I missed this last summer....the updated PAGES 2K was published.
PAGES 2K is the most comprehensive dataset in paleoclimate research, collected from dozens of different climate proxies on a global scale that can give us the best estimate of what global temps have been the last 2000 years or so.
This database keeps on expanding, and future publications will continue to help refine and narrow the uncertainty ranges. It currently has almost 700 different records from about as many locations distributed worldwide.
Publication is here:
A global multiproxy database for temperature reconstructions of the Common Era | Scientific Data
And Stephan Rahmsdorf, the well known oceanographer and climate scientist has posted this helpful graph, showing how the Pages 2k data fits in with the Mann Northern Hemisphere data and the current directly measured temperature records.
You can see how the absolute mass of data here has really narrowed the uncertainty ranges since the original MBH99 paper.
Looks like we have enough hockey sticks now for an NHL team.
I look forward to hearing all the armchair experts explain how these hundreds of scientists who contribute to this (who are by definition the top people in their field) have no idea what they are doing.
