Inside Climate News | Environmental groups have sued after the Trump administration ended a federal fenceline monitoring program that documented excessive carcinogenic emissions, including benzene, at coke oven facilities, arguing the rollback leaves frontline communities exposed to hazardous air pollution.

EurekAlert! | A new study using a custom-built drone with low-cost sensors found unexpectedly high PM2.5 concentrations up to 100 metres above Delhi, revealing that current models may underestimate urban haze levels and offering a scalable tool to improve air pollution forecasting and mitigation.

TechCrunch | The Trump administration’s EPA is reportedly preparing to repeal the 2009 “endangerment finding” that underpins federal greenhouse gas regulations, a move likely to trigger lawsuits, reshape U.S. climate policy, and create regulatory uncertainty for industries such as automakers.

Newsweek | Air quality alerts were issued for parts of Alaska, Pennsylvania, and Alabama on February 10 after PM2.5 levels reached “unhealthy” categories, prompting officials to advise residents to limit outdoor activity and reduce exposure to hazardous fine particle pollution.

U.S. News & World Report | A new study finds that living in neighborhoods with high levels of particle air pollution raises health risk by 48%, with combined exposure to damp housing and polluted air further compounding the danger.

Daily Mail | Air quality alerts were issued across parts of Pennsylvania, Georgia, Alabama, and Oklahoma after wildfire smoke and high-pressure stagnant air drove PM2.5 levels into “unhealthy” ranges, prompting officials to urge residents to stay indoors and limit exposure.
