More fraud in climate science

Fraudalent data

Steve McIntyre, the man who had demonstrated that Michael Mann’s hockey stick graph was a fraud, has now demonstrated that the work of a group of climate scientists attempting to resurrect it is even more fraudulent. It seems that in order to recreate the illusion of warming in the past four hundred years, the scientists, led by geologist Shaun Marcott, changed the dates on a series of ocean cores in order to get the results they wanted.

McIntyre found that Marcott and his colleagues used previously published ocean core data, but have altered the dates represented by the cores, in some cases by as much as 1,000 years.

Most significantly, the scientists made no explanation for changing these dates. It is as if they wanted to hide this decline, y’know?

The chart on the right, by McIntyre, illustrates the fraud. The black line shows the temperature numbers of the ocean cores used by Marcott. The red line shows the temperature numbers, as originally published in the scientific literature, for these ocean cores.

The discrepancy here is so egregious that it screams at you. More important, as John Hinderaker says,

The new hockey stick

Steven Hayward at Powerline has noted a new hockey stick graph, produced by scientists and described in detail by the journal Nature. This one is not specifically about climate, but about the reliability of science and the peer-review process itself. To quote the Nature article:

[Retraction] notices [of science papers] are increasing rapidly. In the early 2000s, only about 30 retraction notices appeared annually. This year, the Web of Science is on track to index more than 400 (see ‘Rise of the retractions’) — even though the total number of papers published has risen by only 44% over the past decade.

Below is the graph from the Nature paper. As Hayward says, “Lo and behold, it looks like a hockey stick! (Heh.)”
