      A threat multiplier is defined as another agent that impacts a current situation, creating an additional set of problems while also making existing problems worse. Sometimes a seemingly innocent change in the biosphere ...
    • Biospheric Feedback Loops and Rapid Global Climate Change 

      Cairns, John (National Academy of Sciences, 2010)
      A positive feedback loop makes an existing process speed up while a negative feedback loop decreases the impact of an existing process. A source emits carbon dioxide and other greenhouse gases while a sink retain and stores. ...
    • Biospheric Health and Integrity: The Top Priority for Humankind 

      Cairns, John (National Academy of Sciences, 2009)
      All life on Earth depends on the biospheric life support system to provide both natural capital, or resources, and ecosystem services. Why, then, is the human economy, a subset of the biosphere, given the highest priority ...
