  • Climate Change - Human Factors
    • Burning Fossil Fuels
      • Burning fuels releases harmful gases such as Sulphur Dioxide
      • One third of CO2 emissions comes from burning coal.
      • If the new coal plants that are being proposed are built, carbon emissions from coal are expected to rise 60 per cent by 2030
    • Increased output of gases
      • Nitrous Oxide
        • Vehicle exhausts are the main cause of Nitrous Oxide.
        • The impact of 1 pound of N2O on warming the atmosphere is over 300 times that of 1 pound of carbon dioxide.
        • It is 200 to 300 times more effective in trapping heat than carbon dioxide.
      • Methane
        • Methane produces 21 times as much warming as CO2.
        • Methane remains in the atmosphere for 11-12 years.
        • Since the Industrial Revolution, the level of Methane in the atmosphere has increased by about two and a half times.
    • Deforestation
      • When forests are burned, the carbon dioxide that is stored in the trees  is released back into the atmosphere, increasing the amount of carbon dioxide and other greenhouse gases
      • It is estimated that more than 1.5 billion tons of carbon dioxide is released to the atmosphere due to deforestation.
      • Over 30 million acres of forests and woodlands are lost every year due to deforestation
