Climate change may increase the number of air pollution-related deaths globally by 60,000 in 2030 and 2,60,000 by the end of this century, if left unaddressed. <br/><br/>The study by researchers at University of North Carolina at Chapel Hill in the US adds to growing evidence that the overall health effects of a changing climate are likely to be overwhelmingly negative. <br/><br/>Researchers said, it is also the most comprehensive study yet on how climate change will effect health via air pollution, since it makes use of results from several of the world's top climate change modelling groups. <br/><br/>Researchers said, in addition to exacerbating air pollution-related deaths, climate change is expected to affect health through changes in heat stress, access to clean water and food, severe storms and the spread of infectious diseases. <br/><br/>The study was published in the journal Nature Climate Change.
