Great Scandal in First IPCC report

All well-informed people must have heard of the notorious so-called Hockey Stick graph by the equally notorious Michael Mann and his accomplices. An alleged attempt to reconstruct northern hemisphere temperatures during the last millennium, it featured prominently in the third IPCC report, published in 2001. Its inclusion in that report is considered to be one of the greatest scientific scandals ever.
But there is an ever greater scandal that is waiting to have its story told. It concerns the first IPCC report, published in 1990. This report features another millennial temperature reconstruction (below).

This graph is commonly referred to as the “Sickle graph” because of its sickle-like shape (compare to the picture below).

Note that the sickle is a commonly used symbol for communism.

The “Sickle graph” is based on the work of Hubert Lamb, who also is the founder of the notorious Climate Research Unit at East Anglia University, of Climate Gate infamy (hardly a mere coincident). And if one investigates the origin of the graph, it turns out that it is not at all global, as claimed by the IPCC, but merely covers Central England!
This was in 1990, which was much closer to the medieval period than 2010 (ie the present year), and yet this was the best they could do. A crudely drawn graph for Central England (loaded with communist symbolism), and not even calibrated against present temperatures! Then one can only imagine how much worse our knowledge of medieval temperatures must be today, twenty years later.
Do you all see now what a terrible fraud this is? And the fraud has been successful: even many skeptics unknowingly use this disgraceful and discredited graph, a cruel mockery of everything that is good and pure in science! It is utterly unacceptable. Don’t let the alarmists keep this outrageousity buried any longer. After all, this is in the primary IPCC report – the most important of them all. This scandal will bring down the IPCC once and for all, and put an end to its reign of terror. And in particular, Bert Bolin must immediately resign as the first IPCC chair!

All skeptical bloggers must write about this scam of unprecedented proportions! Anthony Whats, Steve McIntyre – you must immediately help me to let the entire world know! Professor Wegman must immediately start a new investigation, and congressman Joe Barton must commission it!

My dear fellow skeptics, pit bulls for truth: this time we surely have the IPCC by the balls, and we will not let go!
