"Bishop Hill writes of a new paper, one so “toe curling” it is worth mentioning here to get more exposure. He writes: ......In fact, absence of citations is a bit of an issue. Here’s how Orbach starts to deal with claims about the medieval warm period.
Climate scientists now understand that the Medieval Warm Period was caused by an increase in solar radiation and a decrease in volcanic activity, which both promote warming. Other evidence suggests ocean circulation patterns shifted to bring warmer seawater into the North Atlantic. Those kinds of natural changes have not been detected in the past few decades.
Interesting claims – but where did they come from? We are not told. We are expected to take Prof Obach on trust. At the risk of repeating myself, one would never get away with this kind of thing on a blog.
(PS: Note to Prof Orbach – the ocean near the top of the globe is the Arctic (with a c in the middle). And it’s Santer not Senter."
