    Which of the following examples will result in positive feedback?
    • A. 

      Greater snow cover during climatic cooling reduces the activity of carbon dioxide sinks such as photosynthesis and formation of carbonate rocks, thus causing carbon dioxide to build up in the atmosphere

    • B. 

      Warming of the climate increases evaporation in the oceans, leading to greater cloud cover such that more solar radiation is reflected back into space.

    • C. 

      An increase in plant activity during global warming results in more carbon dioxide being removed from the atmosphere

    • D. 

      Climate cooling increases the snow cover on land, thus increasing global albedo and causing more solar radiation to be reflected back into space

  • 13.
