Why is using dendroclimatology not always a true measure of a past climate?

Dendrochronology is the study of data from tree ring growth. Due to the sweeping and diverse applications of this data, specialists can come from many academic disciplines. There are no degrees in dendrochronology because though it is useful across the board, the method itself is fairly limited. Most people who enter into studying tree rings typically come from one of several disciplines: 1.

Explanation:

    Along with the advantages of dendroclimatology are some limitations: confounding factors, geographic coverage, annular resolution, and collection difficulties. The field has developed various methods to partially adjust for these challenges.

There are multiple climate and non-climate factors as well as nonlineareffects that impact tree ring width. Methods to isolate single factors (of interest)
