Climate Change

• Global Effects of Climate Change?


  Melting of glacial ice rises sea levels

  polar habitats will disappear

  hunting habitats altered

  increased risk of wildfires

  rise in temperatures mean reduced rainfall

  eg the Australian bush fires
• Human Causes of Global Climate Change?


  Cow dung and decaying landfill produce methane toxins

  which contribute to global warming

  deforestation causes CO2 levels to rise as no trees

  burning trees previously used as coolants in fridges
• Physical causes of global climate change?


  Variations in solar energy may affect global temperature

  Variations in earths orbit may affect

  Sulphur Dioxide gas and dust particles effect amount of solar energy reaching the earth

  Changes in ocean currents may affect
• Effects of Climate change


  increased temperatures cause ice caps to melt

  Melting ice causes sea levels to rise , this threatens coastal settlements

  increase in temperature causes water to expand which can cause flooding

  global warming can affect weather patterns leading to more droughts

  crop failures and problems with food supply
• Solutions to climate change


  co2 commissions rising sea levels means scientists need to monitor the rate of climate change

  countries find new types of energy eg biofuels

  industries develop and expand, finding things more substainable than fossil fuels eg wind and wave power

  developing countries reduce deforestation and increase afforestation
