Wildfires are growing under climate change, and their smoke threatens farmworkers, study says

As climate change increases the frequency and intensity of wildfires around the world, a new study shows that farmworkers are paying a heavy price by being exposed to high levels of air pollution. And in Sonoma County, the focus of the work, researchers found that a program aimed at determining when it was safe to work during wildfires did not adequately protect farmworkers.
