Global warming

Global warming means the process in which the temp. of the earth rises up at an incredible (sometimes amazing speed) which directly affect in the livelihood of individual population. global warming is caused when pollution grows. When pollution increases  then the outer atmosphere of earth are covered by the harmful air. When the rays of sun enters inside our earth then these types of gases acts as a mirror which reflects down the rays that try to escape from our earth.
Finally due to these reasons the temperature of earth rises up which results in the natural calamities to cause in our world. Some of the ways that shows that global warming is increasing rapidly in our world is the sudden change in the temperature of our surrounding. that is sometimes very hot whereas sometimes very cold. Constant raining  in winter season and no rainfall in summer season can be taken as a methods to determine the increasing global warming in our world. So global warming has become a great challenge in our present world which must be stopped as soon as possible.
