What is the Cause?

 
 
 
 
 
Global warming is caused by increases in levels of greenhouse gases attributable to human activities.

Carbon dioxide is the main contributor responsible for 80% of emissions from industrialised countries. The gas is released into the atmosphere primarily from burning fossil fuels: oil, petrol and natural gas. A growing population coupled with increasing demands on transport and energy, has led to emissions increasing at dramatic rates.

Other greenhouse gases which arise from a range of industrial and agricultural sources are:

  • Methane
  • Nitrous oxide
  • Hydrofluorocarbons (HFCs)
  • Perfluorocarbons (PFCs)
  • Sulphur Hexafluoride (SF6)

Combined, these greenhouse gases absorb infrared radiation in the atmosphere and thus change the dynamic balance between energy arriving from the sun and energy escaping.
