Pre‐Industrial (1750–1850 CE) Cold Season Warmth in Northeastern China
Abstract Contrary to global warming projections, northern mid‐latitude continents have suffered from an increased frequency of unusually cold winters during the last few decades. However, a lack of longer‐term cold‐season temperature records from mid‐latitudes hampers our understanding of the forcin...

Abstract Contrary to global warming projections, northern mid‐latitude continents have suffered from an increased frequency of unusually cold winters during the last few decades.

By comparing with the instrumental and historical records in the region, we verify the high efficacy of Group 1 alkenones as recorders of cold‐season temperature variability. Our record shows pre‐industrial warmth between 1750 and 1850 CE relative to anthropogenic industrial period (since 1850 CE), which is largely driven by variability of the Arctic Oscillation, with a negligible contribution from anthropogenic greenhouse‐gas forcing.
