Observed temperatures from July
July 2010 ranked fifth.
From GISS: What global warming looks like
"Will calendar year 2010 be the warmest in the period of instrumental data? Figure 3 shows that through the first seven months 2010 is warmer than prior warm years. The difference of +0.08°C compared with 2005, the prior warmest year, is large enough that 2010 is likely, but not certain, to be the warmest year in the GISS record. However, because of the cooling effect of La Niña in the remainder of the year, there is a strong possibility that the 2005 and 2010 global temperatures will be sufficiently close that they will be practically indistinguishable."
NOAA, surprisingly, ranked July 2010 second-warmest, only behind 1998.
State of the Climate/Global Analysis/July 2010
Interestingly, the lower troposphere temperatures ranked 2nd-warmest from the generated-by-skeptics Alabama-Huntsville analysis, and Warmest from the Remote Sensing System's less-tainted-by-any-obvious-bias analysis. These are also shown in the NOAA report.
