Global Warming

Global warming is the big environmental issue we are facing today as a greatest challenge which we need to get it solved permanently. In fact, global warming is the continuous and steady process of increasing in the temperature of earth surface. It needs to be discussed widely by all countries worldwide to stop the effects of it. It has impacted the nature’s balance, biodiversity and climatic conditions of the earth over decades.

Green house gases like CO2, methane are the main reasons of increasing the global warming on the earth which directly impacts the rising sea levels, melting ice caps, glaciers, unexpected changing climate which represents life threats on the earth. According to the statistic, it has been estimated that earth temperature has increased to a great level since mid 20th century due to the increased atmospheric greenhouse gas concentrations globally because of the increased demand of the human living standard.

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.

It has been measured that year like 1983, 1987, 1988, 1989 and 1991 as the warmest six years of the past century. This increasing global warming calls the unexpected disasters on the earth like flood, cyclones, tsunami, drought, landslides, ice melting, lack of food, epidemic diseases, death etc thus causing imbalance to the nature’s phenomenon and indicating end of life existence on this planet.

Increasing global warming lead to the more water evaporation from earth into the atmosphere, which in turn become a greenhouse gas and again causes rise in the global warming. Other processes like burning of fossil fuels, use of fertilizers, rise in other gases like CFCs, tropospheric ozone and nitrous oxide are also the reasons of global warming. The ultimate causes of such reasons are the technological advancement, population explosion, increasing demand of industrial expansion, deforestation, priority towards urbanization, etc.

We are disturbing the natural processes through the deforestation and use of technological advancement like global carbon cycle, making hole in ozone layer, etc and allowing the UV rays to come on earth thus increasing global warming. Plants are the ultimate source of removing extra carbon dioxide from the air and making it in balance thus by just stopping the deforestation and enhancing people for more plantation we can get success of reducing the global warming to a great level. Controlling the population growth is also a great hand towards reducing the global warming.
