During the winters of 1988-1996, strong winter winds pushed most of the older ice out of the Arctic, where it melted in the North Atlantic.
Those winds have changed in recent years, and now the amount of older ice has greatly increased since 2010.
Next summer will not see a big melt, because the Beaufort Sea is full of very thick, old ice.
