
  23. substances and reduce their concentration in the atmosphere to help
  24. protect the Earth ozone layer.
  25. Due to this, the actual value of greenhouse gasses was
  26. actually less than what was estimated, resulting in a lower
  27. mean temperature in the past few years.
  28. Treaties such a security protocol in 2005 Paris agreement in
  29. 2016 have been implemented to cut human emission off the
  30. greenhouse gasses.
  31. Another assumption made is that there must know there must
  32. be no drastic change in human mission.
  33. Like I mentioned prediction models that created using trends from
  34. the past.
  35. A drastic change in human mission will result in the
  36. prediction model being inaccurate.
  37. Once again, that concludes the uncertainties assumptions.
  38. Are we passing your time over to usually, who will
  39. be liberating more on the implications and importance off this
