When faith meets a melting point: New study warns Hajj pilgrimage is breaching human survivability limits

A new study warns that climate change is creating serious and growing risks for millions of pilgrims performing Hajj, with extreme heat and humidity already pushing human physiological limits during the 2024 pilgrimage. This research, led by Atta Ullah and his team from the Weather and Climate Services, Islamabad, Pakistan and Climate Analytics, Berlin, Germany respectively, suggests that, without urgent adaptation and global climate mitigation, the world's largest religious gathering could become increasingly dangerous in the decades ahead.
