Summary: A 2650-year (BC665-AD1985) warm season (MJJA: May, June, July, August)
temperature reconstruction is derived from a correlation between
thickness variations in annual layers of a stalagmite from
Shihua Cave, Beijing, China and instrumental meteorological records.
Observations of soil CO2 and drip water suggest that the temperature
signal is amplified by the soil-organism-CO2 system and recorded by
the annual layer series. Our reconstruction reveals that
centennial-scale rapid warming occurred repeatedly following
multicentennial cooling trends during the last millennia.
These results correlate with different records from the Northern Hemisphere,
indicating that the periodic alternation between cool and warm periods
on a sub-millennial scale had a subhemispherical influence.
