Because, with the Copenhagen Climate Fraud Summit starting,

this crap HAS to be hammered over and over,
But more dramatic still has been the new evidence from the CRU's leaked documents, showing just how the evidence was finally rigged. The most quoted remark in those emails has been one from Prof Jones in 1999, reporting that he had used "Mike [Mann]'s Nature trick of adding in the real temps" to "Keith's" graph, in order to "hide the decline". Invariably this has been quoted out of context. Its true significance, we can now see, is that what they intended to hide was the awkward fact that, apart from that one tree, the Yamal data showed temperatures not having risen in the late 20th century but declining. What Jones suggested, emulating Mann's procedure for the "hockey stick" (originally published in Nature), was that tree-ring data after 1960 should be eliminated, and substituted – without explanation – with a line based on the quite different data of measured global temperatures, to convey that temperatures after 1960 had shot up.

A further devastating blow has now been dealt to the CRU graphs by an expert contributor to McIntyre's Climate Audit, known only as "Lucy Skywalker". She has cross-checked with the actual temperature records for that part of Siberia, showing that in the past 50 years temperatures have not risen at all.

I will only add two footnotes to this real-life new version of the old story. One is that, as we can see from the CRU's website, the largest single source of funding for all its projects has been the European Union, which at Copenhagen will be more insistent than anyone that the world should sign up to what amounts to the most costly economic suicide note in history.

The other is that the ugly, drum-like concrete building at the University of East Anglia which houses the CRU is named after its founder, the late Hubert Lamb, the doyen of historical climate experts. It was Professor Lamb whose most famous contribution to climatology was his documenting and naming of what he called the Medieval Warm Epoch, that glaring contradiction of modern global warming theory which his successors have devoted untold efforts to demolishing. If only they had looked at the evidence of those Siberian trees in the spirit of true science, they might have told us that all their efforts to show otherwise were in vain, and that their very much more distinguished predecessor was right after all.

And, speaking of Watts,
On a normal day, Majken Friss Jorgensen, managing director of Copenhagen’s biggest limousine company, says her firm has twelve vehicles on the road. During the “summit to save the world”, which opens here tomorrow, she will have 200. “We thought they were not going to have many cars, due to it being a climate convention,” she says. “But it seems that somebody last week looked at the weather report.”

Ms Jorgensen reckons that between her and her rivals the total number of limos in Copenhagen next week has already broken the 1,200 barrier. The French alone rang up on Thursday and ordered another 42. “We haven’t got enough limos in the country to fulfil the demand,” she says. “We’re having to drive them in hundreds of miles from Germany and Sweden.”

And the total number of electric cars or hybrids among that number? “Five,” says Ms Jorgensen. “The government has some alternative fuel cars but the rest will be petrol or diesel. We don’t have any hybrids in Denmark, unfortunately, due to the extreme taxes on those cars. It makes no sense at all, but it’s very Danish.”

But wait, there’s more!
Red bold mine. Just like Al Gore using enough energy in ONE of his mansions EVERY MONTH to take care of an average family for a year, like the UN climate weenie who's flown almost half-a-million miles the past year- all in first class, of course- to do 'global warming' business,we have the merry socialist nannies lecturing us to "Do what we tell you, don't worry about what we're doing."
