Global warming issues

Global warming is the change of the average temperature of the earth's atmosphere due to the increase of greenhouse gases resulting especially from pollution. If this problem doesn't decrease in the next years we will live in  an unhealthy environment.

The main problem that we are facing now is the lack of knowledge that people have about global warming. Most people think that global warming is just a myth that tree huggers use so people can think about nature and what mankind is doing to it.Moreover, global warming is affecting many parts of the world. “First there is the increase of temperature that causes the ice to melt which leads to a rise in water level.”(wikipedia.com) This could cause low land areas to flood  with water that will destroy plants, animal habitats and cause people to leave the area. Also the increase of temperature causes lakes to dry. Finally another problem and it is the largest cause of global warming is Co2 emissions. “This gas, CO2, collects light and heat, produced by the sun, and this makes the earth warmer”(http://library.thinkquest.org).

There are many different ways and solutions to prevent global warming. First of all we have to educate people so they have more information about global warming this is the first step. After education people will be aware about it and will try to reduce their carbon footprint. Second of all, Co2 emissions should be reduced from cars, industries and cities. We also should reduce the use of fossil fuels. Moreover, there are many solutions provided by companies and countries, for example cool city which is mainly a 1-km in diameter city which will have more environmental housing and resources. “Cool Cities not only bring real solutions at local levels they also showcase solutions for others to model and build leadership to ensure solutions are implemented at state levels and nationwide”(www.coolcities.com).

In my opinion I think that people are over reacting about global warming. I also think that most of the solutions are short term rather than long term solutions especially cool cities, I don’t think cool cities are a solution; they are  just rich people’s toys that they can live in and think that they are committed to this problem.

Cool city

Since the start of the industrial revolution we are experiencing a sharp increase in economic development and  due to this increase there are problems such as traffic congestion, population pressure and energy consumption. If these problems aren’t solved as soon as possible we need to find another earth to live in; to solve this problem we have to decrease the amount of carbon dioxide emitted into the air by 50% so we can live in the earth we are in now. In Japan during the last 30 years GDP has doubled while energy efficiency has increase by 37% and oil consumption has decreased by 8%. 90% of carbon dioxide emitted into the air comes from building which is 55% and the 35% from transportation. 

Cool city is an environmental-friendly citys which is developed by SDCJ in Japan and they will build environmental cities in the Gulf region. The cities will be linked with a public transportation system that will be using solar water taxis, hybrid-cars and light-rail transit. The cities contain three main zones residential, commercial and business. The cities will use various techniques to reduce heat like tree planting, water channels and wind power. There is also a membrane that covers certain areas that use techniques that filter light and heat. They expect  CO2 reduction from two types of buildings eco tower which is reduced by 50% and eco residential which is reduced by 30%. Finally the overall percentage of CO2 reduction will reach 60.

In my opinion I think building small cities that will only be used by rich people is not a long term solution We should apply these technologies to cities rather than small areas with a 1-km radius to see them work.
