The Earth’s climate is driven by a continuous flow of energy from the sun.
Energy in the form of heat, from the sun, passes through the Earth’s atmosphere and warms the Earth’s surface.
As the temperature increases, the Earth sends heat energy (infrared radiation) back into the atmosphere.
Some of this heat is absorbed by gases in the atmosphere, such as carbon dioxide (CO2) , water vapour, methane, nitrous oxide, ozone and halocarbons.
