Concord and discord among Northern Hemisphere paleotemperature reconstructions from tree rings

by Scott St. George Jan Esper, December 19, 2018 in WUWT


Highlights

  • Tree rings are the backbone of most last millennium temperature reconstructions.

  • Maximum density is a superior temperature proxy than ring-width but is less available.

  • The newest tree-ring reconstructions agree better with instrumental temperatures.

  • They also fit the memory structure of instrumental temperatures more closely.

  • It is imperative to develop new, long and up-to-date maximum density chronologies.
