Nearly 2 million Muslims will reach the end of the haj pilgrimage this week, but extreme heat has proved fatal for hundreds who began the journey last Friday to the Kaaba at the Grand Mosque in Mecca in Saudi Arabia.
At least 562 people have died during the haj, according to a Reuters tally based on foreign ministry statements and sources.
Egypt alone has registered 307 deaths and another 118 missing, medical and security sources told Reuters, as temperatures at times soared past 51 degrees Celsius (124 Fahrenheit).
“It was so harsh and the people cannot bear that type of heat,” said Wilayet Mustafa, a Pakistani pilgrim.
A witness said bodies lay on the side of the road near Mina, just outside Mecca, covered with the white Ihram cloth – a simple garb worn by pilgrims – until medical vehicles arrived.
Climate scientists say such deaths offer a glimpse of what is to come for the tens of millions of Muslims expected in coming decades to undertake the haj.
Integral parts of the haj, Schleussner said, such as the ritual climb of Mount Arafat, have become “incredibly dangerous to human health.”
SITUATION WILL WORSEN
The timing of the haj is determined by the lunar year, which sees the pilgrimage move back by 10 days annually. While the haj is now moving towards winter, by the 2040s it will coincide with the peak of summer in Saudi Arabia.
“It is going to be very fatal,” said Fahad Saeed, a climate scientist at Climate Analytics based in Pakistan.
Heat-related deaths along the haj are not new, and have been recorded back to the 1400s.
A lack of acclimatization to higher temperature, intense physical exertion, exposed spaces, and an older population makes pilgrims vulnerable.
