- Title
Palaeotemperatures from tree rings and the D/H ratio of cellulose as a biochemical thermometer.

- Abstract
DENDROCHRONOLOGY can provide sequences of tree rings from various parts of the world. The wood making up these rings can be accurately dated to ±1 yr. Samples can be obtained going back a considerable time, for example wood from Pinus aristata (Bristle Cone Pine) trees can be obtained which goes back beyond 9,000 yr BP. If the isotopic ratios of the elements in the individual constituents in the wood contain a record of past climate, it may enable a curve of a climatic variable like temperature to be determined on a time base accurate to ±1 yr.
