GLOBAL WARMING!!

Global warming is a serious problem because by global temperature rises, glacier(氷河) began to melt and surface of seawater rise. If this phenomenon occered, our lands will sink in the sea. It's so dreadful. Also, heavy extraordinary weather(大規模な異常気象), like floods, hurricane and so on, increase. Moreover, it causes big extinction(絶滅) of a lot of creatures like mammal, reptile, fishes and so on. Really every creatures will do. Like this, it effects temperature and ecosystem of around the world. Today, average temperature is rising from 1.1℃ to 6.4℃ from 1990. It's very abnormal to compare the past.

One solition to the problem of global warming is to reduce carbon dioxide. If you reduse it, global temperature dosen't rise. To reduse carbon dioxide, we need a lot of effort. How can you reduse it? One answer is we increase afforestation(植林), because trees emit oxygen and discharge carbon dioxide. Another one we should change air conditioner's temperature of our houses and companies. In summer, we should rise it and, in winter, we shooud lower it in Japan. Because it connects a decrease of global warming. In now society, it's difficult to reduse carbon dioxide, but it we have a lot of effort, we may be change this phenomenon.
