- Main Greenhouse Gases
- CO2(carbon dioxide)
- CO2 is the most significant greenhouse gas
- Carbon Dioxide accounts for 60% of the enhanced greenhouse effect
- EXAMPLES
- deforestation
- CH4 (methane, a hydrocarbon gas)
- accounts for 15% of the enhanced greenhouse effect
- the amount of methane in the atmosphere is quite small
- methane is 25 times more efficient at trapping radiation than Carbon Dioxide
- EXAMPLES
- landfill sites
- livestock
- rice cultivation
- decay of organic matter/waste
- thawing of permafrost
- Halocarbons
- mainly CFCs (chlorofluorocarbons)
- the only human made greenhouse gas
- only makes up a tiny proportion of all greenhouse gases
- can be 15000 times more efficient at trapping radiation than CO2
- they count for 15% of the greenhouse effect
- EXAMPLES
- air-conditioning
- refridgerators
- aerosols
- foam packaging
- Nitrous oxide
- naturally occurs in the Earths atmosphere as a part of the nitrogen cycle
- 250 times more efficient than CO2 at trapping radiation
- acouts for 6% of the enhanced greenhouse effect
- nitrous oxide molecules in the atmosphere have long life spans
- about 120 years before they are removed in a “sink” or destroyed as a result of chemical reactions
- EXAMPLES
- agricultural fertilizers
- car exhausts
- CO2(carbon dioxide)
