Thus the method used above by Gavin is right and it is no surprise that
HadCRUT finds similar uncertainties.
When I checked
Hadcrut i found an increase of ca 7,2 C from 1880 to 2013.

What would have Dole et al. (and you) have
found for July and August trends had you looked at NCDC or
HadCRUT?
While reviewing the bounty of solar and climate information
found at the Global Warming Science site, we
found the adjacent chart (this is the «C3» revised version using annual
HadCRUT global temperatures instead of monthly).
These are not unique to
HadCRUT but are also
found in GISTEMP and NCDC temperature curves.
Well this guy adjusts the temperature records, including
HadCRUT, for ENSO and solar cycle and
finds the warming continues: http://tamino.wordpress.com/2011/01/20/how-fast-is-earth-warming/

I have done these sort of checks for the GISS and
HADCRUT data and what you
find is that for the yearly data ending in 2007, there is strong sensitivity to the data set used and how many years are included out to be about 10 years or so.
I realised
HADCRUT could be trusted, when I went back to check my figures a year later and
found that nothing was the same any longer.
Every time I've looked for an explanation of something GISS or
HadCRUT does, I could
find the answer.
