4.13 Greenhouse gases

4.13 understand how human activities contribute to greenhouse gases.

The burning of fossil fuels results in more Carbon dioxide, and Nitrous oxide in the atmosphere which are greenhouse gases.

Farming cows causes a significant contribution of Methane from their digestion of crops (9% of the atmospheric gases)

Evapouration of water to form water vapour... Clouds are a significant contributor

Refrigeration/Solvents (CFC's) are associated with the absorption of UV light, and the breakdown of the Ozone layer
