Indeed, one often sees skeptics clutching at «proxies» that are far, far more shaky than precise measures of tree growth, such as medieval vineyards.

For instance, in Briffa et a 2001 they talk about trees being near altitudinal or longitudinal limits being good candidates because range is limited by temperature (not CO2 concentrations, or precip) and therefore relatively minor changes in temperature cause a relatively larger change in growth rate than trees growing in an area where conditions are more optimum.

Or are you merely saying that tree species are more effective CO2 absorbers — at any stage of growth — than species which have a smaller mature size?

exactly... i recall seeing a graph produced from ice core samples in which the CO2 content of thousands of years past was measured against tree ring data... what it showed was CO2 levels rising 300 years after rapid vegetative growth (natural warming) and incidently the PPM of CO2 measured higher than current levels.

Therefore, it looks like in those locations where temperatures stay too low all year to allow all the photosynthate to be «used up,» temperature can limit growth rate for those trees which can manufacture more photosynthate than can be used up (e.g., those with lots of foliage).

Further evidence comes from a recent review of data for mature trees in four climatic zones, which concluded that pine growth at the treeline is limited by factors other than carbon (Körner 2003).

The impacts of the marked seasonal variability of factors such as net radiation and / or temperature at high latitude sites are of far more importance for tree growth than the small seasonal variation in CO2 (a well - mixed gas).

However, our study suggests that in the field, other factors than carbon or water are limiting tropical tree growth.

Aerial CO2 fertilization is the reason for the increase in plant growth, crop yield, and presumably tree growth for the recent past, where some trees grow at faster rates than others by increasing airborne carbon dioxide concentrations.

Large sample depth during other periods is not then required (a robust curve to remove growth trend is already in hand) except in relation to the general coherence of the tree response to the environmental parameter of interest — if the trees are «noisy» then a larger number of samples will be required to extract signal than if the signal is more coherent.

MWMT and MAP had relatively small effects on tree growth (less than 40 % of the analyzed groups showed significant correlations), whereas the effect of MCMT on tree growth was mostly negative among the detected significant groups (Fig. 3B).

So to attempt to use these data series to model the expected - growth of a tree, you need to allow for the actual age, rather than the age that is given?
