New data from NASA and the National Oceanic and Atmospheric Administration suggest that January of 2016 was, for the globe, a truly extraordinary month. Coming off the hottest year ever recorded (2015), January saw the greatest departure from average of any month on record, according to data provided by NASA.
But the record breaking heat wasn't uniformly distributed - it was particularly pronounced at the top of the world, showing temperature anomalies above 4 degrees Celsius (7.2 degrees Fahrenheit) higher than the 1951 to 1980 average in this region.
Indeed, NASA provides a "zonal mean" temperature map, which shows how the temperature departures from average change based on one's latitude location on the Earth. Things get especially warm, relative to what the Earth is used to, as you enter the very high latitudes.
