DESCRIPTION:Observations give evidence that the Arctic sea ice is in decli
 ne. While some of the decline can be attributed to natural variability\, A
 rctic sea ice is a prominent indicator of Climate Change. Is it possible t
 o predict inter-annual variability of Arctic summer sea ice beyond the cli
 mate trend? Sources and limitations of sea ice predictability are discusse
 d. Arctic summer sea ice can be accurately predicted using melt pond fract
 ion in spring. This is due to a strong positive feedback mechanism: more p
 onds reduce the albedo\; a lower albedo causes more melting\; more melting
  increases pond fraction. The variability of Arctic sea ice during the las
 t 5 years is analyzed including previous predictions and how they performe
 d. What can we learn for sea ice modelling?
