lowest ever May Arctic ice extent
A weather driven ice free September is now possible in any given year. A climate driven ice free September is not likely until 2030 to 2050, and I would trend toward the later part of that period. As climate warms weather should become less predictable, a somewhat balanced system becomes disturbed and more chaotic until a new equilibrium is reached, which will be a long time coming. -- Carex on the Arctic Sea Ice Forum
