Several chronic, non-communicable respiratory diseases are climate-sensitive based on their exposure pathways  , although climate change is not the dominant driver in all cases. Worldwide, rates of adverse health impacts associated with small particulate matter  exposure have decreased steadily due to decreasing primary emissions , while rates of adverse health impacts from ozone air pollution exposure have increased . Exposure to wildland fires and associated smoke has increased in several regions . Spring pollen season start dates in northern mid-latitudes are occurring earlier due to climate change, increasing the risks of allergic respiratory diseases  .
