Global Warming: Global Warning Taneja Savita, Head Department of Education, Institute of Higher Education, Ghaziabad, UP, India. Abstract The sun energy is emitted as heat radiations. Some of these are absorbed and retained by the earth's surface. Then again some of the absorbed heat is reradiated by the earth into the atmosphere. There is an energy balance between the heat energy reaching the earth and the heat energy i.e. radiated into the space. This energy balance determined the earth's surface temperature. Excess accumulation of some gases like carbon dioxide, methane, chlorofluoro carbons(CFS). Ozone and water vapour are responsible for increasing heat on the earth. These gases are known as green house gases. These gases trap the earth heat and causes global warming. The problem of Global Warming is mainly generated by energy production and by the Chloroflourocarbongases, Deforestration & agriculture. Global warming create a some serious problems like green house effect, acid rain, rise of sea level, melting glacier, depletion of ozone layer. Top Key words Global Warming, Green House, Energy.
