MAYEWSKI, Paul Andrew. State of the Antartic climate system Excerpts from SASOCS (Mayewski et al. 2009)Estado del sistema climático Antártico Extractos de SASOCS (Mayewski et al. 2009). Anales Instituto Patagonia (Chile) [online]. 2012, vol.40, n.1, pp. 25-30. ISSN 0718-686X.  doi: 10.4067/S0718-686X2012000100001.

Two recently released reports document the past, present and future predictions for climate over the Antarctic and the Southern Ocean. From these syntheses it is clear that the Antarctic plays a critical role in hemispheric to regional climate change and that in recent times human activities are beginning to have a marked impact on Antarctic temperature, precipitation, atmospheric circulation, ocean circulation, sea ice extent and chemistry of the atmosphere.
