Have you ever wondered about Global Warming? I am a 14 year old kid and I feel like I need to point some things out. The movie where Al Gore has his presentation of Global Warming, the huge chart he has showing CO2 emissions well do you notice that the little line goes up and then back down and then back up? That is because it is a cycle. I watch the Discovery channel alot and I thought of something. Ok, the glaciers melt well that is putting alot of fresh water back into the ocean. There is a difference between Freshwater and Saltwater, Saltwater is more dense so with the new freshwater in the ocean that could change the currents. Once the currents change so does the weather near the coast. It would start to get colder because the new currents, and would most likely send us into another ice age just like the years before and before and before. This is showing how its a cycle.
