The comparison to their December release shows that there were 476 changes made
compared to 789 November-December changes at the end of last year.

Here are the number of changes for each month in 2018:

Number of Changes to GISSTEMP's LOTI for 2018:
Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
467 426 458 953 879 429 595 281 439 405 755 789

Compared to LOTI from June 2002 which was the first in the current format, January 2019 looks like this:



If 2018 is representative of of the last 16 years then of the 29,871 monthly entries since 2002, well over
10,000 changes have been made, and all of those since 1970 have averaged out to be increases.

From GISSTEMP's FAQ page:

Q. Do the raw data ever change, and why do monthly updates impact earlier global mean data?
A. The raw data always stays the same, except for occasional reported corrections or replacements of preliminary data from one source by reports obtained later from a more trusted source.

These occasional corrections are one reason why monthly updates not only add e.g. global mean estimates for the new month, but may slightly change estimates for earlier months. Another reason for such changes are late reports for earlier months; finally, as more data become available, they impact the results of NOAA/NCEI's homogenization scheme and of NASA/GISS's combination scheme, particularly in the presence of data gaps.

And another one from the same page:

Q. Does NASA/GISS skew the global temperature trends to better match climate models?
A. No.

Sorry, Steve... but all of these minor changes don't prove anything.
