Al Gore is, in my mind, a leader in American politics, and a leader in stopping global warming. Before you can fix a problem, the population must be educated, and that is exactly what Gore did when he created, "An Inconvenient Truth".
In Paragraph 21 of his Noble Peace Prize acceptance speech, Gore call out the United States and China for not doing enough to limit their Carbon Dioxide emissions. "But the outcome will be decisively influenced by two nations that are now failing to do enough: The United States and China", Gore states when blaming world powers for a failure to act.
That statement was the most important one of Gore's entire speech. The United States and China have a large affect on how other countries react to conflicts and problems, and global warming is a problem that every human has to worry about. The CO2 emissions that we pump into the ozone, will endanger the entire world.
As Americans, it is our responsibility to pressure our governing officials to act, and it is their responsibility to pressure the global community to make better decisions that will help the enviorment. If we can set an example as an efficient community, then the rest of the world will follow in our footsteps.
