An Inconvenient Truth

Global Warming is caused by many things and every day scientists come out with a new one. The causes are divided into two groups, natural causes and man-made. One natural cause is the big release of methane gas in the Arctic. The other causes are the man-made causes which are the most important reason for this big issue such as using fossil fuels. These led to carbon dioxide emissions from trucks, carbon dioxide from airplanes, and carbon dioxide from buildings. We have to keep our sight clear and try to stop global warming from spreading. And we have to know how much loss global warming may cause to the world.
