.  To try to determine the potential magnitude of future global warming, scientists  estimate something called "climate sensitivity".  Which of the following statements is INCORRECT concerning "climate sensitivity".
   a.  it is typically the amount of warming in degrees Celsius expected to occur in     
                 response to a doubling of atmospheric CO2 levels from their preindustrial           
                 level.
            b.  when scientists say equilibrium climate sensitivity, it means the full warming   
                 response may not be realized for many decades due to the sluggishness of
                 ocean warming
            c.  preindustrial atmospheric  levels of CO2 were roughly 380 ppm (parts per
                 million) by volume- similar to the 2008 value of 386 ppm
            d.  at current rates of fossil fuel burning the doubling of CO2 levels is expected to
                  occur around 2050 or so, however resulting warming may not be fully experienced              until at least 2100.
