Seoul is experiencing a record-breaking heatwave, with temperatures remaining above 25 degrees Celsius for 26 consecutive nights, marking the longest streak since weather records began in 1907. This phenomenon, known as 'tropical nights,' is also affecting other parts of South Korea, including Busan, which has tied its own record with 21 consecutive tropical nights. The prolonged heat has led residents to adopt various methods to cope, such as using ice packs and running air conditioners almost continuously. UN Secretary-General Antonio Guterres has warned of an 'extreme heat epidemic' and called for action to mitigate the impact of climate change. The heatwave is expected to continue, with no immediate relief in sight, according to weather forecasts.
