For next week's discussion of proxy records of the El Niño-Southern Oscillation, here are three questions to keep in mind:
1. Describe the basic characteristics of your proxy record. What is the time window that the record covers? What is its temporal resolution? What evidence or approach is the basis for the record's chronology?
2. Briefly describe the line of argument that connects your proxy to the ENSO system. Why might we expect that these data would reflect the influence of ENSO?
3. Based on the 'typical' impact that ENSO has on global climate, what other places might exhibit a good 'ENSO' signal? What proxies might be strongly tuned to those signals?
