‘Very unhealthy’ air quality to ease in Central Pa. over weekend, but remain poor

Smoke from Canadian wildfires led to some of the worst air quality in the world in Pennsylvania this week, affecting health, especially for vulnerable groups like children and asthma sufferers. The Environmental Protection Agency predicts a slight improvement over the weekend, though conditions will still be poor. The Pennsylvania Department of Environmental Protection issued a statewide Code Purple alert, urging residents to limit outdoor activities. This situation highlights the broader issue of climate change exacerbating wildfires and their far-reaching impacts on air quality and public health.
