Summary

Abstract: The El Nino/Southern Oscillation (ENSO) system is a prominent component of
interannual climate variability, and the Southern Oscillation Index (SOI) is a
primary measure of the state of the ENSO system. Here, we present evidence
that ENSO-related changes in the terrestrial carbon cycle can be recorded by
stalagmites, thus providing a proxy for past El Nino events. Our analysis of a
stalagmite from Belize reveals a strong correlation between the SOI and carbon
isotope ratios (d13C values), even though the site experiences no discernible
local weather effects that are correlated with the SOI. d13C values of this
stalagmite must reflect changes in the overlying rainforest ecosystem's carbon
budget that are sensitive to subtle modifications of local weather related to
ENSO.
