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. If carbon dioxide levels go up, so does the Earth's temperature. He states that this is important because the temperature of the Earth affects the weather as well as the disappearance of the polar ice caps. He makes this point about carbon dioxide levels to encourage the people of the world to do something before global warming becomes an even larger problem.

It kinda shows how in life some people have done bad things but if they change their ways starting now they can still be part of the good in the world. I hope this helps :))
