1. Global Warming is the increase of temperature in the world.
2. Yes i believe in global warming because the polar ice caps are melting.
3. One of my evidence is that the climate record how carbon dioxide increase and it makes the temperature go up, My second is the study of ancient ice cores from Antarctica it is possible to compare atmospheric concentrations of the dominant greenhouse gas, carbon dioxide (CO2) in the atmosphere with temperature variations over the past 400 thousand years of the earth's history,and glaciers and mountain snow are starting to melt very fast.
4. Examples against global warming is that all predictions are base on computer models, the modest amount of global warming would be beneficial to the world and many people believe that the greenhouse gas has been apart of the earth's atmosphere for a very long time.
