What we found doing this program is that as CO2 levels increase, ice levels decrease due to the greenhouse effect. The CO2 traps the heat in not allowing as much heat to escape our atmosphere. This is shown in the third graph. Using our program we found that at the current rate of decay of the ice it will be at about 3000 feet by the year 2030 which is about 10,000 cubic feet less than it is currently. This is obviously not good because it means loss of habitat for ice dwelling animals. It also means a rise in sea levels will occur which will cause loss of habitat for other land animals. Another negative effect of the melting of the ice is loss of drinking water and water used for watering crops because many people rely upon the natural, regular build up (in the winter) and melting (in the summer) for these things.
