The global warming

As the development of our modern society, the

global warming came into our eyes, became a hot topic. At the same time of enjoying modern life, we also get the punishment of environment. People around the world may feel that the climate has been getting steadily warmer and warmer in recent years. We should pay more attention to the global warming not only because it is important for us, but it concerned about the future of our descendents. The major reason of global warming is due to

human?s activities, producing the green house gases such as carbon dioxide, methane and water vapor, which trap the energy from the sun. Recently, the sharp increasing of population is one of the main reasons. Meanwhile, this is biggest threaten to the balance of the ecological

environment. Mounts of carbon dioxide produced the

human being ourselves is a huge number. At last century, we spare no effect to develop our industries, pumping the oil, cutting the Forrest, and burning fossil fuels. On the contrary, we forget the basic foundation of developing our living environment. Consequently, the environment is becoming worst and worst since the end of last century. We develop our industries at the cost of our precious earth.

The human?s irresponsible activities have cause

many environmental problem. Consequently, this environmental phenomenon is also one of the main reasons of the global warming, such as soil desertification, the marine ecological environmental deterioration, and careless deforestation. It is known to us that the Gulf oil spill have damage the ocean environment greatly by killing many ocean plants and animals. As the result of these, the

mounts of carbon dioxide absorbed by ocean plants is declining. In the other hand, the income of fish man has been affected directly. According to a document, the forests is damaged at a rate of 20 hectare every minuets in the world. The forests in Brazil are called as the lung of earth, playing an important role in the way of balancing the temperature of the whole world. This is the apple of our eyes. But it is just the sources of living in the local people?s eyes. They burned the forests only for one year?s crop harvest. In the history of china, one famous city Dun Huang is known as international business trade center; however it is just a lonely town standing in the desert now. The square of soil Desertification is increasing every year by 10 hectare every minuets, equivalent to 15 football field. Unfortunately the earth is at the warm period according to one scientist?s study. Orbital track of the earth is more like a circle. In the other words, the distance between the earth and the sun is closing.

In this century, the temperature is forecast to grow

1.4℃-5.8℃ measured by IPCC (UN?s International Panel on Climate Change). The effect of global warming could be twice as the worst situation feared by United Nations

scientists. ?the upper temperature range is significantly higher, because we now think we could be emitting 35 to 40 gigatonnes of CO2 a year by 2100? (a gigatonne is 1bn tonnes),said by Dr Mike Hulme, a climate researcher at the University of East Anglia in the UK. A 10-degree warmed world would be a dramatically different world.

There are many result of the global warming. U.N. Panel finds climate change behind some extreme weather events. ?A hotter, moister atmosphere is an atmosphere primed to trigger disasters,? said Michael Oppenheimer, a Princeton University climate scientist and a principal author of the new report. “As the world gets hotter, the risk gets higher.” In recent years, deluge and cyclone became very common. For instance, the flood in Thailand continues

about 3 mouths this year, causing some 500 people?s dead. As the weather is becoming wormer, the glaciers of

Antarctic and Arctic are melting. The direct result of this is sea level rise. This is huge threaten to many island and offshore cities. About 3000 cities are located in lower altitude area (the altitude is lower than 10meters).

However, the sea level is forecast to be higher about 20 to 50 centimeters in 2100. And about 10% of the whole world population lives in the dangerous area. In the last century, the sea level was increasing at rate of one or two millimeters every year. At the same time of sea level increasing, the melting glaciers add more danger to the Navigation. Titanic is a big disaster to our human caused by floating ice. The animals also cannot avoid the effect of global warming. Bears have weak up several mouths early from winter sleeping. It is really hard for small baby bear to survive the winter.

Global warming threatens to reverse human progress. The warm weather causing the grain reduction makes

impossible Millennium Development Goal of poverty reduction. The predictions of the effects of climate change in poor countries are more seriously. The poor counties will experience more flooding, declining food production, more disease and deterioration of entire ecosystems where many of the world?s poorest people depend. It is reported that global warming, more than wars, will displace millions of people. Unbelievable, when the weather become wormer, the born rates will decline due to the reduction of Sperm activity. Warming is also a big challenge for children and old people because it will cause more problems among the respiratory system of them.

Without any doubt, the governments have great responsibility to deal with the global warming. Government should make more law about industrial emission. At the seam time of earning money, some factories should have to deal with pollution. All the countries who signed up ?Kyoto Protocol? should put more efforts to reduce

industrial emission. All the counties in the world should put down the political problem and work together. We can also do some favor in daily life. When you go outside, try to

ride bicycle or take public traffic instead of driving personal car.

The earth is the only home of us. We should try our best to protect it. The global warming prevents the sustainable development. We should work together to deal with it on matter what kinds of difficulties are in front of us.
