Climate Change in Southern South America During the Last Two Millennia

摘要: Paleoclimate records from southern South America can be used to address important questions regarding the timing and nature of late-Holocene climate variability. During last 30 years, many areas have experienced rapid climatic ecological changes that are driven by global hemispheric-scale ocean-atmosphere processes. In order place these recent in a longer-term context, we first present an overview modern processes relevant for interpretation paleoclimate America, then review been developed various archives span two thousand years. Multiple provide evidence overall decrease temperature increase westerly wind intensity culminates few hundred years during time European Little Ice Age. We also find aridity generally coincident with Medieval Climate Anomaly several archives. Although much work has done this region, high-resolution well-dated still needed sensitive locations improve our understanding past change.
