Another Upside-Down PAGES2K Non-Corrigendum

Mar 17, 2015 – 8:37 PM

Kaufman and McKay recently and quietly issued an Arctic2K correction file at NOAA xls here (now here)  that concedes yet another upside-down series previously pointed out to them at Climate Audit. Once again, they used information from Climate Audit without acknowledgement or credit (see NSF definition of plagiarism here).

New Article on Igaliku

The resulting reconstruction has been substantially revised with substantially increased medieval warmth.

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 […]
