Short summary

Blue intensity shows great potential for reconstructing past summer temperatures from conifer trees growing at high latitude or the treeline. However, conifer species that express a strong colour difference between the heartwood and sapwood can impart a long-term trend bias in the resultant reconstructions. Herein, we highlight this issue using eight mountain hemlock sites across the Gulf of Alaska and explore how a non-biased reconstruction of past temperature could be derived using such data.
