Lack of dust makes China’s air pollution much worse

Image copyright Getty Images Image caption Studies suggest that the deaths of 1.6 million people a year in China are linked to air quality Airborne dust is normally seen as an environmental problem, but the lack of it is making air pollution over China considerably worse. A new study suggests less dust means more solar […]
