air pollution

Oklahoma, Missouri and Nebraska are among dozens of states that have yet to submit plans for improving air quality in protected areas. Environmental nonprofits are suing the EPA to compel the agency to take action.

The rising number of fires hamper decades of environmental efforts, and over 40% of Americans — more than 137 million people — live in places with poor air quality, a new report says.

A new study links the epidemic of severe lung disease among coal miners to toxic silica dust. The findings echo a 2018 investigation by NPR and the PBS show Frontline.

"We see a really clear association between how these maps were drawn in the '30s and the air pollution disparities today," says an author of a study on the effects of the discriminatory policy.

Air pollution has traditionally been measured by the size of particles, which tend to be larger in urban areas than in rural ones. But a new study from the University of Illinois suggests that the toxicity of air in rural areas is just as bad as in urban ones.

The number of days cities across the country are facing air pollution from fires has gone up dramatically.

Lava has been flowing since Sept. 19 and has just reached the Atlantic Ocean. When the lava spills into the sea, it can create toxic gas; officials told residents to seal their windows and doors.

Tens of millions of Americans are forced to live with wildfire smoke now every year. New research shows that it's more invasive than previously thought, infiltrating homes, schools and offices.

Eastern states have been clouded in a smoky haze for days, and with the smoke comes poor air quality. People far away from the fires aren't ready for the breathing problems the smoke brings.

The U.S. plans to reduce greenhouse gas emissions dramatically in the next decade. Scientists say it's crucial that the U.S. succeed. Still, many of the positive effects won't arrive for decades.
