Climate change review

Nowadays global warming is a major problem facing mankind; some people see at as a big deal and others don’t really care. global warming means the heating up of the earth’s atmosphere due to the greenhouse emissions. The results of global warming can be destructive; many natural disasters were caused because of global warming.
The documentary film presented by Al Gore shows many statistics and results because of global warming. It showed that the first problem caused by global warming is the heat increase and the melting of glaciers, and generally the increase in temperature of the atmosphere. The second problem is the emission of carbon dioxide which affects the atmosphere. In the class we learned how to find out how to calculate our carbon footprint and how this affects the atmosphere. My carbon footprint was 4.67 which means that I emit carbon dioxide 4.67 times than the amount that I should emit, I need 4.67 earths.
Is there a solution for this issue? Many people think that if we try to emit less carbon dioxide and stop polluting the earth it will help in reducing the affect of global warming. Roger Ebert agreed with Al Gore in many ways and he suggested some ways to help, ways which could be done by each individual. We can do this by switching to alternative energy like solar, wind, tidal, and nuclear if possible. We should change to electrical cars and save energy in our houses. Another critic Tony Medley did not agree with Al Gore when he stated that human actions are responsible for global warming and that humans can stop it. Tony thinks that the movie was scientifically presented and it had some emotional ideas; on the other hand he mentioned that some points were good.
In my opinion I think that this issue has been discussed a lot and many people have argued about it. I think that global warming is overrated and it was given more time than it deserves.
