What are the Climatic Controls on Changes in Antarctic Sea Ice?
Unlike Arctic sea ice, which is currently decreasing at a rate which may make it seasonally ice-free before the end of the 21st century (Körper et al., 2013), Antarctic sea ice (ASI) is experiencing an overall steady increase, albeit with strong regional variations (Zwally et al., 2002). Here is outlined the main climatic processes and factors which cause and control changes in ASI, studied using both climate modelling (Körper et al., 2013; Li et al., 2013; Vancoppenolle et al., 2009) and direct observations (Jacobs and Cosimo, 1997; Parkinson and Cavalieri, 2012). In general, there seems to be a large combination of factors which are causing the regional variations and overall increase in ASI, many of which are interlinked (Kwok and Cosimo, 2002; Stammerjohn et al., 2008; Yuan and Li, 2008). This report also highlights how climate models need to be tested against real-life observations to ensure accurate predictions for the future (Goosse et al., 2009; Maksym et al., 2012; Vancoppenolle et al., 2009), which are important in the face of growing concern over climate change and sea-level rise, in which ASI may play a huge part (Körper et al., 2013).
Sea ice in Antarctica is increasing as a result of many climatic factors controlling the conditions and dynamics of the continent and Southern Ocean. This report aims to outline which climatic factors or systems exert a control on Antarctic sea
