Global warming is a big issue of the atmosphere on the earth which cause continuous rise in the surface temperature of the Earth. It has been estimated that in next 50 or 100 year the temperature of earth would be increased to a great level which would create big problem of living on earth. The highly known and most basic cause of increasing the Earth’s temperature is continuous rise in the atmospheric carbon dioxide.Rise in the carbon dioxide level is the use fossil fuels like coal and oil, deforestation (cut down of plants) by the human beings on Earth. Decreasing number of the plants on the earth increases the level of carbon dioxide, as plants are the main source of the using carbon dioxide released by the human being (as a by-product of respiration) and other means. Increasing level of Earth’s temperature creates lots of problems like sea level becomes hotter and higher, glaciers melt, flood, strong storms, lack of food, diseases, death, etc.
