Reconstructing the Paleo ENSO records from tropical and subtropical ice cores

ABSTRACT

Interannual variability in climate is a major feature of the climate system, particulary in subtropical and tropical regions. It is essential to know if the interannual variability signature in the climate records is affected by a change in the mean state of the climate system. This goal can be met only by analyzing long records of interannual climate variability throughout intervals in the past when climate was different from today (e.g., Little Ice Age, Medieval Warm, last glaciation). This task is especially important as man may be inadvertently altering the mean state of global climate. (AU)
