Al Gore shows that the levels of atmosphere carbon dioxide have varied throughout Earth's history. In the graph, the carbon dioxide levels have significantly increased recently. It is the highest the level has ever been and is expected to continue to rise. In his presentation, he shows that the levels of carbon dioxide in the atmosphere have a direct correlation to the temperature of the Earth.
