The heating up of the earth surface due to trapping of infrared radiations reflected by earth's surface by CO2 layer in the atmosphere is called green house effect.
Some major green house gases and their sources:
An increase in average temperature of the earth's atmosphere due to green house effect which can have effects on climate and key life, support system of planet.
An increase in global temperature is also likely to increase the incidences of infections diseases like malaria, dengue, sleeping sickness and yellow fever.
Computer model predicts that during next 50 years the average temperature rise from 1.5 0 C to 3.5 0C.
Such a change ,which is very rapid by natural standards ,could have far reaching effects , especially at extreme levels .These could be in the form of
1) a rise in sea levels up-to 5 to 6 meters from the melting of ice cap and glaciers and the thermal expansions of sea water.
2) altered climate pattern altering ecosystems and
3) more extremes of weather .
Some major green house gases and their sources:
| Gas | Sources |
| Carbon Dioxide (CO2) | 1)Fossil fuel combination (coal,oil,natural gas) 2) Deforestation and land use changes |
| Methane (CH4) | 1) Enteric fermentation in cattle and insects. 2) Biomass burning and garbage land fills 3) Leakage of gases from coal mines and natural gas. 4) Rice paddies 5) Swamps and tundra |
| Chloro fluoro carbon (CFC'S) | 1) Plastic foams 2) Refrigeration and air-conditioning 3) Aerosols (spray propellants) CFC' 4) Industrial solvents |
| Nitrous oxide (N2O) | 1) Fertilizer use 2) Fossil fuel combustion 3) Biomass burning 4) Changing land use |
