Global warming is the rise in temperature of the earth's atmosphere. The earth is naturally warmed by rays from the sun which pass through the earth's atmosphere and are reflected back out to space again.
The 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 is bad. Water vapour, Carbon dioxide, Methane, Nitrous oxide, Ozone and Chlorofluorocarbons are all natural gases, but extra greenhouses gases can be made by humans from pollution. In addition, global sea levels could rise by more than 20 feet with the loss of shelf ice in Greenland and
Nowadays, there are many agencies which consider solving this big problem. Because, the Global Warming can be effect everybody who lives in the world.
