Extreme heat rarely occurs in isolation. It often interacts with other hazards “such as drought, air pollution, and wildfires” resulting in greater risks to human health, infrastructure, and the economy. This webinar will highlight NOAA-supported research that has advanced our understanding of these compounding and cascading impacts of extreme heat. Speakers will share new insights on: how drought conditions intensify heat waves and increase exposure to extreme temperatures; how heat and humidity influence air quality and particulate matter formation; and how communities are strengthening household-level health protections during overlapping heat and wildfire smoke events.
