A current paper in Nature from a long list of authors, including Neukom, Gergis and Karoly, on Southern Hemisphere proxies, is attracting attention. It's emphasis is on inter-hemispheric comparisons. The paper is here, the extensive SI here, and the data here. A press release is here.
There are critical posts at WUWT (here and here) and at Climate Audit.
So far I don't have an opinion on the study itself. But as with previous studies by Marcott et al and Pages2K, I have posted an active viewer, which gives easy access to plots and metadata. It's below the jump.
Update: I've added a choice of range. You can click on 2000 years to see the full range, or 400 years to see post-1600 on an expanded scale.
The methods are as for the Marcott viewer. The spaghetti curves are colored as their labels; since the proxies are ordered longest first, this creates a rainbow pattern. The annual data (2000 years) is very noisy, so I smoothed with a 10-year boxcar filter.
One of the tedious tasks here was getting a formatted table from the pdf Table 5 in the SI. I have put up a csv file of that table here.
At some stage I'll do a composite viewer for Marcott, Pages2K and Neukom.
There was a slight discrepancy between the order of proxies in Table 5 and the order of columns in the data. I've reset the Table 5 order to mtch.
