induced alterations of nature. Therefore, climate change is often used to describe human-specific impacts, such as global warming.
Fig. 1 Worldwide knowledge about the causes of climate change A third of the world‘s population has never heard of global warming, see Fig.1 Worldwide knowledge about the causes of climate change (Gallup Poll, 2011a) and those who have heard: these figures are higher in highly advanced economies and lower in less developed economies. Respondents of developed economies in Asia, such as Japan and South Korea, rank humaninduced causes for global warming at the highest levels, strongly shared by Latin Americans. And even in those economies where a considerable number of respondents are not aware of global warming, the belief is shared that it is caused by human-induced activities, doubly ranked higher than caused by natural causes. However, the majority of the US people believes that the causes of global warming are more induced by natural causes than by human activities. There are also changes in the global assessment of being threatened by climate change, see Fig. 2 Changes in the global assessment of the personal dangers of climate change. Worldwide, there is 42 % of adults who see global warming as a threat; these results haven‘t changed very much from 2007/08 to 2010, surveyed in 111 countries in 2010 (Gallup Poll, 2011b). 44
