The 'greenhouse effect' is a climate warming effect that results when the atmosphere traps heat radiating from Earth towards space. When solar radiation falls on the earth, it re-emits heat in the form of infra-red radiation. However, part of this reflected heat does not leave the Earth's atmosphere and is trapped by gases such as carbon dioxide, methane, etc. This increases the temperature of the Earth. Without these gases, the temperature of the Earth would be -18°C.
