Spain has recently endured a 21-day heat wave, significantly impacting health across various demographics, particularly affecting poorer neighborhoods and the elderly. According to researcher Julio Diaz, the first heat wave of the year is often the deadliest due to a phenomenon known as the 'harvest effect,' where the most vulnerable individuals succumb first. Meanwhile, a third-degree heat alert has been declared in Hungary, prompting health officials to advise caution, particularly for at-risk populations. Globally, July 2024 has been recorded as one of the hottest months, with the US NOAA stating it was 0.03°C warmer than July 2023, marking 14 consecutive months of record temperatures. Extreme heat has been observed worldwide, including record temperatures in Death Valley and severe conditions across Asia, Africa, and Europe. These heatwaves underscore the urgent need for climate action as they strain health systems and exacerbate existing inequalities.
