Data and Map from NCDC/NOAA "State of the Climate" NCDC
Year-to-date (January–October, 2010)
The January–October 2010 map of temperature anomalies shows that anomalous warm temperatures were present over much of the world, with the exception of cooler-than-average conditions across the higher-latitude Southern oceans, the eastern equatorial and northern Pacific Ocean, parts of Argentina and Chile, central Russia, and Mongolia. The combined global average land and ocean surface temperature for the January–October period tied with 1998 as the warmest such period on record. This value is 0.63°C (1.13°F) above the 20th century average. Separately, the average worldwide land surface temperature ranked as the second warmest January–October on record, behind 2007. The worldwide average ocean surface temperature tied with 2003 also as the second warmest such period on record, behind 1998.
The Northern Hemisphere land surface temperature was the second warmest on record for January–October. The ocean temperature was also the second warmest such period on record. The Northern Hemisphere as a whole–land and ocean combined–had its warmest January–October on record.
In the Southern Hemisphere, both the land surface temperature and ocean surface temperature ranked as the fourth warmest January–October since records began in 1880. The Southern Hemisphere as a whole tied with 2002 and 2003 as the second warmest January–October on record.
- For January–October 2010, the global combined land and ocean surface temperature was 0.63°C (1.13°F) above the 20th century average of 14.1°C (57.4°F) and tied with 1998 as the warmest January–October period on record.
- The global average land surface temperature for the period January–October was the second warmest on record, behind 2007.
- The global average ocean surface temperature for the period January–October tied with 2003 as the second warmest on record, behind 1998
