Climate Change and Wildfires

Climate change is causing more frequent and severe wildfires. Drought and frequent heatwaves dry out plants and dirt and create fuel for fires. During a fire, smoke can travel hundreds of miles. In LA County, wildfire smoke in urban areas can significantly worsen air quality.
