Nenana Ice Classic sets new record for latest breakup of the ice since the Classic began in 1917. This should not surprise as the interior of Alaska continues to be cold in 2013. 
The 2013 Jackpot was $318, 500.00
The Tanana River ice officially broke up on
May 20th at 2:41 pm Alaska Standard Time
The latest time on record the ice has ever gone out.
Congratulations to the winners!!!

Somehow it seems fitting that the pot for the new record break up time was won by people named SNOW.
Willis has pointed out that the breakup dates coincide with the PDO variations. 
There
 is no correlation with CO2 as the breakup dates have not gotten 
progressively earlier as would be expected in a world warmed by 
increasing amounts of CO2 in the atmosphere. We see an oscillation which
 just proves what we already know: climate changes continuously. And it 
does so in accordance with the PDO signal - the distribution of warmth 
in the waters of the Pacific Ocean which is currently in its cold phase.
 
The
 world was warming in the periods 1910-1940s and again from the 
mid-1970s to the late 1990s so we should not be surprised that the 
earliest breakup dates fall within the warming periods. 
The PDO is now in its cold phase which helps to explain the record delay in ice breakup in 2013.
