1. Causes of global climate change

Geographic inquiry: How natural and human processes affect the global energy balance

  • The atmospheric system, including the natural greenhouse effect and energy balance (incoming shortwave radiation and outgoing longwave radiation)
  • Changes in the global energy balance, and the role of feedback loops, resulting from:
    • solar radiation variations, including global dimming due to volcanic eruptions
    • terrestrial albedo changes and feedback loops
    • methane gas release and feedback loops
  • The enhanced greenhouse effect and international variations in greenhouse gas sources and emissions, in relation to economic development, globalization and trade
  • Synthesis, evaluation and skills opportunities: The complexity of the dynamic climate system and the spatial interactions of different processes and feedback mechanisms
