on .


GLOBAL TEMPERATURE: Data confirms another very hot December and on going global warming. The graph below is clear. For more than five years monthly temperature have been higher than the historical average. And December 2017 confirms the trend, being the third warmest December on record.

 
More precisely, according to the NOAA Climate National Climate Data Center,  the combined global average temperature over land and ocean surfaces for December 2017 was 0.80°C (1.44°F) above the 20th century average of 12.2°C (54.0°F)—tying with 2016 as the third highest December global temperature since records began in 1880. The last five years (2013–2017) are among the ten warmest Decembers on record. December 2017 also marks the 33rd consecutive December (since 1985) and the 396th consecutive month with temperatures at least nominally above the 20th century average.
 
 
Global temperature in December 2017 (land surface): 1.45°C (2.61°F) above the 20th century average
 
Global land surface temperature for December 2017 was 1.45°C (2.61°F) above the 20th century average of 3.7°C (38.7°F). During December 2017, the most notable temperature departures from average occurred across the Northern Hemisphere land. Western Canada, Alaska, eastern Europe, and western Russia had temperature departures from average that were +4.0°C (+7.2°F) or greater. Cooler-than-average conditions affected parts of western Europe during December 2017, in particular in Spain and Portugal. December 2017 was warmer-than-average for Australia. Warmer-than-average conditions plagued much of New Zealand during December 2017.
 
 
Global temperature in December 2017 (sea surface): 0.56°C (1.01°F) above the 20th century average
 
The December 2017 global oceans surface temperature was 0.56°C (1.01°F) above the 20th century average of 15.7°C (60.4°F) and the sixth highest December temperature in the 138-year record.
