One of McIntyre’s repeated complaints about Briffa was that he refused to release his data. For example, in his post Fresh Data on Briffa’s Yamal #1:
A few days ago, I became aware that the long-sought Yamal measurement data url had materialized at Briffa’s website – after many years of effort on my part and nearly 10 years after its original use in Briffa (2000).
I am very grateful to the editors of Phil Trans B (Roy Soc) – at long last, a journal editor stood up to CRU, requiring Briffa to archive supporting data.
This got turned into statements like this one, from Tom Fuller:
The data, which the scientists had refused to release for a decade, came to light when the Royal Society of London demanded they archive their findings before publishing their latest paper.
But now McIntyre has admitted that he had the data all along. The data wasn’t Briffa’s and back in 2006, Briffa referred McIntyre to the original source:
Steve these data were produced by Swedish and Russian colleagues – will pass on your message to them]
When a reader asked him why he didn’t just get the data from the original sources, McIntyre dropped a bombshell:
In response to your point that I wasn’t “diligent enough” in pursuing the matter with the Russians, in fact, I already had a version of the data from the Russians, one that I’d had since 2004.
He had it all along and despite writing thousands and thousands of words about Yamal somehow somehow failed to mention this until now. Truly I am in awe of McIntyre’s ability to make mountains out of molehills.
The only substantive point that McIntyre made was the sample size was small, but Deep Climate reports that you get the same results with a larger sample:
Now comes new evidence that McIntyre’s accusations were completely false. And not only that, one of the Russian researchers who actually control the raw tree-ring data that McIntyre was mistakenly hounding Briffa for, has apparently confirmed that utilization of a newer more complete Yamal data set has no substantial effect on Briffa’s Yamal temperature reconstruction.
Lastly I note that Andrew Bolt back from vacation has used Yamal to declare that:
Belief in man-made global warming will soon be laughed out of existence.
