But before they release it to the public,  they put it thorough a series of adjustments which [[global warming/claims/altered data|change it from a cooling trend to a warming trend]]."</call>
===Notes===
* This page appears to be a log of updates to the dataset: [http://data.giss.nasa.gov/gistemp/updates_v3/ GISS Surface Temperature Analysis: Updates to Analysis]
* The "deleted" data linked to with the text "gistemp/graphs/FigD.txt" is also available [https://web.archive.org/web/20030301155249/http://www.giss.nasa.gov/data/update/gistemp/graphs/FigD.txt on archive.org].
* The article doesn't bother to provide the data in spreadsheet format, for readers to examine in more detail; that is available [[:File:2014-07-11 climate data comparison.ods|here]]. A graphical comparison is [[media:2014-07-11 climate data comparison.svg|here]] - new data in pink, old data in blue with connecting lines
* The article doesn't cite any NASA pages that link to the data, in order to clarify its context. Here are some:

** [http://data.giss.nasa.gov/gistemp/graphs_v3/ GISS Surface Temperature Analysis]
* Another version of the data is available [http://data.giss.nasa.gov/gistemp/graphs_v2/Fig.D.txt here], via [http://data.giss.nasa.gov/gistemp/graphs_v2/ this page]
* Favorable commentary on this article:

<blockquote>
<p>The page with the figure you mention in your email has been created manually until recently and no data have been displayed in the past on that page for periods that partially lie in the future.</p>

<p>However, when I automated the creation of that page there was one program � the one that finds the US annual means � that missed the feature not to produce such means.</p>

<p>That oversight � which had no effect until this month � has been corrected and you should only see on our temperature web site estimates for periods that lie completely in the past. The 2012 US mean anomaly estimate will not be shown in that display before January 2013.</p>

<p>Thank you very much for notifying us. We appreciate and as far as I know always responded to any notification of an actual or suspected error on our web page. If I ever failed to respond to any of your emails to GISS, please forward them to me � I could not find any in my mailbox.</p>

<p>I am familiar with and appreciate your work examining the quality of temperature reports and want to thank you for that effort.</p>

Despite this, the anti-GW blogosphere continues to report this as clear malfeasance:
