GLOBAL WARMING The green house gas connection in the atmosphere has dramatically been increasing over the last 50 years. This has increased almost percent of the observed temperature. The largest contributing source of green house gases is the burning of fossil fuels like oil, gas, kerosene, etc. leading to the emission of carbon dioxide. Global warming refers to a gradual increase in the average temperature of the earth at the lower atmosphere because of the increase in green house gases since in the industrial revolution. When sunlight reaches earth surface some is absorbed and warms in the earth. Most of the rest IR radiated back to the atmosphere at a longer wave length than the light. Water vapour, carbon dioxide(CO2),methane(CH4),ozone(O3),nitrous oxide, sulphur hexafluoride, hydro fluorocarbons, per fluorocarbons, chlorofluorocarbons, etc. in the atmosphere which act like a green house around the earth absorb some of this longer wavelengths before any escaped back in to space. The absorption of this long wave radiant energy warms the atmosphere. This green house gases act like a mirror and reflect back to the earth a part of the heat radiation, which would otherwise be lost to space. The more the concentration of the green house gases, the more heat energy is being reflected back...
