Summary: 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.
