They note, quite correctly, that the tree - ring response to climate changes much more dramatically between the two time periods than the density response.
The difference between the dense, small - celled late wood of one season and the wide - celled early wood of the following spring enables the age of a tree to be estimated, and the ring widths or density can be related to climate parameters such as temperature and precipitation.
Dano: with your wealth of knowledge about tree rings (I'm not being a smart ass here), can you help us understand the relationship between growth rate / ring density and temperature.
Individual tree rings (or trees) do not exhibit a linear relationship between (whatever — latewood, earlywood, width) and temperature, as there are other confounding factors — site, aspect, stand density, nutrient availability, moisture, as I explained upthread.
The theory does not exist, and there are no physically viable relationships between temperature and tree ring widths or densities.
Up until the 1960s, there is a very close correlation between the density of growth rings in trees in northern latitudes and summer temperatures, but after this it starts to break down.
