A deadly heatwave during the Hajj pilgrimage in Saudi Arabia resulted in many deaths, predominantly among unregistered pilgrims who lacked access to cooling facilities.
Temperatures in Mecca exceeded 125°F, causing over 1,300 deaths, mostly among unregistered pilgrims.
Unregistered pilgrims, often swindled by unofficial travel agents, faced denial of access to cooling centers.
Saudi efforts to mitigate heat, such as surface-cooling coatings and misting systems, proved insufficient.

"I can’t breathe and I feel like I’m going to get sunstroke while sitting in the tent. I don’t know where to go."

Why this matters:
This disaster is a stark reminder of the escalating impact of climate change on global health and safety. Extreme heat events are becoming more frequent and intense, posing severe risks, particularly in regions accustomed to high temperatures but not prepared for such extremes. For Saudi Arabia, a country that has traditionally handled large crowds during the Hajj, the incident calls for a reassessment of strategies to manage environmental hazards and ensure the safety of all pilgrims.
As thousands of devout Muslims flock to Islam's holiest sites in Saudi Arabia for the annual Hajj pilgrimage this week, scientists warn the sacred rite is under threat due to deadly rising heat.
A Climate Analytics study found that devout Muslims in Saudi Arabia risk heat stroke not just from rising temperatures – already 36 to 43C – but also from more humidity, which prevents sweat evaporating
