摘要

Global surface temperature shows an increasing trend over the past 100 years.Anthropogenic and natural factors have been invoked to explain this warming, but their relative contribution and the spatial variability remain controversial.Based on a 2650-year temperature record from a stalagmite near Beijing, we explore the possible impacts of human activity on the warm season temperature in Beijing since the industrial era using the method of singular spectrum analysis (SSA).The results suggest that the warm s...
