Global Warming

Global warming is the increase of earth’s average surface temperature due to effect of greenhouse gases. Earth’s climate is mostly influenced by the first 6 miles or so of the atmosphere which contains different fact gases. If the greenhouse gases like carbon dioxide, water vapor, CFC, nitrous oxide and methane increase in the atmosphere, they can entrap heat of the sun preventing from escaping much like the glass panels of a greenhouse. This process, known as greenhouse effect, increases the average temperature of the atmosphere resulting in natural disasters in the earth through climate change. The main culprit for temperature rising is carbon dioxide which is emitted by burning fossil fuels like coal, mineral oil and natural gas and due to deforestation. Fossil fuels are being burnt throughout the world to run buses and trucks, for electricity generation, in different manufacturing industries, to heat the house and so on which result in the total worldwide emission of about 22 billion tons of carbon dioxide to the atmosphere each year. Other gases are also being released in one way or other. Moreover, a large number of trees are being cut down or burnt in need of agriculture and habitat. All these are causing rise in the temperature of the atmosphere. As a result, polar ice caps are melting causing sea level to rise. A significant change is noticed in the climate of the earth resulting in frequent and untimely floods, cyclone, drought, tsunami etc. Rising sea level may flood the low lying coastal areas and change in land productivity on a large scale. It is undoubted that human beings are responsible for these natural dangers. Therefore, it is clear that if we are unjust to nature with our behavior and activities, nature will also take revenge upon us leading us towards various calamities.
