Global warming is the continuous rise in warming of the earth?s surface due to the increased level of carbon dioxide gas in the environment. Global warming has become a big issue which need to be solved by the positive initiation of countries all over the world. As gradual increase in the earth temperature calls various threats as well as makes the existence of life hard on this planet. It enhances the gradual and permanent changes in the earth?s climate and thus affecting the nature?s balance.
Rise in the CO2 level on the earth impacts the human life to a great level through continued heat waves, sudden occurrence of strong storms, unpredictable and unexpected cyclone, damage to ozone layer, floods, heavy rain, drought, lack of food, diseases, death etc. It has been researched that increasing emissions of CO2 in the atmosphere is because of the nonstop burning of fossil fuels, usage of fertilizers, cutting forests, extra use of electricity, gases used in refrigerator etc. According to the statistics, it has been noted that by 2020 global warming may boom its bad effects if it is not taken under control as CO2 emissions are increasing continuously.
The increasing level of CO2 causes greenhouse effect on the earth in which all the greenhouse gases (water vapour, CO2, methane, ozone) absorbs thermal radiation, which in turn re-radiated to all directions and come back to earth surface causing increase in the temperature of earth surface and lead to global warming.
In order to stop the life threatening effects of the global warming, we should take a permanent break from all the bad habits causing increase in the CO2 level and other green house gases leading to the green house effect and then earth surface warming. We should stop deforestation, lessen the use of electricity, stop the burning of wood, etc.
