This is called the greenhouse effect. And, it is perfect. But what is a matter of great anxiety is the fact that the intensity of this warming is increasing. As a result, the world is getting warmer. One way to look at it could be to raise a question.
Scientists say no.
So this rise is man-made. Industries, automobiles, aviation and our use of utilities release a great amount of carbon dioxide and a few other gases known as the greenhouse gases and this has become a matter of major concern. Now if it is allowed to continue at the present rate, world climate would change as a result of the rise in the world temperature by 1.5 C to 4.5 C over the next 100 years. What follows then would be crop damage, rising sea level and flooding affecting millions of people and their property. This concerns all countries and all people.
