Abstract:
Reconstructions of past climate based on pollen data have formed a robust approach and produced a great of products in time
scales from a millennium to ten millenniums. However, it is an attempt for reconstruction of the past decade-century climate
in the Global Change field. This note reports a reconstruction of the past 1000-a temperature in a 50-a scale in Canada based
on pollen data. Because there were little human activities during the last 1000 years in North America, the climate in the
period mainly responded to natural changes. The reconstruction of a natural-forcing change in the climate can provide a basis
to recognize the climate changes impacted from human activities in China. The technique of modern analogue can be implemented
to reconstruct the past millennium climate in China.
