South Korean President Lee Jae Myung ordered an all-out government response Thursday to combat a record-breaking heatwave across the country [1].

The emergency measures aim to minimize further casualties as temperatures are expected to soar to historic levels, threatening public health and infrastructure [1].

Official reports indicate the death toll from heat-related illnesses has risen to 21 people [3]. While some reports previously cited lower figures ranging from 16 to 19 deaths, the most recent data confirms the higher toll [2, 3].

Medical facilities have seen a surge in patients, with more than 2,400 people treated for heat-related illnesses [4]. The crisis is most acute in the capital, where the forecast temperature in Seoul is expected to reach 39°C (102°F) [1].

President Lee directed government agencies to prioritize the protection of vulnerable populations. The administration is coordinating emergency services to ensure that cooling centers and medical resources are accessible to those at highest risk, particularly the elderly and those without air conditioning [1, 2].

The government response includes heightened monitoring of power grids to prevent blackouts caused by the spike in electricity demand for cooling. Officials said the priority is to prevent further loss of life during the peak of the thermal event [1].

Local authorities in Seoul have issued warnings urging residents to avoid outdoor activities during the hottest parts of the day. Emergency teams are currently deployed to high-risk areas to provide immediate assistance to citizens suffering from heat exhaustion [1, 2].

The escalation to an 'all-out' response suggests that existing public health infrastructure in South Korea was insufficient for the intensity of this specific weather event. The disparity in early death toll reports indicates a rapidly evolving crisis, while the high volume of medical treatments signals a systemic strain on the healthcare system during extreme climate events.
