Greenhouse Gases

All of these gases contribute to the greenhouse effect by re-radiating most of the heat energy which has been reflected off the Earth’s surface back towards Earth. Human activity releases huge amounts of greenhouse gases in the form of air pollution.

Water vapour

Water vapour

Water vapour is produced when water evaporates.
Under climate change, rising temperatures cause more water to evaporate, creating a positive feedback loop where water vapour intensifies global warming, causing even more water to evaporate.

Carbon dioxide

Carbon dioxide

Released from burning fossil fuels (coal, oil and natural gas).

Methane

Methane

Released from the burning of fossil fuels, and from agriculture practices like rice paddies and cattle farming.

Nitrous oxide

Nitrous oxide

Also known as 'laughing gas', used as an anaesthetic.
Released from fertilisers in agriculture.

CFCs

CFCs

Releases from aerosols, refrigerators and air conditioners.
