ABSTRACT:  May–September temperatures were reconstructed for the past 250 yr based on Dahurian larch Larix gmelinii Rupr. growing in permafrost region of Northeast China. The reconstruction accounts for 39.3% of the actual temperature variance over the period 1958–2008. The reconstruction captured 3 relatively cold periods in 1847–1852, 1861–1866 and 1935–1941; 2 relatively warm periods in 1874–1879 and 2001–2008; and a persistent warming trend since the mid-20th century. The long-term changes in temperature documented here correspond well with regional temperature change from observational records, other global and regional proxy-based temperature reconstructions, and documented changes in regional permafrost. Thus, valuable information might be preserved in our reconstruction about local- to regional-scale climatic variation during the past 2.5 centuries.
