   For sudden, read a couple of hundred years, and look at the end of the   
   last ice age, and the fact that the Gulf Stream got turned off for   
   about 1300 years at the end of the last ice - the Younger Dryas.

   That set in quite rapidly in some places - Greenland cooled off over a   
   period of three years.   
      
   The changes in climate would have been quite dramatic enough and quite   
   fast enough to rate as catastrophic - business as usual would not have   
   been an option.

   Think again, or think a bit harder.

   The flooding of the Black Sea, which happened at much the same time, did   
   have more to do with sea level rise. It seems to have been spread over a   
   couple of hundred years, and people would definitely have noticed.
