SEOUL: South Korean President Lee Jae Myung urged authorities on Tuesday (Aug 4) to step up support for people affected by a record heatwave in the country, saying the death toll had risen to 16 and warning that extreme weather was becoming more frequent. "We need to make efforts for a fundamental overhaul of the national crisis system, since this extreme weather is becoming normal," he said. The Korea Meteorological Administration also issued its first-ever heatwave warning for parts of Seoul and neighbouring Gyeonggi on Monday, extending this to all of the capital on Tuesday. The capital was under a "severe heatwave warning" Tuesday for the first time since the new category was introduced this year to alert citizens to increasing extremes. Scientists say volatile weather events are becoming more intense and frequent owing to climate change, which is man-made.
