Global warming is a hot topic nowadays worldwide. It is being discussed in every place within society. It is discussed in the scientific community. It is discussed among politicians. It is discussed at faculties, collages and among the folk. What is so important within the term heating? Global warming is a very important term because it’s connected with human survival on this earth. Everybody desires to understand, what is global warming? How global warming is happening? Causes for global warming? Impact of global warming worldwide on human life? Way to tackle global warming issues? We will seek answers, any or all on top of queries, in the brief discussion here.


    Global warming is a process of gradual increase in the temperature of the earth. Global warming is caused due to greenhouse gases in the atmosphere. The greenhouse effect is increasing due to the presence of greenhouse gases in the atmosphere. Greenhouse gases are:

    Carbon dioxide (CO2)

    Nitrous oxide(N2O)



    Water vapour

    These greenhouse gases form a protecting layer around the earth. When the suns infrared radiation reaches the earth, some of it is reflected back into space. However, some infrared radiation and lightweight energy are absorbed and entrapped by greenhouse gases. This entrapped radiation increase the earth’s temperature. As the number of greenhouse gases increasing within the atmosphere, radiation absorption is also increasing and ultimately rise of earth temperature.


    Greenhouse gases are a prime reason, to increase earth temperature.   Everyman and animal on the earth are contributing to increase greenhouse gases.  Large amounts of greenhouse gases into the atmosphere are due to the following activities:

    Industrial Development:

    Industrial development is quickly happening within the whole world. Every country is within the race of commercial development. Industrial units are producing a vast quantity of CO2 and obnoxious gases, which are the most contributor greenhouse gases within the atmosphere.

    fossil fuel use:

    We area unit victimisation fuel, like fossil fuel oil, coal, and fossil fuel copiously within the name of luxury and industrial growth. We should cut back the employment of fuel, in order to scale back the assembly of CO2. Renewable sources of energy like solar, wind and atomic, to be used for transportation and power generation. Vehicular transportation and power generation are the 2 main sectors that produce the major amount of greenhouse gases. They use a vast quantity of fuel.

    Use of luxury Items:

    Man has created air conditioners and refrigerators for comfort cooling, where chlorofluorocarbon (CFC) gases are in wide use. The leakage of CFC gases from air conditioners and refrigerators are a major contributor to greenhouse gases.CFC gases conjointly do breakage in the ozonosphere, resulting in an increase in earth temperature.


    Urbanization is the result of overpopulation. Cutting of trees and plants are being done to construct residential buildings and to make road infrastructure. It will increase the additional demand for water, sanitation and food. This is altering the natural rainwater cycle and causes erratic rainfall.

    Construction of dams:

    Dams are being constructed on flowing rivers, to make a reservoir for the storage of rainwater.  This vast water storage is employed for, agricultural farming, domestic use and power generation. However, deforestation is done to construct dams. Deforestation is inflicting ecological imbalance, resulting in erratic rainfall and the rise of earth temperature.

    Cattle rearing:

    We rear animals like cows, buffaloes, goats, and sheep for the production of meat and dairy products for consumption. Animals are feed on vegetation for their rearing. During digestion of coarse vegetation material in the stomach of animals, microbes referred to as methanogens, facilitate animals to digest food and produce a by-product as methane gas. Livestock is that the third-largest producer of methane gas in the atmosphere. It causes atmospheric warming phenomenon and ultimately heating.


    Volcanic Eruption

    Volcanic eruption causes unleash of a big quantity of CO2 within the atmosphere. This CO2 within the atmosphere causes global warming.

    Forest Fires

    Due to forest fires, the natural rainwater cycle gets disrupted. Forest fire emits waste product gases as CO2 within the atmosphere, causing heating. Water vapour is another gas gift within the atmosphere. The ocean is that the main source of water vapour generation. Excess water vapour within the atmosphere absorbs and retain additional suns radiation and inflicting heating.
