Here, we present and analyse the first composite speleothem annual growth-rate record based on five stalagmites from the same cave system in northwest Scotland, where precipitation is sensitive to North Atlantic climate variability and the winter North Atlantic Oscillation (NAO). Our 3000-year record confirms persistently low growth-rates, reflective of positive NAO states, during the Medieval Climate Anomaly (MCA). Another persistently low growth period occurring at 290-550 CE coincides with the European Migration Period, and a subsequent period of sustained fast growth-rate (negative NAO) from 600-900 AD provides the climate context for the Viking Age in northern and western Europe. STUDY NOTES: This is the final compilation of stalagmite growth-rate data from Uamh an Tartair cave, Sutherland, northwest Scotland. Uamh an Tartair (Cave of the roaring), is located near Inchnadamph, Sutherland, northwest Scotland. Individual stalagmite growth-rate series are archived with a new composite series, SUcomp. The 3000 year composite stalagmite growth rate record has an instrumental-period calibration with the North Atlantic Oscillation, so it is also a long annually-resolved proxy record of the NAO and effectively an extension of the NAO reconstruction of Trouet et al. 2009, Science 324:78.
