It’s Getting Hot In Here

NOAA reported today that the combined global land and ocean surface temperature was the highest for any January on record. According to the NOAA National Climatic Data the most unusually warm conditions were in the mid- and high-latitude land areas of the Northern Hemisphere. The combined global land and ocean surface temperature was 1.53 degrees F (0.85 degrees C) warmer than the 20th century average of 53.6 degrees F (12.0 degrees C) for January based on preliminary data, surpassing the previous record set in 2002 at 1.28 degrees F (0.71 degrees C) above the average.

Last month’s record was greatly influenced by a record high land-surface temperature, the fourth warmest global ocean-surface temperature was in the 128-year series, and a moderate El Niño episode that began in September 2006. In the contiguous United States, the monthly mean temperature was near average in January.

The presence of El Niño, along with the continuing climate change trend, contributed to the record warm January. NOAA reported that the monthly mean temperatures more than 8 degrees F above average covered large parts of Eastern Europe and much of Russia, and temperatures more than 5 degrees F above average were widespread in Canada. The unusually warm conditions contributed to the 2nd lowest January snow cover extent on record for the Eurasian continent.
