摘要:地球已经经历的太多太多了,改变过去几十年。这与一般的气候突变相关。这是关于自然灾害的新闻,许多国家已经遭受了这样的灾害,例如地震,海啸,洪水,大量的旋风,干旱等。

What is global warming什么是全球变暖


混合粉(2004,第4页)注意到,太阳辐射到达地球,三分之一被反射回太空,其中一些是被大气吸收,剩下的被陆地和海洋吸收,因此,地球表面变暖每年由红外辐射引起的海平面崛起之后当然在格陵兰和南极洲冰层融化。Maslin (2004, p.4) note that one third of this solar radiation hits the earth and is reflected back to space, some of it is absorbed by the atmosphere but the remainder is absorbed by the land and oceans, as a result, the earth surface becomes warmer and warmer every year by this infrared radiation which causes the rise in sea levels after of course the melting of ice sheets in Greenland and Antarctica. http://www.51lunwen.org/EnviromentalEngineering/ As a consequence, many islands and coastal areas ending up more exposed to storm damage or even underwater. Houghton et al. (1990)This is because; greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature and warming the earth by 35˚C. Therefore some other scientific explanations of this warning sign are that, the temperature of the earth is controlled by the balance between the input from energy of the sun and the loss of this back into space. Therefore, these atmospheric gases are very critical to this balance and scientists describe them as greenhouse gases.


 CAUSES OF GLOBAL WARMING 全球变暖的原因    

There are a lot of causes of global warming. Former Vice President Al Gore claimed that global warming is forcing ocean temperature to rise, which is causing storms, including cyclones and hurricanes to intensify (Jeff Poor 2008). The greenhouse effect is when the sun heats up the earth in the path of which the atmosphere is being passed through by the solar radiation and it is then absorbed at the earth’s surface (ECO Centre staff 2004). Most of the gases emitted are trapped and therefore the earth is losing less heat which results in global warming. And this is a bad thing as the earth will warm up faster than expected and causes every living thing to suffer. However, the main cause of global warming is due to human activities. Humans are mostly responsible for global warming over the past few decades. It is due to their thoughtless and irresponsible nature. Humans have burn a large amount of fossil fuel for their own usage in their daily life. Deforestation has been going on for a long time, as the population is increasing rapidly more trees are being cut down. More lands are being cleared for the use of humans needs. So there are not enough trees to absorb the carbon dioxide and therefore the carbon dioxide in the atmosphere increases. In addition, carbon emission has the highest emission rate and concentration; it contributes mostly to the global warming (Allen & Shonnard 2002, p. 10). It is mostly vehicles and airplanes that release this type of gas as exhaust. The chlorofluorocarbons and other gasses are to blame for the depleting of the ozone layer (ECO Centre 2004). Which has been protecting us from the harmful ultra-violet radiation of the sun and it could damage. Chlorofluorocarbons are usually emitted by refrigerator, air-conditioner and spray cans that are made by manufacturers.



Now survival is a challenge for humans and the other living things on our planet. The climate change happens naturally but because of human activities the change is happening faster than is expected. Human intervention is a consequence of climate change which causes gl论文英语论文网提供整理,提供论文代写英语论文代写代写论文代写英语论文代写留学生论文代写英文论文留学生论文代写相关核心关键词搜索。
