The temperature in the North Pole is 10degC higher than it usually is for this time of year; it was 5 degC on Wednesday morning (local time).
Storms over Iceland and Greenland, which are fairly common in winter, are pushing warmer air to the Arctic, Discovery News reports.
Though fluctuations in temperature are not uncommon in the Arctic region, a 10 degC shift is very notable. There have reportedly only been three other times since 1948 that temperatures in the North Pole have hit or risen above freezing in December, Time magazine reports.
Sea ice formations could be impacted by these high temperatures, which are already at historic lows.
