In 2006 we formed the multidisciplinary research consortium ‘Millennium’ to investigate European climate change within the context of the last 1,000 years. Expanding from this consortium we encourage submissions on late Holocene palaeoclimates from around the world. Millennium is grounded in the rationale that a multi-proxy approach represents one of the most powerful methods to improve our understanding of past regional and global climate variability and we welcome posters and papers around, but not limited to, Millennium's core research themes: documentary and historical climate records, tree ring proxy data, sedimentary archives (peat, ice, lake sediments), marine proxies and data analysis innovations (new methods, climate modeling and proxy-model comparisons). We are particularly interested in studies involving proxy data-climate model inter-comparisons at global and regional scales.
