Global Warming


Global Warming

The sun’s radiation comes in a form of light waves which passes through the atmosphere, and then some of the radiation which is absorbed and warms the earth is radiated back to space in a form of infrared waves. Some of this out going infrared radiation is trapped by the earth’s atmosphere and warms it, keeps it relatively constant, livable and that keeps the temperature of the earth in a certain balance. The problem is the atmosphere layer has become thicker by the global warming pollution. That means that more of the out going infrared rays is trapped and so the atmosphere heats up and that’s global warming. The most dangerous affect of global warming is the extinction of many species like polar bears and other animals. Also, it affects the near future like water will come less and many lands will sink.
