The Conversation | A new satellite method using NASA’s TEMPO and NOAA’s GOES-R data now allows scientists to track wildfire smoke in 3D, helping distinguish high-altitude plumes from dangerous ground-level pollution—offering more precise air quality forecasts as wildfire risks and health impacts rise across North America.

NBC10 Philadelphia | Wildfire smoke from Canada pushed air pollution in the Philadelphia region to Code Red levels on July 26, 2025, prompting health warnings and disruptions, though overnight rain helped improve conditions by Sunday morning.

ScienceDirect.com | A new hybrid AQI forecasting framework—STL-TimesNet-iTransformer-CPO—uses STL decomposition, TimesNet for long/seasonal patterns, an improved Transformer for residuals, and CPO for auto hyperparameter tuning, consistently outperforming state-of-the-art baselines in single- and multi-step predictions across extensive tests.

Kirkland & Ellis LLP | President Trump’s One Big Beautiful Bill Act significantly reshapes U.S. environmental policy by rescinding billions in unspent Inflation Reduction Act funds for air pollution, climate justice, and greenhouse gas reduction, while introducing a pay-to-expedite NEPA review system that accelerates project approvals but weakens oversight.

CBC | Scientists warn that wildfires in Manitoba may be releasing toxic metals long stored in peat-rich soils contaminated by historical mining, raising concerns about the health risks of wildfire smoke and the urgent need for expanded air quality monitoring and research.

The Guardian | A yearlong study of nearly 500 UK classrooms found that most indoor air pollution comes from outside, especially on high-smog days, and that closing windows doesn’t help—only outdoor air quality improvements and filtration can meaningfully reduce exposure for students.

NPR | The Trump administration is seeking to repeal the EPA’s 2009 endangerment finding that underpins U.S. climate regulations, a move critics say prioritizes fossil fuel interests over science and public health while setting the stage for a long legal battle.

Appalachian Voices | Residents of Institute, West Virginia — a historically Black community long exposed to industrial pollution from nearby chemical plants — are turning to grassroots air monitoring networks and environmental advocacy to fight for accountability, public health, and environmental justice amid continued resistance from industry and lawmakers.

Newsroom | UCLA | UCLA researchers have launched a new air quality monitoring network across West Los Angeles to track both fine and coarse pollutants stirred up by wildfire recovery and reconstruction, offering real-time data to help protect residents and workers.

ScienceDirect.com | A study in Delhi found that indoor air pollution, especially ultrafine particle concentrations, significantly increases during festival activities like fireworks and cooking, posing heightened health risks due to toxic particles ranging from 10 to 1000 nanometers in size.
