California Wildfire Nears Sierra National Park

A wildfire in California approached the Sierra National Park on September 9, 2025. The fire has raised concerns for wildlife and park infrastructure. Firefighting teams are actively containing the blaze.

Study links wildfires and heat to worse air quality in megacities

A recent study highlights how increasingly frequent wildfires and heat events are aggravating air pollution in major urban areas. Researchers found that these climate-driven factors significantly elevate levels of harmful particulates and ozone. The findings underscore the growing environmental challenges for densely populated cities.

The U.S. Forest Service has launched the Plumas Community Protection project to safeguard 285,000 acres of Northern California's Plumas National Forest from megafires through thinning, logging, and prescribed burns. Funded by $274 million from Congress in 2023, the initiative aims to build forest resilience following the devastating 2021 Dixie Fire. However, progress has been slow amid bureaucratic challenges and limited transparency.

Scientists simulate wildfire-induced thunderstorms in climate models
