The chronology shares a moderate to strong positive correlation with local summer temperatures (r = 0.6, p < 0.001) over the calibration period, and moderate to strong correlations with several other reconstructions from surrounding regions spanning the last millenium.;Rejected - not 300 years long #------------------ # Publication # Authors: Porter, Trevor J.;Pisaric, Michael F.J.;Kokelj, Steven V.;deMontigny, Peter # Published_Date_or_Year: 2013 # Published_Title: A ring-width-based reconstruction of June–July minimum temperatures since AD1245 from white spruce stands in the Mackenzie Delta region, northwestern Canada # Journal_Name: Quaternary Research # Volume: 80 # Edition: # Issue: 2 # Pages: 167-179 # Report: # DOI: 10.1016/j.yqres.2013.05.004 # Online_Resource: doi.org # Full_Citation: # Abstract: #------------------ # Publication # Authors: Porter, Trevor J.;Pisaric, Michael F.
