Al Gore used visual aides in many ways to emphasize points in his presentation. Some of these visuals were humorous while others were very serious. Overall, I thought that these visuals were used very appropriately and were a good way to keep the audiences attention. They were also a good way to make points clear for people who didn’t know much about global warming.

One of the visuals that I remembered was the graph where Gore used the mechanical lift to reach the top of the chart. This graph was used to show carbon dioxide concentrations versus time. Gore said that many people believe that the earth goes through cycles of increasing carbon dioxide and then it decreases again. These people also say that we are simply in a time of increasing CO2. Gore used this graph to show that the present carbon dioxide concentrations are higher than they’ve ever been. He doesn’t believe that we are just in a cycle of increasing CO2. He thinks that this insanely high amount of carbon dioxide is enhancing global warming.

Another set of visuals that were used were the pictures of various landmarks around the world. He showed pictures of what these landmarks looked like in years past, and what they look like today. These pictures showed drastic changes, whether it was a melting glacier or a dried up lake or river. One of these pictures showed a picture of a lake that was almost dried up. This lake was previously used for drinking water for the areas around it.

Gore also used another set of visuals to show what could possibly happen to our planet if global warming continues at the current rate. These pictures showed how much ocean levels would rise if glaciers continue to melt. If all of this ice melts, ocean levels are going to rise drastically. This could possibly put part of Florida and New York City under water. This could drive people out of their homes all around the coastlines. One of the most affected areas would be Western Asia. Rising water levels would force millions of people to find a new home. Consequently, areas that aren’t under water would be even more populated, causing even more problems.

All of these visual aides were used to better emphasize a point. For me, they made the problem, of global warming, more clear. I never realized how widespread this problem is. I think that this presentation was much better by using visuals than using words. Using words can sometimes lose people’s attention, but these pictures kept my attention during the whole movie.
