Northern Hemisphere Extra-Tropics 2,000-year Decadal Temperature Reconstruction

Multi-proxy temperature reconstruction for the extra-tropical Northern Hemisphere (90-30°N) during the last two millennia based on 30 palaeotemperature proxy records with annual to multi-decadal resolution. Proxy types include historical documentary records, seafloor sediment records, lake sediment records, speleothem records, ice-core records, varved thickness sediment records, tree-ring width and maximum latewood density records. The reconstruction is presented as decadal anomalies in degrees C relative to the 1961-1990 reference period and provided with quantitative error bars.
