Impact & Risks

The unseasonable heat poses health risks, particularly for vulnerable populations such as the elderly and those with pre-existing conditions. Infrastructure like cooling shelters may not be readily available during fall months, increasing the risk of heat-related illnesses. Prolonged exposure to high temperatures can also strain the body, especially after a long summer of heat. Additionally, the influx of humid air could exacerbate discomfort and health risks for residents. Researchers have observed that such out-of-season heat events are becoming more frequent globally, including in the United States, due to climate change.
