The overall warming of the planet, which is happening at a faster pace in the Arctic, has caused steady declines in both the max and min over recent decades (as well as an overall thinning of the ice), ranging from 10 to 15 percent per decade depending on the season. This sea ice retreat has major implications for regional wildlife, which can depend on the sea ice for hunting food; the livelihoods of indigenous cultures; and commerce, including oil exploration and shipping.
