Although climate scientists keep telling that defects in their “hockey stick” proxy reconstructions don’t matter – that it doesn’t matter whether they use data upside down, that it doesn’t matter if they cherry pick individual series depending on whether they go up in the 20th century, that it doesn’t matter if they discard series that […]
In today’s post, I’ll return to more typical Climate Audit programming. Upside-down Mann’s mentor, Raymond Bradley, has somewhat surprisingly published an article (Balascio et al 2015) that supports a longstanding Climate Audit criticism of varve proxies. Bradley and coauthors did not report that their interpretation of an important Baffin Island series is upside-down to the […]
Kaufman and paleo peer reviewers ought to be aware that the recent portion of varve data can be contaminated by modern agriculture, as this was a contentious issue in relation to Mann et al 2008 (Upside Down Mann) and Kaufman et al 2009. Nonetheless, Kaufman et al 2013 (PAGES), despite dozens of coauthors and peer […]
In today’s post, I’m going to show Marcott-Shakun redating in several relevant cases. The problem, as I’ve said on numerous occasions, has nothing to do with the very slight recalibration of radiocarbon dates from CALIB 6.0.1 (essentially negligible in the modern period in discussion here), but with Marcott-Shakun core top redating.
Another episode in the continuing series – Tiljander and Upside Down Mann.
In the last couple of days, there has been much to-do in glacier world about an error in the Times Atlas on Greenland glaciers. See for example here here here. Unlike the authors of 1000-year temperature reconstructions, glaciologists seem to be concerned about things like using data upside down. As of today, the Times Atlas […]
Obviously, there’s been lots of coverage on Climategate. Jon Stewart’s commentary on the Daily Show neatly rebutted spin by Gavin Schmidt on the “trick”, on the availability of “value added” data and closing with a sensible moral: don’t cut corners. It’s too bad that he wasn’t on the case with Upside Down Mann, where, at […]
When you’re trading in puts and calls (or derivatives), it’s important to know the sign of the relationship between the value of the derivative and the market. Short positions will go up in value as the market goes down. And, unfortunately, you don’t get to decide afterwards whether you wanted to be short or long. […]
On October 18, 2021, BBC (producer Owen Sheers) aired a “conspiracy thriller” entitled The Trick – though a more complete title would have been The Trick… to Hide the Trick to Hide the Decline. In a forthcoming post, I’ll do a longer analysis of the trick in which, to borrow a phrase from Climate Audit […]
Mar 2, 2021. This post was written in 2015 but, for some reason, I didn’t publish it at the time. Seems just as valid today as when it was written. Esper et al 2012, Orbital Forcing of Tree Ring Data pdf SI, is one of the few paleoclimate articles in past decade which really […]
