We’re just days away from turning the page from summer to fall. Drought in the United States expanded and intensified in Summer 2023, largely influenced by not only lack of precipitation, but extreme heat and evaporative demand. While the number and size of wildfires were relatively small in the western U.S. compared to recent summers, unhealthy levels of smoke still poured into the contiguous

As with many other climate-related disasters, drought can lead to negative health outcomes. The significant impacts that drought can have on respiratory illness, such as bronchitis, Chronic obstructive pulmonary disease (COPD), and asthma, are of particular concern. Drier conditions can increase dust, smoke, and other particulate matter, contributing to reduced air quality that exacerbates these
