Iowans are experiencing the very real impacts of climate change, including heavier rains in spring, increased flooding, and a longer growing season. Human health effects are just as real and are already being felt in Iowa. Most obvious, immediate, and direct are the health‐related effects of extreme events, which are increasing in frequency and severity as our atmosphere warms and holds more moisture. Iowa and the Midwest have experienced higher humidities and increased nighttime temperatures making it harder to recover from daytime heat stress. Repeated heavy rain events cause increased exposures to toxic chemicals and raw sewage that are mobilized and spread by flood waters.
