CLIVASH2k - Climate variability in Antarctica and Southern Hemisphere in the past 2000 years


CLIVASH2k timeline

 May 2017  2018  2019  2020  2021



The CLIVASH2k project aims to improve our understanding of large scale modes of climate variability and the mechanisms and drivers of climate change in Antarctica, the sub-Antarctic and the wider Southern Hemisphere during the past 2000 years. We will build upon previous PAGES syntheses documenting changes in Antarctica over the past 1000-2000 years to focus on the mechanisms driving climate variability.

We plan to address how large-scale modes of atmospheric circulation, such as the Southern Annular Mode (SAM) and the Interdecadal Pacific Oscillation (IPO), influence the climate in Antarctica and the Southern Hemisphere on a regional scale.

We aim to:

(i) enhance current understanding of the dominant modes of variability in each region and whether it is possible to tease out the influence of large-scale changes from local drivers

(ii) produce a multi-proxy reconstruction of climate modes and assess how they have influenced regional climate variability over the past 2000 years.
