Where does each gas come from?
Carbon dioxide (CO2)
Natural
It is released through natural processes
Respiration
Volcano eruptions
Anthropogenic
It is released through human activities
Deforestation
Land use changes
Burning fossil fuels
Humans have increased atmospheric CO2 concentration by 47% since the Industrial Revolution began.
The most important long-lived "forcing" of climate change.
Water vapor
Natural
Increases as the Earth's atmosphere warms
It creates the possibility of clouds and precipitation
It acts as a feedback to the climate.
It makes some of the most important feedback mechanisms to the greenhouse effect
Methane
Natural
Agriculture
Rice cultivation
Decomposition of wastes in landfills
Anthropogenic
Manure management associated with domestic livestock
Ruminant digestion
Methane is a far more active greenhouse gas than carbon dioxide, but also one which is much less abundant in the atmosphere.
Chlorofluorocarbons (CFCs)
Largely regulated in production
Synthetic compounds entirely of industrial origin
Release to the atmosphere by international agreement for their ability to contribute to destruction of the ozone layer.
Nitrous oxide
Natural
Produced by soil cultivation practices
the use of commercial and organic fertilizers
Nitric acid production
Fossil fuel combustion
Biomass burning
