Explanation:
Continuous increase in temperature of the earth is called global warming.
Global warming is one of the greatest challenges that our planet is facing as we have been facing the continuous rise in the average temperature of the Earth’s climate system.
It occurs as a result of an increased release of greenhouse gases in the atmosphere. These gases, like carbon dioxide, methane, and water vapor in the atmosphere, trap solar radiations released back by the Earth.
There are many reasons for it. One of them is increase in population. Increase in the number of vehicles is also one of the causes.
Pollution of air has also increased the global warming. Cutting trees, grazing the plants by animals increase the global warming.

Explanation:
Global warming is the latest alarm bell for earth’s environment. Global warming refers to the increase in average temperature of earth’s surface during the last century, from 1900-2000. Earth’s surface’s temperature has increased more than one degree Fahrenheit since 1900. Global warming is alarming because of its adverse effects on the ecological balance of earth. The resultant ecological imbalance, due to global warming, is the root cause of various natural calamities like floods, famines, etc. Also it is the root cause of various environmental threats like increase in sea level, glacier melting, changes in quantity and pattern of rainfall, heat waves, extreme seasons, etc. This is why global warming is the buzzword of almost all environmental talks, projects and discussions, etc.
Global warming is a threat to the very existence of life on earth. Not only human, but any other form of life, be it flora or fauna face a threat in the face of global warming. Hence, it has became the pungent need of the hour to root out the causes of this threating phenomenon.
The most evident causes of global warming are industrialisation, urbanisation, deforestation, sophisticated human lifestyle and related human activities. These human activities and trends have led to increased emission of greenhouse gases like carbon dioxide, methane, nitrous oxide, etc. These gases in turn has led to an increase in average temperature of earth’s surface, hence global warming history.
Greenhouse effect is a natural process wherein sunlight passes through atmosphere, warming earth’s surface. Then, the earth’s surface and water bodies release energy in form of heat or infrared radiations into atmosphere and maintains balance with the incoming energy. Greenhouse gases can absorb some of the infrared radiation. But increase in greenhouse gases has led to more absorbation of infrared radiation which in turn has led to the increase of earth’s surface temperature.
There is no doubt that the ever increasing phenomenon of global warming would lead to a total extinction of any form of life from earth’s face. Global warming deplets the ozone layer and might lead us to the doom’s day. It is a wake-up call for us to amend our ways of living to limit the use of products that contribute to the increase in global warming. For our sake and for existence of all life on our heavenly planet earth, it is the need of the hour that we make sincere efforts and attempts to contain the monster called ‘global warming’.
