Objectives

Millennium has a single clear objective: to determine with quantifiable precision whether the magnitude and rate of 20th Century climate change exceeds the natural variability of European climate over the last millennium. To do this the very best documentary, biological and sedimentary archives available across Europe and the most powerful techniques will be used to extract palaeoclimate signals. Multi-proxy climate reconstructions of unparalleled accuracy and precision will be produced. Combined with existing instrumental and proxy palaeoclimate data, our results will allow us to model the past and future impacts of anthropogenic climate forcing using realistic patterns of natural climate variability across Europe. Next to treeline in Laanila, northern Finland we will apply the innovative Needle Trace Method, NTM, to produce a 1200-year-long height-increment chronology for Scots pine from which also evenly long tree-ring width, tree-ring density and stable isotope (C, O, H) series are produced. From all these proxies the climate signal will be extracted separately to reconstruct past climate for the one thousand years in northern Fennoscandia. The signal will then be strengthened by a multiproxy approach in order to model the European climate.
