No, there were scientists:
Maslowski, Professor Peter Wadhams, Warwich Vincent James Hansen personally and NASA. In fact Wadhams stated this: The implication is that this is not a cycle, not just a fluctuation. The loss this year will precondition the ice for the same thing to happen again next year, only worse. There will be even more opening up, even more absorption and even more melting.
The 2013 prediction was not made by these scientists.
