Short summary
New proxies and improvements in existing methodologies are needed to advance paleoclimate research. This study explored dendroanatomy, the analysis of wood anatomical parameters in dated tree rings, of Engelmann spruce from the Columbia Icefield area, Canada, as a proxy of past temperatures. Our new parameters compare favorably with state of the art proxy parameters from X-ray and visible light techniques, particularly with respect to the temporal stability of the temperature signal.
