Okay, so 9 pages later and I still haven't seen anyone explain the frequency and volume of historical data changes...
Has anyone here actually looked at the available source papers from gistemp ? I'm talking about each and every single one from each and every single
month that they replace the previous month's with at this site
You will see that these data sets are getting updated on a monthly basis as they plug the new current month's numbers in so the old reports are no
longer there and are apparently not made available via archives of any kind either.
You can also download PM’s excel spreadsheet here
Looking at the spreadsheet/workbook, you can see that he was only able to recover 11 archived reports: 2005-Nov, 2005-Dec, 2007-Aug, 2007-Sep,
2007-Oct, 2007-Nov, 2010-Aug, 2010-Sep, 2010-Oct, 2012-Aug, 2012-Sep. Any and all other missing months going all the way back to when they first
started publishing these monthly reports have completely disappeared into the abyss and are unrecoverable for whatever reason. So just going by 11
months worth, the historical numbers have been changed each and every time. Which, statistically speaking, tells me that they are very likely
changing on a monthly basis, month after month, year after year just by going off the one's that PM does have.
GHCN and Reynolds newer versions of their programs can only explain some of the changes, but still does not come anywhere near to explaining the
hundreds of changes that have actually occurred to the already so-called "homogenized" "re-calibrated" "tweaked" "twiddled" data for, say
Can anybody explain why old data needs to be "tweaked" on a monthly basis over a period of a gawd knows how many years ?! How many times do these
climatologists need to "revise" historical data to account for "newer technological precision in measurements" ?!
This is the summary of the main point that PM is trying to get to. A few changes here and there can easily be explained, but on a monthly basis for
years on end ?
Thus far, I've only seen posters logically explain away a few of those changes... but definitely not all, or even anywhere near the volume of changes
that we're talking about here.
Come on people, there is no logical explanation for that many changes (if these constant changes are “legitimate” in their purpose for having to
be done) !
I don't care if the numbers represent anomalies, or mean anomalies, or temperatures, or mean temperatures, or whatever... this data should not be
changing as much as it does.
Oh, and by the way… just for a good laugh… if you now go to the gistemp site and look at the numbers for 1880, they’ve already changed again !
A day or two ago the data for 1880 for January and February has changed from being -47 and -31 to now being -48 and -32 !! Hell, I haven’t even
bothered to look at all the other numbers, just those first two caught my eye to jump out and scream “What the hell?”. All I did was have a quick
glance at that report again today before typing out this post…
Holy ripped nylons, Batman… what the hell are these people doing ?!
