The Climate of Gavin: How GISS Have Changed The Temperature Record Since 2008
Guest post by Paul Homewood
I ran a post yesterday, showing how the latest version of GISSTEMP had changed from using Hadley/Reynolds to ERSST for ocean temperatures, with the result that about 0.03C had been added to recent warming.
However, this is not the only change they have made to the historical temperature record in recent years. Climate4You, fortunately, archived the GISS data in May 2008. Comparing this dataset with today’s version, we can see that about 0.10C of warming, or more, has been added to temperatures in the last decade, compared to data up to about 1950.
Alterations to temperature record 1881-2008
It must be remembered that these are only changes made by GISS since 2008. As I pointed out, prior to 2008, other adjustments of about 0.03C had already been added to the numbers originally declared just a few years earlier. These adjustments must, therefore, also be added on to the adjustments made since.
An adjustment of 0.10C or so may not seem a lot, but the latest GISS anomaly, against the baseline of 1951-80, is 0.44C. These adjustments make up about a quarter of this figure.
I have also done some digging on the original numbers GISS declared for 1998, which seem much different to what they now show. News on this later.

What ever you do don’t play poker against Hansen , he may not be able to forecast the climate worth a dam , but his ‘ luck ‘ with the way all these adjustments support ‘the cause’ he does so very much promote. If seen at the table means you would not stand no chance against him.
The scary thing is not what is going to happen to the temperature of the future, but what is going to happen in the future with the temperature recordings of the past.
Typo in paragraph 4 – “need” should be not.
Wonder how Jan Perlwitz will spin this one.

Schmidt, Hansen, and Reudy have quietly, merrily been committing fraud for years – and trying to erase their tracks
‘An adjustment of 0.10C or so may need seem a lot’
Typo : for ‘need’ read ‘not’!?
This site used to carry the statement “Not evil, just wrong”. That may well apply to most of devotees and many of the proponents of the CAGW creed. It is overtime to continue to pretend it applies to all. There are enemies of humanity involved in this.
They, their actions, their manipulations, their destruction of human capacity to see reality, need to be cataloged. Be they “scientists”, “activists”, “journalists”, functionaries businesses politicians or toadies. The day is fast approaching when the world will judge them, and the evidence needs to be gathered and stored.
This is the most disturbing part of the Hansen game. NASA has to know this, how can they allow this? Data is sacrosanct, or should be.
“An adjustment of 0.10C or so may need [not] seem a lot, but the latest GISS anomaly, against the baseline of 1951-80, is 0.44C. These adjustments make up about a quarter of this figure.”
Indeed, when the claimed basis for CAGW projections is all about several tenths of a degree, each bit matters. In the example of U.S. temperature history, Hansen’s GISS changed it over a key period by at least around 0.3 degrees, as seen by comparing plots within the latter portion of http://s7.postimage.org/69qd0llcr/intermediate.gif (click to enlarge).
By actions like that, they avoid having plots widely distributed to public view become relatively closer to data like http://earthobservatory.nasa.gov/Features/ArcticIce/Images/arctic_temp_trends_rt.gif or that in the old National Geographic article at http://tinyurl.com/cxo4d3l
Those who aren’t really bothered in the slightest by the preceding do likewise with sea level rise history (actually less rise in the 2nd half of the 20th century than in the first in trustworthy data in contrast to claims otherwise), cloud cover history, solar history, arctic ice history, and just about everything.

“..may not seem a lot”?
Just sitting here, having a Greggs Pasty, in my office overlooking the Thames and watching some white fluffy stuff falling from the sky. That can’t be snow can it? I thought…
If it wasn’t for the UAH and RSS temperature datasets ‘keeping them honest’ since 1979, I wonder what kind of adjustments GISS would be making.
Ministry of Truth, need I say more.
If GISS have managed to add 0.1 degree of warming in 4 years, then by the turn of the next century they will have made adjustments of 2.2 degrees. That’s 2.5 degrees per century. We’re doomed!
“These adjustments make up about a quarter of [the present claimed temperature anomaly].”
That is small potatoes, compared to the fraud Steven Goddard has uncovered in the USHCN temperatures, from which I readily found that
US Temperatures Have Been Falsely Adjusted According to the Level of Carbon Dioxide in the Atmosphere
GISTEMP uses a horrible algorithm for interpolating and infilling the data, so much so that it;s not even useful to call anything it produces a “temperature”. I encourage everyone to check out the paper on which it is based to see this for themselves:
http://pubs.giss.nasa.gov/abs/ha00700d.html
By the way, with regard to the recent U.S. warm temperature “record: of 2012, it is instructive to remember what climate sage Gavin Schmidt (of the infamous NASA/GISS) said about 5 years ago…

Hansen has followed up his “Lights Out Upstairs” outburst with another outburst dismissing critics as “court jesters” with whom he will have no truck. (Lights Out is now cited on the NASA website.) His new jeremiad re-iterated the position of NASA spokesman Gavin Schmidt that U.S. errors “didn’t matter” because the U.S. was only 2% of the earth’s surface.
(Heh!)
Steve Goddard at Real Science shows similar warming adjustments with blink before/after comparisons.
Data Tampering At USHCN/GISS
” Climate4You, fortunately, archived the GISS data in May 2008.”
I hear this ‘fortunately archived’ thing quite a lot. Is there any way of starting a systematic archiving of all this data that gets ‘adjusted’ so much? Or does the Wayback machine do that for us nowadays.
I just hope that the original GISS figures are archived somewhere independent.
There is a case for a website solely devoted to tracking the difference between temperature data as presented in the 1970s, 80s and 90s and nowadays.
Jo Nova had this set of graphs showing the changes Hansen made to the GISS temperature graphs. link
Without the adjustments it looks like we are actually cooling since the 1940’s peak. This would be expected link from link

On the contrary: “Unlucky at cards, lucky at data manipulation.”

When bankers in the UK fiddled the Libor rate the police were called in because billions was being traded based on false information.
But when trillions is being traded on false information which is scandalously fudged … it’s OK because Hansen only earns a million from his fudge and a trillion doesn’t sound as bad as a billion.
Or am I missing something? Is it criminal to fiddle statistics for your own gain whoever you are?
Remove the “adjustments”, and is it still an “age of flatness” or is the temperature actually decreasing?
