Climate scientists performing analysis of Scots pine trees over an 810-year period for a summer temperature reconstruction discover that temperatures were warmer in the periods around 1300s, 1500s, and 1730s.
Abstract: This study presents a summer temperature reconstruction using Scots pine tree-ring chronologies for Scotland allowing the placement of current regional temperature changes in a longer-term context.
‘Living-tree’ chronologies were extended using ‘subfossil’ samples extracted from nearshore lake sediments resulting in a composite chronology >800 years in length. The North Cairngorms (NCAIRN) reconstruction was developed from a set of composite blue intensity high-pass and ring-width low-pass filtered chronologies with a range of detrending and disturbance correction procedures.
