  Hey rachelbadu,
  
  No i have never seen an iceberg break off and fall into the water in real life. If you do want to see it then there was an episode of Frozen planet where they showed it – it was absolutely amazing.
  
  I couldn’t give you an exact answer but not very long! 50 degrees is really high, especially considering it is usually more like -50 degrees down there! I would expect it to be all gone within a year but cant be more precise than that I’m afraid.
