1、Global Warming 論文The global warmingAs the development of our modern society, theglobal 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 warm

2、er 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 tohuman?s activities, producing the green house gases such as carbon dioxide, met

3、hane 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 ecologicalenvironment. Mounts of carbon dioxide produced thehuman being ourselves is a huge number. At last cen

4、tury, 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 develo

5、p our industries at the cost of our precious earth.The human?s irresponsible activities have causemany 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 deteriora

6、tion, 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, themounts of carbon dioxide absorbed by ocean plants is declining. In the other hand, the income of fish man has bee

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

8、is just the sources of living in thelocal 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 Deser

9、tification 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 clos

10、ing.In this century, the temperature is forecast to grow1. 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 Nationsscientists. ?the upper temperature range is significantly higher, because we now

11、 think we could be emitting 35 to 40 gigatonnes of C02 a year by 2100? (a gigatonne is lbn 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.

12、 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 h

As the weather is becoming wormer, the glaciers ofAntarctic and Arctic are melting. The direct result of this is sea level rise. Thi

About 3000 cities are located in lower altitude area (the altitude is lower than lOmeters).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 are

Titanic is a big disaster to our human caused by floating ice. The animals also cannot avoid the effect

The warm weather causing the grain reduction makesimpossible Millennium Development Goal of poverty reducti

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 warmi

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 mon
