GISS data: manipulated?

I am a little late with this, but my good friend, Bishop Hill, is rather more adept at consistently tracking the climate change loonies and has raised an interesting post...

As you may know, shrieking climate change priest, James Hansen, is the head of NASA's Goddard Institute of Space Studies (GISS) and it is his extremely dodgy land record that provides much of the "evidence" for a warming globe.

Obviously, your humble Devil has highlighted many of the inconsistencies, inaccuracies, fabrications and downright lies that have emanated from GISS over the years; however, I am even more happy to bring you a critique of the whole of the GISS data set.
David Stockwell is an Australian statistical expert who has written a book covering, among other things, statistical tests for detecting datasets which have been manipulated in some way. He also has a blog called Niche Modelling which is well worth a visit.

His latest post outlines the results of running one of these fraud-busting tests on NASA GISS's global temperature index, and the results were rather interesting....
RESULT: Significant management detected.

In other words, it is highly probable that the GISS temperature readings have been deliberately tampered with, over and above the inherent problems in the collection of said data.

As more and more of the warmists' articles of faith start to crumble, there are some people who are going to look very stupid. And there are others, like Hansen, who should very probably be prosecuted...

Much as I'm a "denier" and also convinced that Hansen is cooking his figures, sorry, "adjusting" for UHI etc etc., I don't think that he's being as blatant as this report suggests.

Certainly, the author of the software has later said that he isn't sure either and it was examined at "Climate Audit" (probably the most authoritative blog of the lot) who decided that there was no "smoking gun".

GISS figures are "adjusted" - just not quite so blatantly.

Your humble Devil apologises for his lack of posting: it has become increasingly difficult to actually put quill to vellum, as it were.

It's not purely that the political situation is rather uninspiring, it is also that I have become very much out of the habit of writing (about politics, at least). As such, every time that I fire up the blogging screen, I feel an incredible weariness.

I asked Pete to blog here because I thought that contemplating the actual mechanics of leaving the EU was important: I wanted to know, as much as anything. My reasons for voting Leave are actually very similar to Pete's, i.e. the rebooting of democracy and power structures in this country: however, he has a knowledge of the intricacies of the technical aspects that is beyond mine and I thought these worth setting down, here, for the record.

I shall try to post a little more frequently going forward. But, please, be warned that the reasons for eschewing this format haven't really gone away. My…

Gove's legacy?

Michael Gove has, quite honourably, said that it was right for Theresa may to sack him as a minister...
"I had six years when I was a government minister. I had a chance to make a difference - I hope that I did."The reforms that Michael Gove made in his time as Education Secretary will come to be seen as the most significant improvements to the British education system since the late 1800s—particularly in the introduction of Free Schools.

Gove made a difference—and his contribution should never be forgotten.
