New July Record for Global Ocean Temperatures
Global ocean surface temperatures for July 2009 were the warmest on record for all the months of July going back to 1880, according to the National Climatic Data Center (NCDC).

For the record, El Nino conditions (warming of the equatorial Pacific surface waters) were starting during the month of July, but it was still a weak El Nino.

According to the NCDC, global ocean temperatures ran 0.59 C or 1.06 F above the 20th century average and broke the old record, which was set back in 1998.

Very strange kind of cooling.

NOAA - National Oceanic and Atmospheric Administration - NOAA: Warmest Global Ocean Surface Temperatures on Record for July

The planet’s ocean surface temperature was the warmest on record for July, breaking the previous high mark established in 1998 according to an analysis by NOAA’s National Climatic Data Center in Asheville, N.C. The combined average global land and ocean surface temperature for July 2009 ranked fifth-warmest since world-wide records began in 1880.

Global Climate Statistics
The combined global land and ocean surface temperature for July 2009 was the fifth warmest on record, at 1.03 degrees F (0.57 degree C) above the 20th century average of 60.4 degrees F (15.8 degrees C).
The global ocean surface temperature for July 2009 was the warmest on record, 1.06 degrees F (0.59 degree C) above the 20th century average of 61.5 degrees F (16.4 degrees C). This broke the previous July record set in 1998. The July ocean surface temperature departure of 1.06 degrees F from the long-term average equals last month’s value, which was also a record.
The global land surface temperature for July 2009 was 0.92 degree F (0.51 degree C) above the 20th century average of 57.8 degrees F (14.3 degree C), and tied with 2003 as the ninth-warmest July on record.
 
It makes me hot when you post those stats like that. There's just something about graphs and charts that do it for me.
 
What the scientists have to say.

Recent observations show that greenhouse gas emissions and many
aspects of the climate are changing near the upper boundary of the IPCC
range of projections. Many key climate indicators are already moving
beyond the patterns of natural variability within which contemporary
society and economy have developed and thrived. These indicators
include global mean surface temperature, sea-level rise, global ocean
temperature, Arctic sea ice extent, ocean acidification, and extreme
climatic events. With unabated emissions, many trends in climate will
likely accelerate, leading to an increasing risk of abrupt or irreversible
climatic shifts.
 
University of Colorado Global mean sea level

Long-term mean sea level change is a variable of considerable interest in the studies of global climate change. The measurement of long-term changes in global mean sea level can provide an important corroboration of predictions by climate models of global warming. Long term sea level variations are primarily determined with two different methods. Over the last century, global sea level change has typically been estimated from tide gauge measurements by long-term averaging. Alternatively, satellite altimeter measurements can be combined with precisely known spacecraft orbits to provide an improved measurement of global sea level change.
Since August 1992 the satellite altimeters have been measuring sea level on a global basis with unprecedented accuracy. The TOPEX/POSEIDON (T/P) satellite mission provided observations of sea level change from 1992 until 2005. Jason-1, launched in late 2001 as the successor to T/P, continues this record by providing an estimate of global mean sea level every 10 days with an uncertainty of 3-4 mm. The latest mean sea level time series and maps of regional sea level change can be found on this site. Concurrent tide gauge calibrations are used to estimate altimeter drift. Sea level measurements for specific locations can be obtained from our Interactive Wizard. Details on how these results are computed can be found in the documentation and the bibliography.

Newswise Science News | Global Temperature Report - July 2009

Newswise — The global average temperature jumped 0.41 C from June to July, the largest one-month jump in the 31-year global temperature record, according to Dr. John Christy, director of UAHuntsville’s Earth System Science Center. The global average went from normal in June to the second hottest July on record.

“Part of that is an artificial artifact of where we put the calendar boundaries,” Christy said. “Warmth from the new El Nino was not felt at all in June but really got going almost from the first day of July.”

At 0.41 C warmer than seasonal norms, July 2009 was second only to July 1998 (+0.51 C). July 1998 was on the back end of the most powerful El Nino Pacific Ocean warming event of the 20th century. That El Nino also caused the warmest monthly average temperature in the climate record: +0.77 in April 1998.

At 0.61 C warmer than seasonal norms, temperatures in the Southern Hemisphere in July tied May 1998 (during that big El Nino) as the second warmest month south of the equator. It was also the second warmest month on record in the Antarctic, where the average temperature was 3.11 C (about 5.60 degrees Fahrenheit) warmer than seasonal norms for the Antarctic winter. The warmest (compared to seasonal norms) was May 2002, when the continent’s average temperature was 3.30 C warmer than normal.
