Climategate: Un-Hiding the Decline
Steve McIntyre writes on the Climate Audit mirror site:
For the very first time, the Climategate Letters “archived” the deleted portion of the Briffa MXD reconstruction of “Hide the Decline” fame – see here.
Gavin Schmidt claimed that the decline had been “hidden in plain sight” (see here. ). This isn’t true. The post-1960 data was deleted from the archived version of this reconstruction at NOAA here and not shown in the corresponding figure in Briffa et al 2001, though pre-calibration values were archived in a different NCDC file here. While the decline was shown in Briffa et al 1998 and Briffa 2000, it was not shown in the IPCC 2001 graph, one that Mann, Jones, Briffa, Folland and Karl were working in the two weeks prior to the “trick” email (or for that matter in the IPCC 2007 graph, an issue that I’ll return to.) For now, here is a graphic showing the deleted data in red. A retrieval script follows.
