Global Warming refers to the gradual increase in the average temperature of the Earth’s surface and atmosphere due to the excessive accumulation of greenhouse gases in the environment.
It occurs when gases such as carbon dioxide (CO₂), methane, and nitrous oxide trap heat from the sun in the Earth’s atmosphere. This process is known as the greenhouse effect. As the concentration of these gases increases, more heat is trapped, leading to a rise in global temperatures.
One major cause of global warming is the burning of fossil fuels such as coal, petroleum, and natural gas. These fuels are widely used in industries, vehicles, and power plants, and their combustion releases large amounts of carbon dioxide into the atmosphere, contributing significantly to global warming.
