This bothers me too. I don't know how tree-ring data is interpreted, but it's safe to assume that it's not a simple size of rings -> temperature mapping. How are the myriad of factors that contribute to tree growth accounted for?
- InclinedPlane 17y agoHow are the myriad of factors that contribute to tree growth accounted for? The short answer is that they are not, because they are not known. That's the point. If they were known there wouldn't be nearly so much controversy. Climate history modelling using tree-ring data as a proxy is incredibly immature. It may have value but the degree to which it has been relied upon is all out of proportion to the validity of the current state of the science (which is probably true for much of climate science at the moment as well).
