International study finds intensifying desert dust episodes in Europe

A new international study published in the journal Nature, involving researchers from The Cyprus Institute, reports that desert dust episodes in Southern Europe and the Eastern Mediterranean are intensifying. Researchers link this trend to climate change, specifically citing increased drought and desertification in North Africa, as well as shifts in atmospheric circulation. Southern Europe experiences approximately 46 such events annually, which significantly impact air quality. According to the study, transported dust accounts for about one-third of the annual mean PM10 pollution limit set by the World Health Organization. High concentrations of dust are associated with adverse health outcomes, including a 0.67% increase in daily mortality and a 2.5% rise in respiratory hospitalizations among children. The findings emphasize that climate change is negatively affecting air quality beyond its traditional impact on temperature and extreme weather. Experts advocate for better adaptation and preparedness to mitigate these health risks and improve air quality management in the region.
