Spiked magazine has taken a look at the Marcott hockey stick and is singularly unimpressed:
On Easter Sunday, Marcott and his colleagues published a response on the Real Climate blog. Most notable was this comment: ‘Our global paleotemperature reconstruction includes a so-called “uptick” in temperatures during the twentieth century. However, in the paper we make the point that this particular feature is of shorter duration than the inherent smoothing in our statistical averaging procedure, and that it is based on only a few available paleo-reconstructions of the type we used. Thus, the twentieth-century portion of our paleotemperature stack is not statistically robust, cannot be considered representative of global temperature changes, and therefore is not the basis of any of our conclusions.’
Wow.
In other words, all that stuff about having the highest temperatures for millennia and about eye-popping warming over the past 100 years appears to have no basis in the paper’s actual temperature reconstruction.
I get a mention too.
