Today, we will focus on how global warming has come about. On the whole, all scientists subscribe to the same view that it is huge quantities of carbon dioxide that has resulted in this global warming. To make matters worse, the temperature of the earth tends to go up . Some scientists think this increase will cause the rise of the sea level , severe floods ,droughts or even the disappearance of species. However, other scientists are opposed to this view. They believe the rise will encourage a range of plants and animals. Nobody knows for sure what global warming will bring us. The problem is that the climate is going to keep on warming for decades or centuries even if we start reducing the amount of carbon dioxide now.
