             It is found that global warming, the rise in temperature of the earth's atmosphere, completely threat our life.  We have already known that the greenhouse gas emission, which is very popular phenomenon in the world, has perilous impact like making the weather get heater. Besides, the illegal logging done by irresponsible people also make the forests lose their function as the world’s lungs. Moreover, the use of fuel-powered vehicles producing more carbon dioxide on the air makes the ozon layer get thinner. Furthermore, the manufacture factories cause the smoke that makes the atmosphere worse and worse. It will be very dangerous if we let the rising temperature go on without making any evidence to overcome it.
            According to the wikipedia, Global warming is the term used to describe a gradual increase in the average temperature of the Earth's atmosphere and its oceans, a change that is believed to be permanently changing the Earth’s climate. It is such a kind of changing condition of global climate that cause many impacts in human being.  The climate change have a significant impact on water supplies in the next time due to the dry climate. The warm climate absolutely influences the circulation of the lives in the world and it is predicted that what will happen in the coming decade is worse than ever.
       There are some examples showing the perilous impacts of global warming. First, the water resources are getting less. Consequently, we must use the water sufficiently and we must not use it wastefully. Second, the lack of energy supply caused by the overuse of energy. Third, global warming also make the plants not able to grow well. The human health is also influenced by the heat climate; for example, the risk of illness and death caused by the extreme climate is increasing.

          According to the data above, we find that the history of the scientific discovery of climate change began in the early 19th century when ice ages  and other natural changes in paleoclimate  were first suspected and the natural greenhouse effect  first identified. In the late 19th century, scientists first argued that human emissions of greenhouse gases  could change the climate, but the calculations were disputed. Many other theories of climate change were advanced. In the 1960s, the warming effect of carbon dioxide gas became increasingly convincing, although some scientists also pointed out that human activities affect as well. During the 1970s, scientific opinion increasingly favored the warming viewpoint. By the 1990s, as a result of improving fidelity of computer models and observational work confirming the Milankovitch theory  of the ice ages, a consensus position formed: greenhouse gases were deeply involved in most climate changes, and human emissions were bringing serious global warming.
         In conclusion, global warming happens due to the activities that humans have done in many different ways, so that the climate change is affecting the planet and our communities. The impacts of the global warming itself are not little problems. We have to realize that the impacts will influence our coming lives. It can threat the human being in this planet. We must be aware of these serious consequences if it keeps going on. Therefore, we must overcome these perilous impacts by moving on and doing any evidence to prevent it before it gets poorer.
