South Korea Records Its Highest Ever Temperature

South Korea recorded its highest temperature since modern observations began in 1904, with the city of Yangsan reaching 42.5C as temperatures exceeded 40C for a fifth consecutive day. Authorities warned residents to "immediately stop all outdoor activities." The Guardian reports: More than 20 localities in South Korea were under emergency heatwave alerts on Sunday -- a new warning category introduced this year to better address rising temperatures. An emergency alert is issued when areas experiencing a heatwave are forecast to hit perceived temperatures of 38C or an actual temperature of 39C for the day. Issuing a heat warning, the weather agency urged people to "immediately stop all outdoor activities," adding that "indoor spaces without air conditioning are dangerous." "Move immediately to a cool place, such as a designated cooling centre or a shaded area, and stay hydrated while resting," it advised. Fearing for those people most vulnerable to heat, the prime minister, Han Seong-sook, ordered local officials to strengthen safety checks on residents and to ensure a stable power and water supply was maintained. [...] Korea Meteorological Administration (KMA) data show the average annual number of heatwave days in the country has more than doubled to 19 in the past five years.
