For instance, temperatures at upper ocean have increased from 1971 to 2010, Greenland and the Antarctic have decreased in extension, and the atmospheric concentrations of CO2 have risen by 40% since the pre-industrial period. Second, climate change has also caused ethical issues that are necessary to consider in policy-making. Currently, effects of climate change have challenged distributional fairness and environmental justice. Although international laws state that no nation has the right to harm others as mean of achieving economic health, GHG emissions have caused a global damage, specially to the least involucrate (Brown, 2004). In fact, developed countries have produced most of the GHG emissions, affecting mainly countries that slightly contribute to the problem and are the most vulnerable to weather changes (Brown, 2004). Thus, policies should encourage a common but differentiated responsibility since emission levels differ greatly and its reduction will be uneven if equity is not considered (Brown, 2004). Finally, scientific knowledge and ethical issues on climate change have fostered political actions through the development of regulations and agreements. On a national level, governments
