Global Warming

这是一篇关于Global Warming的思维导图,清晰地展示了全球变暖的三个主要方面：原因（Causes）、影响（Effects）和应对措施（Countermeasures）。

Global Warming

• Casuses
  • Greenhouse gas in the atmosphere (water vapor, carbon dioxide, methane, nitrous oxide and chlorofluorocarbons) keep some of the heat from escaping.
  • Human activities, like the burning of fossil fuels, have increased the amount of CO2 in the atmosphere by more than a third since the Industrial Revolution.
• Effects
  • oceans
    • Ice sheets are melting.
    • Sea levels riss.
    • Coastal areas were flooded.
  • weather
    • more extreme
      • more intense major storms, floods and heavy snowfall, but also longer and more frequent droughts.
  • food sources
    • Growing crops becomes more difficult.
    • The areas where plants and animals can live shift and water supplies are diminished.
  • health
    • increase the amount of smog
      • Exposure to higher levels of smog can cause health problems.
        • asthma
        • heart disease
        • lung cancer
• Countermeasures
  • Use renewable energy.
    • solar
    • wind
