Greenhouse gases
A concise illustrated collective description of greenhouse gases from the Energy Information Administration EIA, a statistical agency of the U.S. Department of Energy.

Fluorinated greenhouse gases
Hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulphur hexafluoride (SF6) are significant greenhouse gases that are by products of the electronics industry. The European Environment Agency provides figures, assessments and links to more detailed fact sheets.

Greenhouse gas data
Greenhouse gas data from the EIA listing emissions from transport, power generation as a result of coal gas and petroleum consumption

Animation of the greenhouse effect
An animation from the BBC to show how gases such as methane and carbon dioxide cause the greenhouse effect by increasing atmospheric temperature

The Carbon Cycle
The Met office offers a simple explanation of how the increased carbon dioxide from man-made emissions affects the way carbon is cycled on the planet.

Deforestation
Plants use carbon dioxide for photosynthesis. Vast rainforests act as "carbon sinks". Deforestation would destabilise greenhouse gas concentrations.

Methane greenhouse gas activity
Methane has 21 times the warming potential of carbon dioxide and is generated through anthropogenic activities such as landfill and livestock emissions. The Environment Agency has an entry for it in the Pollution inventory

Dinitrogen oxide greenhouse gas activity
Dinitrogen oxide is the third most significant greenhouse gas. The Environment Agency has an entry for it in the Pollution inventory
