Several analyses of ring width and ring density chronologies, with otherwise well - established sensitivity to temperature, have shown that they do not emulate the general warming trend evident in instrumental temperature
records over recent decades, although they do
track the warming that occurred during the early part of the 20th century and they continue to maintain a good correlation with observed temperatures
over the full instrumental period at the interannual time scale (Briffa et al., 2004; D'Arrigo, 2006).
