Introduction to Global Warming

Global warming is the rise in temperature of the earth's atmosphere. Also it will increase if people still continue the same way. The earth is naturally warmed by rays from the sun which passes through the earth's atmosphere and is reflected back out to space again. So some global warming is good. But if extra greenhouse gases are made, the thermal blanket gets thicker and too much heat is kept in the earth's atmosphere. That's when global warming's bad.

Now I will mention the problems which are causes the global warming.The first problem is that gases are produced through activities which release carbon dioxide, methane, nitrous oxide and ozone. there is another problem which is smoke gas will cause the polution.

Finally, the global warming is very serious for us, so I devise everybody to care about it.
