Geography

• Climate change


  Changes in the long-term temperature, wind speeds and rainfall patterns which evidence suggests is caused by human activities
• Greenhouse effect


  Greenhouse gases trap solar radiation, preventing the escape of outgoing infrared radiation, causing the temperature of the atmosphere to increase and the earth's average temperature to increase, resulting in climate change as higher temperatures cause wind and rainfall patterns to change
• Greenhouse gases


  • Carbon dioxide
  • Nitrogen dioxide
  • Methane
• Increasing amounts of greenhouse gases in the atmosphere


  Due to human activity, e.g. deforestation, burning of tropical rainforests, burning fossil fuels to generate electricity
• Ways to combat climate change


  1. Encourage more people to use public transport

  2. Develop renewable sources of energy (wind farms, solar panels, hydroelectric power, tidal power)

  3. Introduce congestion charges

  4. Stop deforestation and plant more trees
• Carbon footprint


  Measure of the amount of carbon dioxide produced by a person, organisation or a country in a given time
• How to reduce your carbon footprint


  • Buy locally grown produce or grow your own food to reduce "food miles"
  • Walk or cycle short journeys, car share and use public transport
  • Holiday locally to reduce CO2 from long distance flights
