It means: the National Climate Data Center says
- The combined global land and ocean surface temperature for July 2009 was the fifth warmest on record, at 0.57°C (1.03°F) above the 20th century average of 15.8°C (60.4°F).
- The global ocean surface temperature for July 2009 was the warmest on record, 0.59°C (1.06°F) above the 20th century average of 16.4°C (61.5°F). This broke the previous July record set in 1998. The July ocean surface temperature departure from the long-term average equals June 2009 value, which was also a record.
