Recent studies highlight the escalating impact of climate change on global heat-related health issues. A UTSA study shows a 117% increase in U.S. heat-related deaths from 1999 to 2023, with 2023 having the highest number of deaths (over 2,300) primarily affecting outdoor workers, children, the elderly, and the unhoused, especially in the Southwest. A World Resources Institute analysis projects severe increases in heat wave frequency and duration in major cities if global temperatures rise by 3°C. Another study links air pollution and rising temperatures to a surge in strokes, with nearly 12 million annual cases globally. Furthermore, Climate Central reports that 2 billion people experienced over 30 days of health-threatening temperatures between June and August 2024, largely due to fossil fuel emissions. Overall, these findings underscore the urgent need for comprehensive climate action and adaptive public health strategies to mitigate the rising risks.
