The Green House Effect
The greenhouse effect is a natural process that warms the Earth’s surface. When the sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.
Greenhouse gases include water vapour, carbon dioxide, methane, ozone and some artificial chemicals such as chlorofluorocarbons (CFCs).
The absorbed energy warms the atmosphere and the surface of the Earth. This process maintains the Earth’s temperature at around 33 degrees Celsius warmer than it would otherwise be, allowing life on Earth to exist.
But with the effect of human activities especially burning of fossil fuel has lead to increase in Carbon dioxide which help in storing more heat that is being trapped in the ozone layer and released into the earth atmosphere leading to drastic changes in temperature which in turn lead to extreme weather change on earth like drought, melting of the Antarctic ad glaciers leading to rising sea level among other effects.
