Response to Briffa #2

As noted at CA last week, Briffa published a partial response to Yamal issues at the CRU website, one post discussing the impact of the Yamal chronology in various studies and another post discussing the Yamal chronology itself. For a response to Briffa’s online article on the impact of Yamal, I refer readers to last […]

Keith Briffa Responds

In spite of suffering a serious illness (which I understand to be a kidney problem), Keith Briffa has taken the time to comment on the Yamal situation. The comment should be read by interested readers. If Briffa or any of his associates wishes to post a thread here without any editorial control on my part, […]

Mann 2008: the Briffa MXD Network

The same error is repeated in Mann et al 2008, a defect encountered by Jeff Id and myself in trying to replicate reported correlations to gridcell temperatures. Nearly 100 […]

You may recall the observation of one reader in the discussion of Swindle, the reader observing: If a […]

I was planning a new post on the truncation of the inconvenient 20th century downturn in the Briffa 2001 graphic in the IPCC graphic, that I observed some time ago here. Since data truncation is in the news, I was going to update the graphic in this post to better show just how cynical the […]

Polar Urals: Briffa versus Esper

It’s interesting that the Hockey Team seems to be able to make spaghetti graphs of world temperature history when they can’t even arrive at a spaghetti graph for the Polar Urals. I posted up the difference between Briffa’s Yamal substitution and the updated Polar Urals ring widths. But before either one, there was Briffa’s Polar […]
