Glaciers are considered among the most sensitive indicators of climate change. One of the most visually compelling examples of recent climate change is the retreat of glaciers in mountain regions. Glaciers have also proven to be an important indicator for studying past decadal to century-scale climate variability. Knowledge about the past evolution of glacier fluctuations (over the last millennium and the Holocene) is sparse in South America despite the particular importance of this area. South America spans a range of climates that are influenced by multiple drivers such as the El Niño-Southern Oscillation, Antarctic climate or the high Andes. Further, better knowledge of glacier and climate dynamics in South America is important for future research activities in that area and on a global perspective.This interdisciplinary project will provide new evidence to the South American glacier history and will significantly contribute to the PAGES (Past Global Changes) 2k Network on the reconstruction of climate variability of the last two millennia. New, detailed and highly resolved glacier records, based on as yet unevaluated historical material, complemented with dendrogeomorphic studies will be produced for selected study sites in southern South America. Observed glacier changes will be analysed and interpreted regarding climate dynamics. These observations can be compared with recently developed, high-resolution multi-proxy temperature and precipitation reconstructions. This will allow an assessment of the spatial pattern of glacier changes in southern South America, differentiating local effects from regional or larger-scale climate dynamics.The glacier length records will be stored according to international standards in the existing database of the Global Terrestrial Network for Glaciers (GTN-G) as part of the World Glacier Monitoring Service (WGMS). Glaciers are excellent indicators for the public perception of climate change in mountainous areas, and information about ongoing glacier changes and related consequences will be provided.For the applicant, the proposed project offers a unique opportunity to work in an internationally renowned centre of competence regarding South American climate and glacier dynamics, to build on earlier work, to further develop skills in glacier reconstructions, and to form a foundation for successful future, and possibly collaborative, projects in the field.
