The International Organisation for Migration (IOM)predicts there will be somewhere between 25 million and 1 billion people [internally or externally displaced] by the effects of climate change by 2050, with 200 million the closest specific estimate. The fate of these people is a distinctly moral question for developed nations that have contributed the majority of greenhouses gas emissions for decades and continue to do so today. Are those responsible for rising sea levels responsible for those who end up underwater?
