The reconstruction is performed using a novel ensemble method, Ensemble-LOC, designed to preserve low-frequency variability and minimize the influence of the "spurious correlation" between the proxy and instrumental data. The reconstruction is based on a set of 22 proxy records with annual resolution. We find clear evidences for a cold anomaly AD ~630 to 770 related to the Dark Age Cold Period, a warm anomaly ~950 to 1050 related to the Medieval Climate Anomaly, and a cold anomaly ~1200 to 1900 related to the Little Ice Age. The strong 20th century warming is also evident. There are 3 different and distinct warm periods occurring during the Little Ice Age: 1470-1510, 1550-1570, and 1750--1770. However, about half of the total input proxies are not used in the large majority of the reconstructions. We still need additional proxy records from the Arctic region with annual resolution and a strong response to local temperature to further verify the results of this study and in order to investigate possible spatial patterns of past Arctic temperature variability.
