First Half of 2010 is the Warmest on Record for the Globe

The first six months of 2010 were the warmest on record, according to a new analysis by the National Oceanic and Atmospheric Administration (NOAA). The agency's National Climatic Data Center (NCDC) found that the combined global land and ocean surface temperatures averaged 57.5°F for January through June, which is 1.22°F above the 20th-century average. For comparison, the second-warmest January-June on record was in 1998, when the average global temperature was 1.19°F above the 20th-century average. Temperatures on land were the second-warmest on record, falling behind 2007, while ocean surface temperatures were also the second-warmest on record, falling behind 1998. In addition, every month from March to June 2010 was the warmest on record for the globe. See the NOAA press release and the NCDC analysis.
