  "summary": "A new study predicts that by the end of the century, a hot day could have an extra four hours of extreme heat if high emissions continue, potentially totaling eight hours of extreme heat per day. This research, conducted by scientists from China's Sun Yat-sen University and Southern Marine Science and Engineering Guangdong Laboratory, highlights the limitations of daily temperature metrics in capturing short but significant periods of extreme heat. The study, published in Nature Climate Change, emphasizes the disproportionate impact on low and middle-income countries, where over three-quarters of current heat exposure and future increases in lifetime exposure are expected to occur. The researchers advocate for the use of hourly assessments to enhance heat risk management and public health planning, noting that global hourly data shows a marked increase in extreme heat events, with a sixfold rise in population exposed to such conditions under a high-emissions scenario.",
