Fossil fuel pollution caused more than eight million premature deaths inaccounting for nearly 20 percent of adult mortality worldwide, researchers reported Tuesday.

Nariobis Vehicle Pollution of that grim tally was split across China and India, with another million deaths equally distributed among Bangladesh, Indonesia, Japan and the United States, they reported in the journal Environmental Research. The toxic cocktail of tiny particles cast off by burning oil, gas and especially coal was responsible for a quarter or more of the mortality in half a dozen nations, all in Asia.

Chan School of Public Health, said in a statement. The potential to avoid millions of premature deaths should be a powerful additional incentive for policymakers Nariobis Vehicle Pollution drive down greenhouse gas emissions and hasten the global shift from brown to green energy, he said. Worldwide, air pollution shortens lives by more than two years on average, earlier research has shown.

Fossil fuel pollution causes one in five deaths globally: study

Worst-hit is Asia, where average lifespan is cut 4. In some regions of these countries, life expectancy is reduced by twice as much. The new study nearly doubles previous estimates of the number of people killed by fossil fuel pollution. The World Health Organization says that air pollution -- including indoors -- Nwriobis seven Nariobis Vehicle Pollution people per year, with 4.

The most recent Global Burden of Disease study -- the most comprehensive catalogue of why people die -- advances roughly the same numbers. Both of these estimates relied on satellite data and surface observations to determine concentrations of the smallest -- and most deadly -- calibre of pollution, known as PM2. But they cannot determine whether these microparticles come from burning fossil fuels or, say, dust and wildfire smoke, according to co-author Loretta Mickley, an expert in chemistry-climate interactions at Harvard.

To get a Nariobis Vehicle Pollution fine-grained picture of where particle pollution comes from and its health impacts, Mickley and colleagues used a 3-D model of Nariobis Vehicle Pollution chemistry, known as GEOS-Chem, that divides Earth's surface into bykilometre bymile blocks. The next step was to plug in data on carbon emissions -- from the power sector, industry, shipping, aviation and ground transport -- along with NASA simulations of air circulation.

Once the researchers Nariobis Vehicle Pollution PM2. Previous calculations of air pollution impacts -- based on exposure to indoor second-hand smoke -- seriously underestimate the danger, recent studies have found, so Polluiton researchers developed a new risk assessment model. Coronary heart disease and stroke account for almost half of those deaths, with lung diseases and other non-communicable diseases such as diabetes and high blood pressure making up most of the rest.
