Award Description: The aim of this research is to help resolve drivers of Holocene paleoclimate by providing a perspective on Southern Hemisphere glacial and climate changes. Hypotheses concerning how temporal and spatial variability of Southern Hemisphere climate compare with that of the Northern Hemisphere will be tested. A lack of chronologic data is one of the key roadblocks in reconstructing paleoclimate records, even where they are studied. Are there broad trends throughout the Holocene paced by summer insolation intensity (e.g., the Northern neoglacial period)? What happened during the European Little Ice Age (LIA) and Medieval climate anomaly and how dissimilar is climate variability between the northern and southern mid latitudes? Existing observations indicate that the ‘past context’ for present climate change differs between the hemispheres, a hypothesis which we will test. Using recent analytic advances, the new approach that we will take to address the above problems is to use 10Be measurements to date directly with unprecedented accuracy mid to late Holocene moraines. These ages will provide a new perspective, especially when combined with other proxy records, on Southern terrestrial-atmosphere climate variability during the time period.
