Think Global Health | A pioneering emissions trading scheme (ETS) in Surat, India, reduced industrial particulate pollution by up to 30%, proving that market-based approaches can outperform traditional regulation—offering a cost-effective, scalable model for cleaner air without hindering economic growth in developing nations.

Phys.org | Canada’s 2025 wildfire season is once again sending hazardous smoke across North America, but a new satellite-based system using NASA’s TEMPO and NOAA’s GOES-R now enables 3D tracking of smoke plume height—helping scientists distinguish between high-altitude smoke and ground-level pollution to better assess health risks and improve air quality alerts.

ScienceDirect.com | A deep neural network model accurately predicted PM2.5 levels in Seoul, with SHAP and Vanilla Gradient analysis revealing ammonium (NH₄⁺) and nitrate (NO₃⁻) as dominant contributors—especially during high pollution events—highlighting the role of secondary formation and demonstrating the value of dual explainable AI methods for model interpretation.

Post Bulletin | Rochester’s Air Quality Alliance has installed 19 monitors—with more coming—to better track local pollution, aiming to fill data gaps, inform public health, and support future policy as wildfire smoke and urban development raise air quality concerns across the region.

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.
