Global Warming causes

There are many causes that affect the atmosphere surface which called the Global Warming (greenhouse effect).
The greenhouse gases which are carbon dioxide and methane that gases which came from the burning of fossil fuel like oil, petrol, gas... and other gases. These are the main causes of the global warming. However, the studies still in progress to find other causes about it.

Summary of the Al Gore Presentation

Albert Arnold "Al" Gore was the forty-fifth Vice President of the United States. He wants to show to the people the dangers of the change in the environment and how it is affecting our plant. He wants also to tell us that we are responsible of the changes and the main reason for that is our recklessness about the environment. We are cutting the trees around the world and build new building, we are also built a lot of industry and transfer the oil under the sea which is polluted the environment. These things are raising the temperature on the plant to cause melting the glaciers around the world this may cause some islands to sink in the future. 40% of the people get their drinking from the Himalayas Mountains and if the ice melts there it will be a series problem. We can see from the graphs that when the CO2 increase the temperature is increases also. Al Gore explains the polar ice cap melting and how it is effecting on the polar bears. He said when the temperature rises in the ocean the ice becomes weak and can not carry the bears. They will not find place to rest and that will be deadly for the bears. Al Gore is warning that a new disaster is coming and we will face huge impacts. The film was really great and effecting; because he shows the effects of the climate change and show us the evidence by photograph.

My opinion about Al Gore presentation

The name of the film is an Inconvenient Truth by the lecturer Albert Arnold "Al" Gore. It was a great film and I strongly agree with him. I found the most important point which compelling me when he said that we know smoking cause cancer and we still smoking it. It is the same as global worming we know it effected in the plant and our industry still pollute the earth. Al Gore’s comments were great and there isn’t any point which I disagree with him. The music was very nice and the images were explained what he was telling. On a scale of 1 to 10 I gave him full mark because what he said was very important and the way of his presentation was fantastic. Finally I want to say for everybody to take this subject very seriously and to learn more about it also to tell the people who doesn’t know about it because it is our future.

A COOL CITY

Some of the problems associated with economic development when the industrial revolution is started which are increasing in energy consumption, increasing the amount of Carbon Dioxide and traffics. So, if we do not solve these problems properly we need another earth. We need to decrease 0.5 of carbon dioxide to live within the capacity of a single earth. In Japan during the last 30 years GDP (Gross Domestic Product) has gone up 100 percent while energy efficiency has increased 37 percent and oil consumption has decreased 80 percent. 90 percent of carbon dioxide emitted into the air comes from the building and transportation. A Cool City means a Model City and SDCJ are from Japan will build it. There are three types of transportations that will be used in Cool city which are hybrid, water transportation. There are various zones in the city which are business, residential and culture. There are some techniques that will reduce heat such as water, trees and roof membrane. It is expected that resident building would reduce CO2 by 30 percent and other buildings by 50 percent. Finally, the percentage of reduction of CO2 emissions claimed in the video was 60 percent.

Carbon Foot Print

A definition of carbon foot print is the total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in equivalent tons of carbon dioxide (CO2). My earth equivalent is 8.23 and it is too high from the links http://www.myfootprint.org/ and http://footprint.wwf.org.uk/ . My friends equivalents are too high also 7.59, 7.56 and 6.77.
I think that using my car every day even small distance contributes to atmospheric pollution. And also another reason that is when I am sleeping I don’t turn the out side light off. Furthermore, I am one of the people how doesn’t recycles.
My recommendations of how to reduce carbon footprints is to recycle things like mobile phone, TVs and cars. They can renew these things and used it again or to make another things. Other recommendations are that to use another sources of energy like wind and sun.
