I read this as "no, it wouldn't show up".
"Had there been such a global warming before, it would very likely have registered clearly in some of these data series, even if it didn’t show up in the averaged Marcott curve."
I'm not arguing their conclusions. I'm criticizing the way they present this data. This composite reconstruction is so weak, that if you shifted 20th century AGW back 5,000 years, it would completely erase it. That's how powerful the smoothing is.
- _delirium 13y agoI can buy that view, yeah. It presents conclusions that are probably true, but the plot is a bit in the pop-science direction in doing so, in the sense that the plot itself is not really a rigorous way of establishing those conclusions. The paper doesn't include this kind of plot, probably for those reasons.
