Climate Scientist Dr. Judith Curry on new ‘Hockey Stick’ paper: ‘I personally don’t see how this analysis says anything convincing about climate variability on the time scale of a century’
…
Analysis of new ‘Hockey Stick’ paper: ‘The MWP did not completely disappear in this new paper, it turned into a <0.1°C blip colder than 1961- 1990. This is quite curious’
The paper itself said, “…our temperature stack does not fully resolve variability at periods shorter than 2000 years…”
Evaluate a 300-year MWP using methods lacking 300 year resolution and voila! The MWP turns into a blip diminished by the colder periods on each side.

The misinformation highway took the paper’s figure S3 (below) as a spaghetti chart hockey stick of the proxy temperatures. It is not. It shows 1000 Monte Carlo simulations of the 73 data sets, perturbed by inserting random temperature and age calibration errors to establish the blue statistical band in Figure 1B. S3 doesn’t say the last century’s temperature has risen above the Holocene peak. It only says uncertainty about the combined recent paleotemperature has risen.

Marcott neglected to tell NPR his methodology did not recognize ‘fast’ century changes at all–until recent thermometer records were spliced onto the 73 paleosites
