Unprecedented Heat Turns Mecca Pilgrimage Deadly: More Than 500 Dead This Year

The annual Hajj pilgrimage, a significant religious event drawing millions of Muslims to Mecca, Saudi Arabia, has turned deadly due to unprecedented heat exacerbated by climate change. 

Recent studies by Climameter highlight the direct link between climate change and the significant increase in temperatures during the pilgrimage, resulting in the deaths of thousands of pilgrims.

The extreme heatwave that swept across large parts of the Eastern Mediterranean and the Middle East in recent weeks coincided with the Hajj, leading to tragic consequences. 

On Tuesday, temperatures in Mecca soared to a staggering 47ºC. Media reports indicate that at least 550 pilgrims from various countries succumbed to heat-related illnesses during the pilgrimage. 

Among the deceased were 323 Egyptians, 98 Indians, 60 Jordanians, and five Iranians, illustrating the wide-ranging impact of this climate-induced disaster.

Climameter, an EU-funded initiative that conducts rapid analyses of climate change's role in extreme weather events, found that the extreme heat during this year’s Hajj was intensified by 2.5ºC due to climate change. 

Using satellite data from the past 40 years, Climameter compared meteorological systems from the late 20th century (1979-2001) to recent decades (2001-2023). 

Their findings reveal that today's heatwaves are up to 2.5°C more intense than those at the turn of the century.

Davide Faranda, a Climameter researcher at CNRS, France, emphasized the urgency of addressing climate change to prevent future tragedies. 

"ClimaMeter's report highlights that the deadly heat during this year's Hajj is directly linked to fossil fuel burning and has affected the most vulnerable pilgrims. Immediate action is imperative to safeguard the health and safety of Middle East citizens and pilgrims. Only reducing fossil fuel combustion can prevent reaching critical temperature thresholds and avoid transforming these significant religious events into recurrent tragedies," Faranda stated.

Tommaso Alberti, a Climameter researcher at INGV, Italy, added, "ClimaMeter's analysis indicates that natural climate variability is highly unlikely to be the main cause of the Saudi Arabian heatwave, with up to 2.5°C warmer than the warmest heatwaves previously observed in the region."

Johnny White, a lawyer at ClientEarth, remarked on the broader implications of the climate crisis. "The climate crisis is the greatest threat to human rights globally. Loss of life and harm to people's wellbeing will only increase if systemic emitters don't rapidly rein in the fossil fuels driving dangerous heat spikes and other extreme weather events," he said. 

White also highlighted a significant legal development, noting that the UN recently warned Saudi Aramco over its role in driving climate-fuelled human rights violations. 

"The UN was clear: human rights law demands corporate action on climate change. 

Unless they tackle their emissions and stop recklessly expanding oil and gas, major polluters like Saudi Aramco will continue to exacerbate the suffering caused by rising temperature extremes in Saudi Arabia, across the Gulf, and around the world," 

he continued. White concluded by pointing out that financial companies supporting fossil fuel giants are also at risk of breaching human rights standards.

The findings underscore the urgent need for global action against fossil fuel combustion to mitigate future tragedies during significant religious events like Hajj. 

Addressing climate change is essential for protecting vulnerable populations from extreme weather conditions. 

As temperatures at Mecca's Grand Mosque reached a scorching 51.8 degrees Celsius, the devastating impact of the heatwave became tragically apparent, with the death toll continuing to rise.

In conclusion, the deadly heatwave during this year’s Hajj pilgrimage is a stark reminder of the urgent need to combat climate change. 

The loss of thousands of lives highlights the critical importance of reducing fossil fuel emissions and implementing measures to protect vulnerable populations during extreme weather events. 

The world must act now to prevent such tragedies from becoming a recurring nightmare.
