An Inconvenient Truth-opinion


An Inconvenient Truth movie was interesting because it showed us new information about the global warming nowadays with a good method that was given by Al Gore. As well the other things which made it interesting were that Al Gore showed us the danger of this phenomenon it is still growing in this world. Ice melting which is the major problem that can cause other problem to follow it. The second problem is that the atmosphere.

I have learned about the climate change effect on humans, animals and also the environment which could eventually put us in danger. Another thing that I have learned from this movie is that the north of the equator is one of the world places where we can look at the changes on the climate. Finally I want to say that now we can note that in both hemispheres CO2 is in creasing. The two graphs of temperature in the past 1000 years show it is really a problem for this planet.

Carbon footprint


Carbon footprint is defined as a measure of the exclusive total amount of carbon dioxide emissions that is directly and indirectly caused by an activity or is accumulated over the lift stage of a product. I calculated my "carbon footprint" by using http://footprint.wwf.org.uk/ and I got 2.41 which mean that I got an average which is lower than the UK average, and the survey goes like this: 20% for food, 22% for travel, 27% for home and 28% for stuff. Carbon footprint is the result of our acts in both individuals and society, which will finally effect the world’s climate change.
The carbon footprint is measuring the amount of CO2 we produce every day by different ways. Including almost everything we do in our lives.

The calculations of carbon footprint calculate the amount of energy we use in order to produce electricity, and usage of transportation and even food consumption and many other stuff we do.
After having an idea about carbon footprint, we should reduce it by many ways which will be mentioned later.
First, we have to increase the efficiency of our machines, and use less energy. After that we will see that carbon footprint will decrease and we will reduce the carbon emissions we produce. To know more about carbon footprint you could visit other web sites, which will help you have more information about carbon footprint statistics.

Cool City


Since the start of the industrial revolution there have been some problems associated with economic development such as increasing in energy consumptions, increases the amount of carbon dioxide and finally traffics. But if we don’t solve these problems we will need at 8%.However 90% of the carbon dioxide emitted into the air come from buildings and transportations. Cool City is a model city which is a new method of technology that is going to be build by SDCJ which is a Japanese company. The city will conclude three types of least another earth. But to decrease the amount of carbon dioxide emitted in to the air to live within the capacity of a single earth we will need about 1.5.In Japan during the last 30 years GDP has gone up 100% while energy efficiency has increased 37% and oil consumption has decreased transportation that will be used in it such as monorail station, LRT “Light Rail Transit” and water transportation whereas the various zones in the city are business, residents and culture. This city also will use some techniques that will reduce the heat from the air for example water, trees and roof membrane. There are two types of buildings in that city which are expected CO2 reduction namely commentarial building which reduction 50% and the other one called residence building which reduction 30% and the overall percentage of reduction of CO2 emissions claimed is 60%.
