"Temperatures in the Arctic have hit more than 36 degrees Fahrenheit above normal as polar night bears down on the region.
In parts of Arctic Russia, experts say the anomalies even went beyond 40 degrees.
The shocking temperates come as the earth is on track for its warmest year on record after October temperatures equaled the third-warmest for the month ever, a U.S. government agency said.
Experts are baffled by the exceedingly high temperatures that are now occurring during a time that brings long periods of darkness, and usually, frigid temperatures.
Though October typically marks the start of a refreezing period, when the ice cover grows thicker and stronger following the summer melt, sea ice in the Arctic has hit a new low.
Data from Climate Reanalyzer shows how temperatures today have climbed upwards of 36 degrees Fahrenheit above the daily average.
In a provisional statement released this week, from the World Meteorological Organization on the status of this year's global climate, scientists predicted that 2016 will be the hottest year on record.
And, the data shows few areas have been hit as hard as the Arctic.
'In parts of Arctic Russia, temperatures were 6°C to 7°C [42.8-44.7°F] above the long-term average,' said Petteri Taalas, WMO Secretary-General."
