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.

Cool Cities

Since the start of the industrial revolution there have been some problems associated with the economic development such as increase in pollution, increase in energy consumption and increase in CO2 emission. These are liabilities towards the industrial revolutions so we would need something that is not possible, another earth. In order to solve these problems we will need to reduce the emission of CO2 by about 50%. Seattle had reduced the emission of its CO2 by 60% by building green houses and using alternative fuel in vehicles. In Japan during the last 30 years GDP (Gross Domestic Product) has doubled, while energy efficiency has increased by 37% and oil consumption has decreased by 8%. 90% of the CO2 emitted in the air is produced from buildings and transport. A cool city is a friendly green city with a minimal emission of CO2; it is being built by the SDCJ, a group of Japanese companies. The three types of transportation that will be used in the Cool cities are light transit trail/monorail, solar water taxis, hybrid cars and SDCJ are also using heat-reducing techniques like: planting trees, roof top membranes and waterways. There will be three main city zones: Commercial, Cultural and Residential. They are expecting to reduce the percentage of Eco-towers emissions by 50% and the Eco-residence emissions by 30%. The overall expected reduction of CO2 is 60%.

My opinion

I think this a good leap towards solving the problem of global warming and the emission of CO2. The main disadvantage of this project is its price; I am sure that it costs them a fortune. Another problem is who will really care about living in an expensive place, where CO2 emission is at a minimum.
