What is global warming? Name the gas whose increasing percentage in air is leading to global warming. State a harmful effect which can be caused by global warming.

Global warming is the rise in the temperature of the earth's atmosphere caused by the excessive amount of carbon dioxide in the air. Due to the rise in the temperature of the atmosphere, the ice in polar regions will melt very fast, producing a lot of water. The burning of fuels releases carbon dioxide in the air in the environment.

An increased percentage of carbon dioxide in the air is causing global warming. Carbon dioxide gas in the air trap sun’s heat rays by producing the greenhouse effect.

The rise in water may cause a rise in the sea level leading to floods in coastal areas. The low-lying areas may be completely submerged underwater leading to loss of life and property.
