By Chris Dolce for WEATHER.COM
The winter of 2014-15 was the warmest on record worldwide, according to the state of the climate report released by the National Oceanic Atmospheric Administration (NOAA) on Wednesday.
NOAA says that December through February – for meteorological record-keeping purposes, winter is defined as those three months in the Northern Hemisphere – was 1.42 degrees Fahrenheit above the 20th-century average for all land and ocean areas. This tops the previous warmest winter of 2007 by 0.05 degrees Fahrenheit. Global temperature records are available for the period 1880-2015.
Individually, here is how each month ranked for the earth:
December 2014: Warmest on record.
January 2015: Second warmest on record.
February 2015: Second warmest on record.
Though it was a cold winter overall in eastern North America, including the United States, the Northern Hemisphere also saw its warmest winter on record. This was due to widespread above-average temperatures in western North America, Europe and Asia. NOAA says that record warmth was observed in the western United States, portions of central Siberia and eastern Mongolia.
