There are many details to this report. If you are interested in those more specific details, then read on as I have provided below the official Press Release from NOAA (National Oceanographic and Atmospheric Administration) and the NCDC (National Climatic Data Center).
This report and its finding go hand-in-hand with what I wrote about a few days ago regarding the report about warmer than normal water temperatures. Again, let me state that it seems obvious the earth is warming, That is hard to dispute. But, the BIG question is why? Natural warming, some normal 5000 year cycle of some sort, OR man made global warming?
My feeling is, natural climatic warming is underway. Why? How? How long will it last?
Great questions that I doubt anyone knows the answer to.
So, with that said, here is the report:Global Highlights
The combined global land and ocean average surface temperature for July 2010 was the second warmest on record, behind 1998, at 16.5C (61.6F), which is 0.66C (1.19F) above the 20th century average of 15.8C (60.4F).
The July worldwide land surface temperature was 1.03C (1.85F) above the 20th century average of 14.3C (57.8F)"the warmest July on record.
The worldwide ocean surface temperature was 0.54C (0.97F) above the 20th century average of 16.4C (61.5F) and the fifth warmest July on record. The warmth was most pronounced in the Atlantic Ocean.
La Nia conditions developed during July 2010, as sea surface temperatures (SST) continued to drop across the central and eastern equatorial Pacific Ocean. According to NOAA's Climate Prediction Center, La Nia is expected to strengthen and last through the Northern Hemisphere winter 2010-2011.
For the year-to-date, the global combined land and ocean surface temperature of 14.5C (58.1F) was the warmest January-July period on record. This value is 0.68C (1.22F) above the 20th century average.Introduction
Temperature anomalies for July 2010 are calculated from the Global Historical Climatology Network (GHCN) dataset of land surface stations using a 1961"1990 base period. For merged land surface and SST analysis, temperature anomalies with respect to the 1971"2000 average for land and ocean are analyzed separately and then merged to form the global analysis.

Large portions of each inhabited continent were substantially warmer than average during July 2010, contributing to the global land-only record warmth. The areas with the most anomalous warmth were Europe, western Russia, and parts of eastern Asia. Cooler-than-average conditions were present across western Alaska, southern South America, eastern Kazakhstan, and central Russia. The worldwide land surface temperature was 1.03C (1.85F) above the 20th century average"this value represented the warmest July on record, surpassing the previous record set in 1998. Meanwhile, the worldwide ocean surface temperature represented the fifth warmest July on record. Warmer-than-average SSTs were present across the Atlantic, Indian, and western North Pacific oceans. The warmth was most pronounced in the Atlantic Ocean. Cooler-than-average SSTs were present across the eastern and central equatorial Pacific Ocean, and the southern oceans. La Nia conditions developed during July 2010, as sea surface temperatures (SSTs) continued to drop across the central and eastern equatorial Pacific Ocean. According to NOAA's Climate Prediction Center (CPC) , La Nia conditions are expected to strengthen and last through the Northern Hemisphere winter 2010-2011. Overall, the combined global land and ocean surface temperature for July 2010 was the second warmest July"behind 1998"on record since records began in 1880. The combined global land and ocean temperature anomaly was 0.66C (1.19F) above the 20th century average, falling only 0.04C (0.07F) short of tying the record set in 1998.
According to the Australian Bureau of Meteorology (BoM) , Australia experienced above average maximum and minimum temperatures during July 2010. Regionally, Tasmania experienced its warmest average maximum temperature for July, which was 1.90C (3.42F) above the 1961-1990 average. It was reported that Timber Creek and Bradshaw (located in the north of the Northern Territory) recorded their warmest day for the month as temperatures soared to 37.5C (99.5F)"this value surpassed the previous July record by 0.1C (0.2F). Meanwhile, South Australia had an average maximum temperature anomaly of -0.57C (-1.03F)"its coolest since July 1998.
Average minimum temperatures across Australia were 1.32C (2.38F) above average, resulting in the warmest minimum temperature for Australia since July 1998 and the sixth warmest July minimum temperature since national records began in 1949, according to BoM. Regionally, Queensland had its warmest minimum temperature anomaly for July (2.91C [5.24F]) since 1993 and the third warmest since national records began over six decades ago. The Northern Territory had warmer-than-average minimum temperatures, with 2.12C (3.82F) above average"this was the warmest minimum temperature for July since 1998 and the sixth warmest since national records began. On the contrary, Victoria had below-average minimum temperatures (-0.37C [-0.67F] below average), resulting in the coolest minimum temperature since 1998.
According to the Finnish Meteorological Institute (FMI) , July 2010 was extremely warm across central and southern parts of Finland, setting many new temperature records. Finland set a new all-time maximum temperature record on July 29th when temperatures soared to 37.2C (99.0F) at Joensuu Airport in Liperi, surpassing the previous record set in Turku in July 1914 by 1.3C (2.3F). The month was also characterized by many hot days. It was reported that at Utti, Lahti, Heinola, and Puumala had a total of 27 days (out of 31) that observed maximum temperatures exceeding 25C (77F), setting a new record for number of hot days. The previous record was set in 2003 when 22 days exceeded 25C (77F).
The July 2010 average temperature across China was 22.8C (73.0F), which is 1.4C (2.5F) above the 1971-2000 average"resulting as the warmest July since 1961, according to the Beijing Climate Center (BCC) . The provinces of Shanxi, Inner Mongolia, Yunnan, and Qinghai had their warmest July since 1961, while Beijing, Guangxi, Gansu, and Ningxia had their second warmest July since 1961.
According to the German Meteorological Service (Deutscher Wetterdienst) , Germany experienced warmer-than-average conditions during July 2010. The mean temperature for Germany was 20.3C (68.5F), which is 3.4C (6.1F) above the 1961-1990 average"resulting in the fourth warmest July since 1901, behind 2006, 1994, and 1983.
Moscow, Russia was engulfed by a severe heat wave during much of July. On July 30th, 2010 Moscow set a new all-time temperature record when temperatures reached 39C (102F), exceeding the previous record of 37.2C (99.0F) set four days earlier. Before 2010, the highest maximum temperature recorded in Moscow was 36.8C (98.2F) set nine decades ago.
Below average temperatures were widespread across southern South America during July. According to the Argentinean Meteorological Service , monthly temperature anomalies of 2-3C (4-5F) below average were widespread across the country. A cold snap during the middle of the month brought temperatures 12C (21F) below average for several days. The cold snap also affected Paraguay, Uruguay, Bolivia, Chile, Brazil, and Peru. Minimum temperatures as low as -24C (-11F) were reported in the Andes Mountains. The temperature in Lima, Peru dropped to 8C (46F), the coldest temperature recorded in the city in over four decades.
The January " July temperatures 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 northern Pacific Ocean, along the western South American coast, Mongolia, and central Russia. The combined global average land and ocean surface temperature for January"July period was the warmest such period on record. This value is 0.68C (1.22F) above the 20th century average. Separately, the average worldwide land surface temperature ranked as the warmest on record, while the worldwide average ocean surface temperature ranked as the second warmest January"July on record"behind 1998.
