NOAA: Global Temperature Seventh Warmest for Spring, Eighth Warmest for May
June 13, 2008
The combined average global land and ocean surface temperatures for spring (March-May) ranked seventh warmest, while May was the eighth warmest since worldwide records began in 1880 according to an analysis by NOAA’s National Climatic Data Center in Asheville, N.C.
Spring (March-May) Highlights
- The combined global land and ocean surface temperature for spring 2008 was 0.94 degrees F above the 20th century mean of 56.7 degrees F and ranked seventh warmest based on the 1880-2008 record.
- The global land surface temperature for spring was 1.87 degrees F above the 20th century mean of 46.4 degrees F and tied with 2000 as third warmest.
- The global ocean surface temperature for spring was 0.59 degrees F above the 20th century mean of 61.0 degrees F and ranked 10th warmest.
May Highlights
- For May 2008, the combined global land and ocean surface temperature was 0.81 degrees F above the 20th century mean of 58.6 degrees F and ranked eighth warmest.
- The global land surface temperature for May was 1.26 degrees F above the 20th century mean of 52.0 degrees F and ranked seventh warmest.
- The global ocean surface temperature for May was 0.65 degrees F above the 20th century mean of 61.3 degrees F and ranked 10th warmest.
Other Highlights
- The extent of spring 2008 snow cover over Eurasia was the lowest on record for any spring in the 42-year historical satellite record. Conversely, North American snow cover extent was slightly above average. For the Northern Hemisphere, spring 2008 was the third least extensive spring snow cover.
- Continued weakening of La Niña, the cold phase of the El Niño-Southern Oscillation (ENSO), occurred during May. The ENSO conditions are expected to trend toward neutral conditions during the next two months.
