This is the type of variability that comes from natural interactions between the ocean and the atmosphere (i.e., that due to phenomena like the El - Nino / Southern Oscillation or perhaps the Atlantic Multidecadal Oscillation).

They found that between 5 % and 30 % of the Arctic sea ice decline from 1979 to 2010 could be attributed to the natural cycles of the Atlantic Multidecadal Oscillation (AMO) and Arctic Oscillation (AO), and even less can be attributed to natural cycles since 1953, since these natural cycles tend to average out over longer timeframes (as Vinnikov also found).
