30 Heat Deaths Surpass Full-Year 2025 Total; President Declares National Climate Disaster
KDCA data showed cumulative heat-illness deaths reaching more than 30 by August 10, exceeding the full-year 2025 final count of 29. Cumulative patients stood at 3,320, with more than 200 people collapsing on some single days in August. President Lee Jae-myung chaired a Central Disaster and Safety Situation Room meeting, officially designating heatwaves a national climate disaster, and ordered measures protecting elderly people living alone and outdoor workers as well as power-grid and housing infrastructure improvements to be included in next year's budget. 62% of deaths involved people aged 80 or older. Analysis showed that compound climate disasters involving both extreme rain and extreme heat occurred 4.8 times more frequently and were 3 times more intense over the past four years compared with the 1991–2020 average.
