What is the greenhouse effect?
Greenhouse effect refers to the process whereby radiation from the atmosphere of the planet warms the planet’s surface to a temperature above that which would prevail in the absence of that atmosphere.
To simplify, here is the step-by-step process of the greenhouse effect.
1: Some of the solar radiation hit the Earth’s atmosphere
2: The rest is absorbed by the land and the oceans, which heat up the Earth
2: The heat from the Earth radiates then towards the space
3: Some of this heat is trapped by greenhouse gases in the atmosphere, keeping the Earth warm enough to sustain life
4: Through human activities such as burning fossil fuels and land clearing extra heat is produced which causes the Earth’s temperature to increase
