San Antonio
United States
San Antonio is projected to face a future characterized by extreme heat and dangerous heat extremes. As climate change progresses, average temperatures in the area will rise, leading to an increase in the frequency and severity of heat events. These dangerous heat extremes are expected to affect public health, especially vulnerable populations such as the elderly and individuals with existing health issues. Furthermore, the increased demand for cooling is likely to place additional pressure on the city's infrastructure and energy resources, potentially resulting in higher costs and increased strain on the power grid. Ongoing monitoring and assessment of these climate risks will be essential to understand their impacts and enable appropriate measures to address the challenges ahead.
