First the link to this week's complete list as HTML and as PDF.

Still labouring with a drawn-out head cold I'm not up to critiquing Magar et al. At first glance I fail to find any reference to blinding. Perhaps one of my readers will jump in and send me a guest review.

In their response Reich et al. again fail to address the most important problem with their failed experiment. But why should they, when even their published critics ignore the glaringly obvious? Please note that their figure 1 does not depict the “CO2-effect” as they state but the total difference between two sample plots, some of which is probably down to CO2. This would be the main effect if everything else were held more or less equal, but with the raw data wildly swinging all over the place, as they do for C3, this fundamental assumption can not be made.

It has long been observed that kernel sizes rose long before cereals became domesticated. I have only now come across Fuller’s explanation of 2007. This is one more confirmation for cultivation and domestication being two completely independent phenomena. Equating non-domesticated cereal use with gathering from wild patches alone, as is still the mainstream opinion in literature, yields entirely fallacious results.

Koll & Cronin explain a mechanism of positive feedback that makes earth warm more and emit less then would be indicated by incoming and captured radiation alone.
