What's global warming?


Global warming is the increase in the average temperature of the Earth. It has begin since the mid-20th century. Now, global warming is the hottest issue of the world. Everybody speaks about global warming. The earth's temperature increases every year. I believe that everybody can feel it. The increasing temperatures make ice on the north and south hemisphere melt. Because of that, the sea levels rise, and our lands begin to sink. And, it will become the beginning of doomsday. So, what are you waiting for? Let's save our world, begin from now!
