At a period in time when the arctic should be at its coldest, it is currently an astonishing 36% warmer. Usually during the winter time temperatures in the arctic drop and the sea ice starts to thicken. If the ice cannot form as it should during these winter months it will greatly affect the animals who call the arctic home. From polar bears that rely on the ice as hunting grounds, to the seals using it as pupping grounds to give birth.
The effects this could have on the planet are unknown since this is something we have yet to experience in our lifetime. They could be huge not only to the Arctic but to the entire planet.
