TEX-86 proxy for past ocean temperature reconstructions challenged, possible 21°C error

From the UNIVERSITY OF WASHINGTON Lab experiments question popular measure of ancient ocean temperatures Understanding the planet’s history is crucial if we are to predict its future. While some records are preserved in ice cores or tree rings, other records of the climate’s ancient past are buried deep in the seafloor. An increasingly popular method…

Mining proxies for the Southern Annular Mode

Steve McIntyre writes about what he considers another “completely worthless” exercise in statistical data mining, writing: =============================================================== In today’s post, I will look at a new Naturemag climate reconstruction claiming unprecedentedness (h/t Bishop Hill): “Evolution of the Southern Annular Mode during the past millennium” (Abram et al Nature 2014, pdf). Unfortunately, it is marred by…

Duke Neukom’s Secret Sauce

Guest Post by Willis Eschenbach In my last post, I talked about the “secret sauce”, as I described it, in the Neukom et al. study “Inter-hemispheric temperature variability over the past millennium”. By the “secret sauce” I mean the method which is able to turn the raw proxy data, which has no particular shape or…

Neukom’s Science By Proxy

Guest Post by Willis Eschenbach Over at Climate Audit, Steve McIntyre is engaged in the slow public defenestration of the latest multi-proxy extravapalooza, a gem of a paper yclept “Inter-hemispheric temperature variability over the past millennium” by Neukom et al, hereinafter Neukom2014. Not content with simply creating a thousand-year temperature reconstruction for the Southern Hemisphere,…
