Coal Emissions in China Slash 5.5 Years off Life Expectancy, Study Says
2013-07-09 18:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: The life expectancy of people living in northern China is 5 ½ years less than in southern China as a result of the north's notoriously bad air pollution, largely due to the burning of coal, according to a new study. In an analysis of air quality recordings from 90 Chinese cities from 1981 to 2000 and mortality data from the 1990s, a team of researchers estimated that high air pollution will cost the roughly 500 Getty Images million people living north of the Huai River a combined 2.5 billion...
Northern China's air pollution reduces life expectancy by 5.5 years
2013-07-08 21:03:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Air pollution causes people in northern China to live an average of 5.5 years shorter than their southern counterparts, according to a study released on Monday which claims to show in unprecedented detail the link between air pollution and life expectancy. High levels of air pollution in northern China much of it caused by an over-reliance on burning coal for heat will cause 500 million people to lose an aggregate 2.5 billion years from their lives, the authors predict in the study, published...
