IPCC and Solar Correlations

Jan 16, 2007 – 10:23 AM

Here’s a post which I wrote last June but didn’t post up at the time because the NAS Panel report came out and I had other pressing matters to comment on. My post as then drafted started: Last week, through Chefen, Jean S and myself, here here here and here , we showed that MBH98 […]

More on MBH98 Figure 7

May 31, 2006 – 10:55 AM

There’s an interesting knock-on effect from the collapse of MBH98 Figure 7 (see here and here). See update from UC in May 2011 below in which he did a “bit-true” replication. We’ve spent a lot of time arguing about RE statistics versus r2 statistics. Now think about this dispute in the context of Figure 7. […]

MBH98 Figure 7 Unveiled

May 30, 2006 – 6:50 AM

Sometimes we hear that science is "self-correcting". To be "self-correcting", however, individual people have to step up to the plate now and then and actual do the work. To the extent that the term "science" includes the work of Mann et al., then analysis of MBH98 Figure 7 , which was actually the culmination of […]

MBH98 Figure 7

May 29, 2006 – 1:24 PM

Since Chefen has brought this figure into play, there’s much to consider about it. [Also see followup here.] For interested parties, the data is at WDCP here . I haven’t got to checking Chefen’s results yet, but wanted to table interesting results in passing. As Jean S noticed, the Corrigendum stated that an “old” version […]

Something New on MBH98

May 28, 2006 – 12:51 PM

Just when you think that the MBH98 Little Shop of Horrors has been fully explored, something new turns up. I’ve never spent any time on the last part of MBH98, where he does a "detection and attribution" study linking his temperature reconstruction to solar, volcanic and CO2. All these detection and attribution studies (e.g. Hegerl) […]
