The process of global warming occurs when greenhouse gases, such as carbon dioxide and other pollutants, accumulate in the atmosphere and absorb sunlight and other solar rays which have been reflected off the Earth’s surface. Normally, these rays would escape into space, but the pollutants trap the heat, causing the planet to become warmer. This phenomenon is known as the greenhouse effect, and is the cause of global warming.

(a) Lightning

(b) Deforestation

(c) Burning of Fossil Fuels
