  1. I think that green house effect and global warming are not the same, but I can say that they have relations to each other. The reasons of having global warming is the green house effect.
    In our daily life, there are many human activities contribute to global warming. For example, we always turn on the air-conditioners, that release many hot gases out. Second, there are many transportations such as private cars, trucks, buses or taxis had released many toxic gases. Third, there are also many factories release many toxic gases too. These gases can damange the environment and air quality.
    The global warming can affect us. It will increase the temperature. That becomes very hot. Therefore, it is quite hot in winter nowadays recently. Also, the air quality will become worse and worse. Because there are many toxic gases everywhere. That makes the quality of air worse. We may breath difficultly and uncomfortable.
    So that we need to protect our earth, we should make a good environment to stay our healthy.

  2. I agree with Burgundy Li. Green house effect and global warming are not the same. Because of the green house effect, so there is global warming in the earth. There are many problems cause to the global warming. For example, many people cut down the trees, then there are less substance to absorb the carbon dioxide. Also, there are many things which need to use fossil fuel to give them energy. They also release many toxic gas. The gas affect the temperature of the earth. It becomes very hot ,it caused global warming. We will lose our winter later on. Finally, we should do some things to protect the environment.

  3. Greenhouse effect and global are totally not the same, however they are inter-related.

    Greenhouse effect is a natural phenomenon, which means the atmosphere will trap the sunlight heat in the earth and keep the surface of the earth warm. It is terrible if there are no greenhouse effect occurred in the earth. The earth will become very cold.

    Global warming is occurred by the human activities. Large amount of heat will be produced from some of the human activities and because of the greenhouse effect, the heat come from the sun and the heat produced by the humans are also trap in the surface of the earth. This makes the environment become hotter.

    The major reason of global warming is because of burning fossil fuels. When burning fossil fuels, large amount of carbon dioxide will be produced. And carbon dioxide is a kind of high temperature gas this helps the global warming effectively.

    And other reasons are something we do not have a great care on it. Like, always open the air-conditioner, deforestation and less plant to have the photosynthesis to release carbon dioxide.

    Global warming is getting more serious. The temperature of the earth is getting higher and higher. People feel hotter and hotter. It this problem continues, one day, the temperature of the earth will rise to a temperature which human cannot survive. Therefore, it is very important to deal with this problem as fast as we can.

  4. In fact greenhouse effect and global warming is not the same. Greenhouse effect is a normal thing for protecting the human and keeps us warm. Furthermore thinning of the ozone layer in the atmosphere enhances the greenhouse effect, resulting in global warming.

    In recent year, the global warming is getting serious, because of our human activities. The most serious problem of us is the low eco-awareness. We waste the energy and we use the things which release carbon dioxide which lead to global warming constantly. If we keep on using these things in a not in need condition, the global warming will totally “control” our life.

    It influences not only human activities but also ecosystems. The temperature rises and it will rise in sea levels, because of the melting of the snow and ice cover and the thermal expansion of sea water. It leads changes in climate, ecology, bleaching of coral or even effects on agriculture and food supply. It will affect the human! Therefore we must protect our living environment, don’t do the thing which hurt the earth anymore.

  5. I don’t think greenhouse effect is same as the global warming. I think greenhouse effect is just a natural process, which help human to live. For example, the main use of greenhouse effect is to trap heat in the atmosphere to help the earth keep warm. However, when human do something as generating electricity, too much greenhouse gases is produced and more heat is trapped. Through a long period of time, the earth become warmer and warmer, which we called global warming.
    How it affect us? In factm increasing in 1 degree Celsius would cause dying in plants, the increasing of storming, and also the increasing of price in some kind of food. Besides, the increasing in temperature cause more people to turn on the air conditioner, then cause a more serious global warming.

  6. I think greenhouse effect and global warming are not the same .
    Greenhouse effect is a good effect . The atmosphere trap heat from sunlight and keep the earth warm . But nowadays the atmosphere is becoming thicker and thicker , too much heat from the sun is trapped , the earth become unusually warm , global warming occurs .
    Global warming occurs because of some human activities , for example , abuse air-conditioner , using vehicles etc . Because of global warming , some scientist said that winter may vanish decade years later . The ice in north pole and south pole are melting , penguins and polar bears become endanger animals .
    In order to save our own life and the animal’s life , we should do something to reduce global warming . We should use fewer air-conditioners , take more public transport etc .
    If everyone put effort on reducing global warming , there will be a big change . So , let us take action together !

  7. I think that green house effect and global warming are not the same.
    First, Global warming is the increase in the average temperature of Earth's near-surface air and oceans since the mid-20th century and its projected continuation.
    The greenhouse effect is a process by which radiative energy leaving a planetary surface is absorbed by some atmospheric gases, called greenhouse gases. They are different. geenhouse effect is the couse, and the globle worming is the result. we use to have geenhouse effect and then leads to globle worming.

    The reason that cause globle worming is because of humen. People use lots of things such as hair sprayer, jell, the pollution of turn on the conditioner...etc which will release out toxic/greenhouse gages which harm the ozone layar such as carbon monoxide, sluphur dioxide,methane, nitrous oxide...etc, then cause globle worming.

    Globle worming may cause the increase of temperature.The predicted effects of global warming not only impact the environment, but human life as well. Effects of global warming on the environment include glaciers, ecosystems, ocean currents, and sea level. Impacts on the human level include financial matters and the spread of disease.

  8. Many people are having a misunderstanding that they mix global warming and green house effect together.Actually,green house effect is a good thing for us. It traps the sunlight in the atmosphere so that it minimizes the difference of the temperature between morning and night. But if too much, the temperature will be higher and higher. It will finally lead to global warming. As this big issue becomes more serious, it brings about a of crisis to human.

    Because of the rise of the temperature, the water level becomes higher. The ice in the southern and northern Antarctica is melting more quickly. In addition to the impact that the species in the area such as polar bear might lose their home (Losing home nearly = death. They will be hunted easily.), it fosters the sinking of the island.

    People always throw away rubbish and waste electricity. It all results in increasing of global warming impact.

    Feeling too hot, we would have more chances to turn on the air-conditioner. Air-conditioner will release carbon dioxide and harm the environment, causing a cycle of bad effects.

    Facing to this global crisis, we should help reduce the effect of global warming. As a human living on the planet, we can do a lot of things. We can reduce the use of electricity in order to minimize the power supply. ( Production of energy causes pollution) Moreover, we can take more public transportations than private vehicles. It can contribute to protection of air quality.

  9. I think that greenhouse effect and global warming are not the same thing.But they are in a relationship.The Earth always has some greenhouse gases to trap most of the heat and the infrared radiation which emitted by the sun, and the other heat and radiation will be reflected back to the space. If the Earth doesn't have greenhouse effect, the temperature of it is about -18 degree celsius.Greenhouse effect can keep the Earth in a average of 15 degree celsius so human can stay alive in the Earth.
    For the global warming,it happen when the greenhouse gases are increasing and the trap more heat and the Earth soon become warmer and warmer than before.As a result, we can see that the average temperature of the Earth is increasing since the industry era has begun.
    As we know the increasing of greenhouse gases such as carbon dioxide and methane can lead to global warming, so where are these gases produced from?
    The greenhouse gases are produced from the human beings.Burning fossil fuels and disforestation are the main 'resource' of greenhouse gases.In the process of refining chemical materials from fossil fuels, it produce many greenhouse gases and other toxic gases.It wouldn't be as serious as now if people don't clear the land(disforestation). But the worst situation have already occurred.
    The plants such as trees can aborb carbon dioxide when they are in a process of photosynthesis. But human cut down trees to make daily product such as paper and tissues when they are burning fossil fuels. The clearing of land contributes to the buildup of CO2 by reducing the rate at which the gas is removed from the atmosphere.
    As we can see disforestation and burning fossil fuels make a great contribution to the increasing of greenhouse gases,it proved that human beings is the main 'source'.
    Human seems to be very happy that fossil fuels and air-conditioners make their life become more comfortable,more convenient,they don't know they polluting the environmet and the human have to pay for it and they now have a boomerang caused by their actions to increasing greenhouse gases.
    Now, the eco-system is polluted seriouly by human. It seems none of human's business, but since the eco-system is polluted,it cause many environmental problems such as the great climate change and many disaster come up. Moreover,many people dead because of the disasters but there are still no solution or measures to solve this problem.
    Nowadays,environmental problems affect our daily life greatly so we should do some actions to support with the environmentally friendly and tried to overcome with the problems such as we can use four elements to represent the gernally actions:reuse,reduce,replace and recycle. It seems to be a little action, but when all human do it together,there will be a unexpected result.

  10. In recent year, lots of people think that green house effect and global warming are the same things. As both of them are also caused by increase temperature, but they are not the same things.
    The greenhouse effect is the name applied to the process, which causes the surface of the Earth to be warmer than it would have been in the absence of an atmosphere. And The greenhouse effect is important because if we have not the greenhouse effect, the Earth would not be warm enough for humans to live. But if the greenhouse effect becomes stronger, it could make the Earth warmer than usual. Even a little extra warming may cause problems for humans, plants, and animals.
    The global warming refers to the name given to an expected increase in the magnitude of the greenhouse effect, whereby the surface of the Earth will almost inevitably become hotter than it is now. When the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere. This is like when heat is trapped in a car. On a very hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows, but it can’t get back out. And also it is what the greenhouse effect does to the earth.
    Moreover, there has many things cause global warming. One thing that causes global warming is electrical pollution. Electricity causes pollution in many ways, some worse than others. And we are doing many things to try to stop global warming. One thing we are doing is carpooling. Carpooling is driving with someone to a place that you are both going to. This minimizes the amount of greenhouse gases put into the air by a car. We need to stop the global warming as soon as possible and save the earth.
