#GreatAntarcticClimateHack will be held October 9-12, 2017 at the Scripps Institute of Oceanography Forum, La Jolla, CA. Our first-ever Climate Hack will focus on bringing Antarctic and Southern Ocean observations to bear on evaluating the latest generation of climate and earth system models, producing new climate model metrics for the 21st century.

#GreatAntarcticClimateHack is a workshop to train non-modeling experts to use observational datasets to interrogate CMIP model results, thereby creating new model metrics and validation tools. The aim of the workshop is to facilitate preparation for the next IPCC report for a much broader science community, increase non-traditional climate modeling publications, and learn to apply/utilize data sets that help develop model validation skills. This first workshop will accommodate 50 participants on site, and 50 participants to join remotely online.

Theme 3 workshop: Earth System Model Projections of the Role of Antarctica and the Southern Ocean in the Global Climate of the 21st Century

A SCAR AntClim21 Workshop - August 27 -28, 2016 - Kuala Lumpur, Malaysia

Workshop Motivation and Objectives:  This workshop, organized by AntClim21, aimed to deepen our understanding of how climatic changes over Antarctica and the Southern Ocean will impact the rest of the globe.  In particular the aim of the workshop was to strengthen communication and collaboration across traditional disciplinary boundaries to facilitate the exchange of results from recent studies and discuss the most promising directions for future research.
