Strip Bark Growth Pulses

Nov 11, 2010 – 12:12 PM

CA readers know that virtually all of the “independent” IPCC reconstructions purporting to compare modern and MWP temperatures use Graybill strip bark chronologies and/or Yamal. In various posts, problems with strip bark chronologies have been discussed, including discussion of Pete Holzmann’s observation based on our sampling at Almagre that strip bark trees seemed to show […]

Miracles and Strip Bark Standardization

Nov 16, 2009 – 12:16 PM

A CA reader has provided a link to an extremely interesting presentation by dendro Brian Luckman of U of Western Ontario (Rob Wilson’s thesis supervisor) at the 2008 Canadian Society of Petroleum Geologists. Reader Erasmus de Frigid draws attention to the inhomogeneity in the tree ring record created when the tree was scarred by a […]

Tamino and the Magic Flute

Mar 26, 2008 – 2:20 PM

Tamino has recently re-iterated the climate science incantation that Mann’s results have been “verified”. He has done so in the face of the fact that one MBH98 claim after another has been shown to be false. In some cases, the claim has not only been shown to be false, but there is convincing evidence that […]

Strip Bark at Upper Wright Lakes Foxtails

Oct 24, 2007 – 9:28 AM

As a sort of Methadone replacement for Mann’s bristlecone PC1 (which uses Graybill’s strip bark chronologies), two Esper foxtail chronologies (Upper Wright Lakes and Boreal Plateau) have come into use by the Team. These two chronologies were used separately in the small Esper network (two of only 7 or so medieval chronologies) making a very […]

Almagre Strip Bark

Oct 17, 2007 – 7:29 PM

I’ve got some preliminary measurement data back on several trees with Graybill tags in digital form. The dendro lab is working on cross-dating this week. The measurement data for our Tree #31 (Graybill 84-56), which Pete Holzmann posted a picture of earlier today, is very interesting. This is a strip-bark tree – remember that the […]
