I’ve got to get back to the NAS presentation and this will be my last post on Polar Urals and Yamal for a while, but it is all quite delicious. Anyway, here is a spaghetti graph of 3 Polar Urals results – including the results from Esper et al  just disclosed by Science, all standardized on 1902-1980 in standard Hockey Team fashion. Just put on your Hockey Team 3-D spectacles and you’ll be able to see that the spaghetti graph shows a remarkable similarity between the 3 reconstructions.

Here’s what it looks like if it’s scaled on the full series.
