Researchers at McGill University have published a new study mapping human vulnerability to climate change. In what is perhaps the cruelest of ironies, researchers found that the major negative impacts of climate change will be experienced by those populations least responsible for increasing carbon dioxide concentrations and also least capable of dealing with the impacts of climate change. This begs the question, how will those responsible for increasing emissions take responsibility for their actions if they are going to be the least effected? And further, should nations with higher emissions have some kind of differentiated responsibility in dealing with the effects of climate change? What kind of role do different ethical belief systems play? Here is a brief summary of the research.
