Heat waves and wildfire smoke are expected to converge across the United States, creating significant health risks. Climate change is pushing global temperatures to unprecedented levels, leading to more frequent days of intense heat and pollution.
Extreme heat can trap polluted air, preventing its dissipation. Concurrently, wildfires, intensified by climate change, release smoke into the atmosphere. This undermines decades of progress in air quality improvement in certain areas of the United States.
Regulatory changes have also played a role. The rollback of environmental regulations by recent administrations has weakened controls on emissions from power plants and vehicles. This might increase the presence of pollutants like carbon dioxide, sulfur dioxide, and particulate matter. Orders to extend the operation of older coal plants further contribute to pollution. As a result, coal emissions in the U.S. rose last year, reversing previous declines.
The combined effect of extreme heat and air pollution can severely impact public health, experts warn. It magnifies the risks, underscoring the importance of addressing these environmental challenges.
