The radiation (energy) comes from the Sun,
Passes through the atmosphere and reaches to surface of Earth
The surface reflects the radiation with different ratios according to pattern and shape of the land.
Reflected radiation is absorbed by the greenhouse gases, which consists mainly CO2, CH4, N2O, HFCs, PFCs and water vapor.
This natural event is called Greenhouse Effect.
If there wasn’t greenhouse effect, the surface temperature of Earth would be colder than the natural temperature, around –15 °C
Carbon dioxide (CO2). Mainly come from fossil fuels burning for energy production, heating, tranporting and industrial production.
Methane (CH4). Comes from decomposition of organic materials under the anaerobic conditions. Main source; Manure, Agricultural and Agro-industrial wastes and Landfill areas.
Nitrous Oxide (N2O), Comes from Exhaust gases, Fossil fuel burning and Organic materials.
Sulphur hexafluoride (SF6),
Water Valour (H2O)
The gasses which create greenhouse effect are accumulated at the atmosphere as a result of daily activities of human
That’s why the concentration of greenhouse gasses at the atmosphere have increased more than the natural concentration.
In parallel to the increase of the greenhouse gases, the average temperature of Earth surface have rose up.
This temperature rising called as Global Warming.
Today, average temperature increase reached over 2°C.
Climate changed naturally several times since the beginning of Earth.
But now, this change is totally different.
It has happened because of Human impact
Main reason of rapidly increasing the greenhouse gas emissions for last two centuries is due to the industrial revolution.
