Antarctic Surface Mass Balance (SMB) since 1900. Outcome from Antarctica 2k regional working group. Figure 9 from Thomas et al. (2017) Antarctic regional snow accumulation over the past 1000 years, doi:10.5194/cp-2017-18.

CLIVASH2k will build upon the PAGES regional networks (Antarctica2k, LOTRED-SA and Aus2k) to investigate southern hemisphere climate variability over the past 2000 years. We will explore the links and teleconnections between mid and high-latitudes through the assimilation of a range of proxy archives, such as ice cores, lake sediments, ocean sediments, and peat records, from Antarctica, the sub-Antarctic and the wider Southern Hemisphere.

The aims of this working group are:

- To enhance our understanding of Antarctic, sub-Antarctic and Southern Hemisphere climate variability over the past 2000 years.

- Evaluate the key drivers of Southern Hemisphere climate variability on regional to hemispheric scales.

- Work towards a community based multi-proxy reconstruction of key modes of variability over the past 2000 years and how they relate to climate in Antarctica, the sub-Antarctic and the wider Southern Hemisphere.
