In other words, it is the gradual warming of the air which ultimately results in the gradual increase in the world temperature. In short, the rise in atmospheric temperature is known as the greenhouse effect. The carbon dioxide is primarily responsible for temperature rise in atmosphere. The carbon dioxide is given off when coal and oil are burnt. As a result, the ice covering the North and south poles is melting and may eventually lead to a rise in sea levels which can flood many areas of the world . Scientists have already given warning that some parts of coastal countries including Bangladesh may go under water due to greenhouse effect. The total area of deserts is increasing every year .
