- The Causes of Climate Change
- changing concentrations of greenhouse gases e.g. carbon dioxide, methane and nitrous oxide
- allow sunlight to pass through the earth's atmosphere but trap the heat that is radiated back towards space
- without them the Earth would be minus 18 degrees celcius
- external forcing
- the amount of sunlight reaching Earth is reduced or increased because of changes in the sun's activity/earth's distance from the sun
- changing concentrations of greenhouse gases e.g. carbon dioxide, methane and nitrous oxide
