EXAM PRACTICE

Explain two possible environmental consequences of global climate change. [3+3]
 

 
 

The consequences may be at any scale and there are many possible answers. 

In each case, award [1 mark] for identifying a valid consequence with a further [2 marks] for two distinct points in the explanation, one of which could be exemplification.

Possible consequences include:

  • rising sea levels [1 mark] due to thermal expansion [1 mark] floods lowlands [1 mark]
  • melting ice / Earth’s albedo reduced/increased intake of solar radiation / warms climate further
  • increased temperature of oceans / greater incidence of tropical storms / devastation caused by hurricane Sandy in Haiti, Cuba
  • melting ice releasing freshwater into North Atlantic / shuts down ocean / may lead to falling temperatures in Europe.

Other possibilities: extinctions, moving biomes, bleaching of coral reefs, desertification, etc.
