Climate change making haj hotter, less safe: Study
A recent study indicates that climate change is making the annual haj pilgrimage increasingly dangerous due to rising temperatures. The haj, held in Mecca, is now often conducted in conditions exceeding 40 degrees Celsius, which poses significant risks to the hundreds of thousands of pilgrims. Researchers warn that the safe window for the pilgrimage is shrinking, with extreme heat extending into historically cooler months.

- ▪The timing of the haj is governed by the Islamic lunar calendar, moving back about 11 days each year in the Gregorian calendar.
