Concurrent heat waves, air pollution exacerbate negative health effects of each

The combination of prolonged hot spells with poor air quality greatly compounds the negative effects of each and can pose a major risk to human health, according to new research from the University of California, Irvine.“The weather factors that drive heat waves also contribute to intensified surface ozone and air pollution episodes,” said UCI professor of Earth system science Michael J. Prather, co-author of the study, published this week in Proceedings of the National Academy of Sciences. “These extreme, multiday events tend to cluster and overlap, worsening the health impacts beyond the sum of their individual effects.”

Canadian glaciers now major contributor to sea level change, UCI study shows

Ice loss from Canada’s Arctic glaciers has transformed them into a major contributor to sea level change, new research by University of California, Irvine glaciologists has found.From 2005 to 2015, surface melt off ice caps and glaciers of the Queen Elizabeth Islands grew by an astonishing 900 percent, from an average of three gigatons to 30 gigatons per year, according to results published today in the journal Environmental Research Letters.
