Global warming is associated with the greenhouse effect that is produced when the Earth's surface and atmosphere absorb solar energy and reradiates the energy back into space. A portion of the absorbed energy is emitted by land and oceans, absorbed by the Earth's atmosphere, and reradiated back to the Earth
Greenhouse gases such as CO2, methane, etc. are gases that absorb the heat of the sun and then emit it back to the Earth's surface. Thus, these gases prevent a part of the heat rays from escaping into the atmosphere. This cycle is repeated several times to maintain the Earth's temperature to an optimum temperature. Therefore, upto a normal level, greenhouse gases help in maintaining the temperature on the Earth. However, the concentration of these gases has increased because of increased industrialization, which has lead to the heating up of the Earth's surface resulting in climatic changes. During the last century, the temperature of the Earth has increased by 0.6°C. This has lead to global warming.
