Heat in summer can be troublesome. We resort to fans or air conditioners to cool us down. However, when the season changes, we often forget about the inconvenience by heat. Our planet, however, is facing a far larger problem. The fact that our planet is slowly heating up over the years has been ringing alarm bells in the science fraternity for a long time now.
The process of the earth’s warming up and rise in temperature is known as global warming. This happens when there is an increase in the production of gases like carbon dioxide, water vapour, nitrous oxide and methane, which are known as greenhouse gases. These greenhouse gases trap heat and light from the sun in the earth’s atmosphere. This trapped heat, in turn, increases the temperature and causes global warming.
It is matter of great concern that since the beginning of the 20th century the average temperatures of the earth have risen by 0.8 degrees Celsius. Global warming hurts people, animals and plants. In fact, many organisms cannot take the change; and therefore, they die out.
