6. Climate Change Part 2

7. Climate-Feedback Mechanisms
So far the climate-feedback mechanisms we discussed have magnified the temperature rise caused by the buildup of carbon dioxide.
Because these effects reinforce the initial change, they are called positive-feedback mechanisms.
However, other effects must be classified as negative-feedback mechanisms because they produce results that are just the opposite of the initial change and tend to offset it .

9. Some Possible Consequences of Global Warming
Global warming can alter the distribution of the world’s water resources and can effect the productivity of agricultural regions.
It can cause a rise in global mean sea level.
By changing weather patterns, global warming could cause a higher frequency and intensity of hurricanes.
It can cause shifts in the paths of large-scale cyclonic storms.
Global warming could also cause changes in frequency and intensity of heat waves and droughts.
