Climate change exposes millions of Hajj pilgrims to deadly heat for increasingly longer parts of the year
Temperatures in #SaudiArabia are rising earlier in the year and reaching more dangerous extremes, making the pilgrimage increasingly hazardous not only in the summer months, where in 2024 more than 1300 pilgrims lost their lives when #Hajj started in mid-June temperatures reached 51°C, but even during the spring months.
In a super-rapid study researchers from World #WeatherAttribution show that for pilgrims who spend 20–30 hours outdoors, often walking in dense crowds, the risk of heat exhaustion and heat stroke is becoming far more severe earlier in the year, with temperatures now reaching heights in May that were only seen in June to August in the 1960s and 1970s, due to human-induced #ClimateChange.
