Man-made climate change accepts no boundaries and affects virtually all components of the earth (Hilty et al. 2007, Turner et al. 2009, Bush et al. 2011, Brodie et al. 2012, Resendiz 2012). The ozone hole problematic showed us already that Antarctica as the 7th continent and very remote from industrial centers, is also directly affected by such impacts of industrialization and globalization (Turner et al. 2009, Reck 2011). A wider review of Antarctica and its current ecological set-up shows such impacts and patterns as a common scheme (Convey 2001, Thomas et al. 2008, Huettmann 2011, Resendiz 2012, Summerson 2012). For instance, marine mammals were overharvested for blubber and whale meat, and when the industrial revolution started in the Northern hemisphere allowing for such pursuits and creating a demand in the first place (Huettmann 2011 for context). Antarctic seabirds show signals of global economic development, too (Resendiz 2012). Nowadays, a continued overuse is found in Antarctica in some modern fisheries and krill harvests (Constable et al. 2000, Thomas et al. 2008; see also Trivelpiece et al. 2011, FAO Fishery Statistics 2012, Ainley et al. 2012 in Huettmann 2012). This is a direct analogy to modern Antarctica tourism where people from the Northern hemisphere travel to the far south or the South Pole (International Association Antarctica Tour Operations IAATO 2012), using up a precious carbon footprint and affecting a natural resource (eg, through physical impact or through CO2 emissions from air plane travel for instance). This indeed has many implications for nature and global carrying capacity. For billions of years Antarctica has been shaped by plate-tectonics, universal cycles and the underlying climate (Thomas et al. 2008, Turner et al. 2009, Martinson 2012). But now, man-made climate change includes the rise of carbon dioxide concentration, habitat transformation and subsequent global climate change. While some areas in the world experience cooling effects or no measurable climate effects, it is still valid to state that these are part of global climate change, too. They are therefore heavily driven by mankind (Millennium Ecosystem Assessment; http://www. unep. org/maweb/en/index. aspx). The Intergovernmental Panel on Climate Change (IPCC; www. ipcc. ch) has summaristed this knowledge into its public reports, based on assigned models (Intergovernmental Panel on Climate Change 2007). This work is available now to the global public for forecasting and strategic planning of natural resource management for instance (Brodie et al. 2013). These models have already received major attention for the Antarctic (Thompson & Solomon 2002), some of its biodiversity (McClintock et al. 2008, Jenouvrier et al. 2009) and for modeling (Table 1). As a summary of these efforts, it becomes clear that wider, coherent and mutually accepted and efficient community efforts are lacking to preserve Antarctic biodiversity in earnest (Turner et al. in Turner et al. 2009, Brodie et al. 2013; but see De Broyer et al. this volume), that data qualities and methods are still developing and maturing, and that the warming impact for Antarctica is confirmed overall (some larger areas in Antarctica seem to show none or no strong environmental changes, thus far; Turner et al. 2009).
