Many people believe that human activity is causing the earth’s temperature to rise. They say that this global warming will have dreadful consequences for our environment, such as drought and flooding.
The earth’s temperature is rapidly changing. As a result there has been a lot of climate change such as heat waves, droughts and floods. Scientists believe that this is the result of human activity, which is polluting the Earth’s atmosphere. This could become a disaster if governments do not act to help prevent global warming. They can act in three ways; by supporting research, by making laws and by keeping the general public informed.
Firstly, governments can support research. For example, they should encourage companies to develop vehicles that cause less pollution. They should also support alternative sources of electricity from wind and water rather than from oil and coal. As well, they should sponsor conferences to discuss the effects of greenhouse gas emissions and possible solutions to the problem.
Secondly, they should make laws that limit the amount of greenhouse gases that companies can emit. Private companies should be rewarded for following these laws. They should also be punished for creating pollution.
Finally, everybody is affected by global warming. Therefore, it is important that governments involve individuals in the problem solving process. For example they should encourage households to save as much energy as possible by using more efficient light bulbs or less hot water. They should also encourage the public to recycle, and this should be compulsory for everyone. Another way of saving energy is by public transport systems. Governments should spend money on public transport to make it as easy as possible for the public to save energy.
In summary, it is clear that there are a lot of things that governments can do to prevent global warming. They should involve companies, support scientists and encourage individuals to protect the planet.

global warming the gradual increase of the temperature of the earths lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution.
The temperature of the atmosphere near the earths surface is warmed through a natural process called the greenhouse effect. Visible shortwave light comes from the sun to the earth passing unimpeded through a blanket of thermal or greenhouse gases composed largely of water vapor carbon dioxide methane nitrous oxide and ozone. Infrared radiation reflects off the planets surface toward space but does not easily pass through the thermal blanket. Some of it is trapped and reflected downward keeping the planet at an average temperature suitable to life about 60°F (16°C)。
Growth in industry agriculture and transportation since the Industrial Revolution has produced additional quantities of the natural greenhouse gases plus chlorofluorocarbons and other gases augmenting the thermal blanket. It is generally accepted that this increase in the quantity of greenhouse gases is trapping more heat and increasing global temperatures making a process that has been beneficial to life potentially disruptive and harmful. During the past century the atmospheric temperature has risen 1.1°F (0.6°C) and sea level has risen several inches. Some projected longer-term results of global warming include melting of polar ice with a resulting rise in sea level and coastal flooding; disruption of drinking water supplies dependent on snow melts; profound changes in agriculture due to climate change; extinction of species as ecological niches disappear; more frequent tropical storms; and an increased incidence of tropical diseases.
Improved automobile mileage reforestation projects energy efficiency in construction and national support for mass transit are among relatively simpler adjustments that could significantly lower U.S. production of greenhouse gases. More aggressive adjustments include a gradual worldwide shift away from the use of fossil fuels the elimination of chlorofluorocarbons and the slowing of deforestation by restructuring the economies of developing nations. In 20__ the Bush administration proposed several voluntary measures for slowing the increase in instead of reducing emissions of greenhouses gases.

In recent years do you think the weather suddenly turned hot had the cool autumn now almost until early October the hottest day in August has reached more than 40 degrees. These is different from normal vision we have ourselves to blame the curse.
Today the term "global warming" has gradually penetrated into our life. The word sounds very academic even feel very far away from us so some people are not. In fact the effects of global warming is beyond our imagination: global precipitation redistribution glaciers and permafrost melt rising sea levels and so on. Both harm the natural ecosystem balance more threatening human food supply and living environment.
Now that you have aware of the dangers of global warming you should go to predict and improve it. Imagine if global warming is melting in the 21st century the global average temperature rising gradually so the next super storms the next round of searing heat the next major natural disasters will happen? China? The United States? Japan? No one knows. The debate has ended. Scientists around the world agree points out that the earths average temperature has increased nearly 1 ℃。 Due to all the early warning information human use of thousands of ships tens of thousands of the monitoring stations of the land and outer space satellite to monitor the earth together. Scientists will have the most advanced computer data input model to estimate the earth can face the future. Prediction results are worrying. Forty years later the Himalayan glaciers the water to the survival of millions of people are likely to disappear. The Greenland ice sheet could melt in 50 years. Currently half of the worlds biodiversity in the amazon rainforest but the rainforest is likely to turn into a piece of barren land by the end of the century. Is likely to be the future of the world like in the movie "the day after tomorrow" tornado ice fracture the temperature fell sharply ice storms freezing rain earthquake flood tsunami volcanic eruption.。. This is not a crazy fantasy if humans dont stop destroying the environment it will become a reality!
However in the warming is also good. Global warming on rice in heilongjiang province has played a large role.
Just global warming to human future development is still the do more harm than good.
In order to save the planet we should try to be: dont open air conditioning use recycled paper environmental protection to leave the meat with nitrous oxide dont use plastic bags R22 by bus; R22; Little drops of life. Actually its not difficult to environmental protection as long as you support environmental protection is the best gift you gave the planet.
Thank you all!

Global Warming
There is little doubt that the planet is warming. Over the last century, the planets temperature has risen by around 1 degree fahrenheit (0.6 of a degree celsius)。 The warmest since the mid 1800’s was the 1990s. The hottest years recorded were 1997, 1998, 2001, 2002, 2003.
The United Nations panel on climate change projects that the global temperatures will rise 3-10 degrees fahrenheit by the century’s end - enough to have the polar caps all but melted. If the ice caps melt, a vast majority of our countries borders will be under water. Monuments and great buildings, as well as homes and lives will be under water, including New York City.
So now we know what some of the causes are for global warming, how can we as individuals do our part to help save the planet?
The answer is simpler than you may think. You don’t have to go miles away from home to protest, or spend masses of money. If you try to follow the few simple steps that I shall now give you, you will have started to help us all.
Firstly, plant a tree. This could be easier than it sounds. Join or help out a local wildlife group and ask to plant a tree. Trees, when fully grown, will help keep the planet cooler. On the same point, you could protest against the demolition of the rainforests. This is the same principle, we need the trees to cool our planet and yet they are chopping them down to create roads or homes.
Something as simple as walking instead of taking the car will help reduce pollution. As well as stopping pollution, you are giving yourself exercise, something important for our bodies. So the next time you get into your car, or your motorbike, think - do I have to make this journey by vehicle or can I walk?
When you are at home, and your getting a little cold. Put a jumper on and do not adjust the heating. The extra heat produced by our homes also affects the planet. So try wearing an extra layer in winter.
If possible, buy your fruit and vegetables from local suppliers. And try to avoid imported goods. The more foreign food that we import the more pollution from aeroplanes and boats it will create.
Keeping to the speed limit can also help the environment. The more you speed the more petrol you are going to use, making the pollution higher. Also, SUV’s make about six times their own weight in CO2 each year. A small efficient diesel car covering the same distance not only uses much less fuel; it makes two thirds less.
If possible use solar energy, after all it is free; all you need to buy is the equipment. You can get much of your hot water and heating from the sun and even generate electricity.
Reduce, reuse and recycle. Only buy what you need; don’t stock the cupboards with things you may or may not use. Reuse whatever you can, like containers and paper, and recycle what you cannot reuse. It really is as simple as that.
Finally turning off unused sources of power such as televisions and heaters will help the environment, as well as save you money.
If everybody stuck to these rules, we would be doing a great thing by protecting the earth. So please take into consideration what I have said, and try to do your part. After all, it will be our next generation that will feel the effects.

The topic of global warming is attracting the attentions of countries all over the world. This global warming is on such a scale that it will wreak havoc on both poor and rich countries. It could even make large sections of the earth uninhabitable.
What have caused global warming? The theory and evidence ply suggest that human-related emissions of carbon into the atmosphere is causing, and will in the future cause, significant global warming.
How we should fight global warming? We should be taking active steps now to curb emissions and we should be engaging in international co-operation to do so. A simple natural way to fight global warming is to have escalating Taxes on carbon emissions. There is a simple reason why this is the ideal remedy: carbon emissions into the atmosphere constitute a nuisance to everybody on the planet; so those who make this nuisance should pay for their actions. A further recommendation is that there should be large-scale government support for research into new technology that will reduce carbon emissions.
China is the rising economic star; and if it also wants to assert world leadership status, it is a good opportunity for China to show the world that it has a moral commitment and the will to fight global warming.
