Background ozone burdens Las Vegas’ air quality in spring Background ozone burdens Las Vegas’ air quality in spring High background levels of ozone pollution make it hard for Las Vegas and other southwestern cities to meet US air quality standards in spring, two NOAA studies find. But local pollution sources drive summer's high ozone days. Read more

Study: Reducing human-caused air pollution in North America & Europe brings surprise result: more hurricanes 11May2022 Read more A new NOAA study published today in the journal Science Advances about four decades of tropical cyclones reveals the surprising result that reducing particulate air pollution in Europe and North America has contributed to an increase in the number of tropical cyclones in the North Atlantic basin and a decrease in the number of these storms in the Southern Hemisphere. The study also found that the growth of particulate pollution in Asia has contributed to fewer tropical cyclones in the western North Pacific basin. Read more
