Air and water temperatures in the Delta are increasing, with heatwaves becoming more frequent and severe. Potential ecological impacts include phenological shifts, increased species invasion, and conditions that favor smaller-bodied individuals of many species. People may suffer adverse health impacts ranging from dehydration and heat exhaustion to lower birth weight, mental health problems, and increased rates of violence.
