what is Global warming
The increase in the earth's average temperature is referred to as global warming. Gases in the earth's atmosphere such as methane and carbon dioxide trap heat and light from the sun. these gases are called greenhouse gases.
This trapped heat increase the overall temperature of the earth.
This process by which heat is absorbed by atmospheric greenhouse gases and re-emitted back towards earth is called the greenhouse effect. It is necessary for the survival of all life on our planet. Global warming happens because of increase in greenhouse effect, largely due to human activity like burning of fossil fuels and deforestation.
