High summer temperatures, pushed higher by global climate change, may bring with them a spike in hospitalizations for respiratory problems, according to an analysis of data from twelve European cities, from Dublin to Valencia. The data comes from the "Assessment and Prevention of Acute Health Effects of Weather Conditions in Europe" (PHEWE), a multi-center, three-year collaboration between epidemiologists, meteorologists and experts in public health collaboration that investigated the short-term effects of weather in Europe.
