Global Highlights
The combined global land and ocean surface temperature was the sixth warmest on record in February, but a record warm January helped push the winter (December-February) to its highest value since records began in 1880 (1.30 degrees F/0.72 degrees C above the 20th century mean). El Niño conditions contributed to the season’s record warmth, but the episode rapidly weakened in February, as ocean temperatures in the central equatorial Pacific cooled more than 0.5 degrees F/0.3 degrees C and were near average for the month.
Separately, the global December-February land-surface temperature was the warmest on record, while the ocean-surface temperature tied for second warmest in the 128-year period of record, approximately 0.1 degree F (0.06 degrees C) cooler than the record established during the very strong El Niño episode of 1997-1998.
During the past century, global surface temperatures have increased at a rate near 0.11 degrees F (0.06 degrees C) per decade, but the rate of increase has been three times larger since 1976, or 0.32 degrees F (0.18 degrees C) per decade, with some of the largest temperature increases occurring in the high latitudes of the Northern Hemisphere.
