Almost A Record


by Turkana

National Climate Data Center:

The average global temperature (land and ocean surface combined) for last month was the 2nd warmest on record for March, while the average temperature for the contiguous U.S. was near average (ranking the 63rd warmest), according to an analysis by NOAA's National Climatic Data Center in Asheville, N.C....

The global surface (land and ocean surface) temperature was the 2nd warmest on record for March in the 129-year record, 1.28° F (0.71° C) above the 20th century mean of 54.9° F (12.7° C). The warmest March on record (+1.33° F/0.74° C) occurred in 2002.

The global land surface temperature was the warmest on record for March, 3.3° F (1.8° C) above the 20th century mean of 40.8° F (5.0° C). Temperatures more than 8° F above average covered much of the Asian continent. Two months after the greatest January snow cover extent on record on the Eurasian continent, the unusually warm temperatures led to rapid snow melt, and March snow cover extent on the Eurasian continent was the lowest on record.

Although the ocean surface average was only the 13th warmest on record, as the cooling influence of La Niña in the tropical Pacific continued, much warmer than average conditions across large parts of Eurasia helped push the global average to a near record high for March.

Northern Hemisphere snow cover extent was the fourth lowest on record for March, remaining consistent with boreal spring conditions of the past two decades, in which warming temperatures have contributed to anomalously low snow cover extent.
