Modelling studies highlight the urgent need to improve air quality in cities and reduce exposure to pollution, particularly among children and the elderly.

Carbon dioxide (CO2) levels today are higher than at any point in the past 800,000 years or more.

Even while skies are clearing over China, one type of particulate pollution continues to cause problems.

Nearly 2 million new cases of pediatric asthma every year may be caused by a traffic-related air pollutant—a problem particularly important in large cities around the world—according to a new study published by George Washington University Milken Institute School of Public Health researchers.

Large wildfires and severe heat events are happening more often at the same time, worsening air pollution across the western United States, a study led by Washington State University researchers has found.

Climate change and air pollution are two major societal problems. 

Dairy farmers in the Northeast — facing a warming climate that exacerbates nutrient pollution but lengthens the growing season — can reduce the environmental impact of their operations and maximize revenues by double cropping and injecting manure into the soil, rather than broadcasting it.

New CU Boulder study: iodine from desert dust can decrease air pollution but could prolong greenhouse gas lifetimes

Researchers could show a clear correlation between the level of air pollutants and the concentration of pollutants in the leaves.

When snow and ice melt, road salt goes with them, washing into lakes, streams, wetlands and groundwater.
