Extreme Heat Threatens Major Cities: Study Reveals the World’s Most Dangerous Urban Area

Climate Hazards Facing Global Megacities

According to НВ — Техно: A scientific study released on June 12 at 10:00 PM examined climate-related risks for 220 major cities with populations exceeding one million. The findings show that over 95% of the highest-risk urban centers are located in South and Southeast Asia, as well as sub-Saharan Africa. Topping the list of the most vulnerable cities is Basra in Iraq, followed by the Indian cities of Ahmedabad and Nagpur, along with Bamako in Mali.

Other cities ranked among the most at risk include:

• Ho Chi Minh City, which placed 16th
• Cairo, in 22nd position
• Bangkok, which came in 38th

In contrast, London was identified as the least vulnerable among all evaluated cities. Projections indicate that by 2050, the proportion of people living in urban areas will reach two-thirds of the global population.

The Urgent Need for Urban Adaptation

The researchers behind the study stress that the danger goes beyond simply recording high temperatures. As Netmi Jayaratne Kariyawasam explained,

“In many Asian and African hubs, extreme heat coincides with low household incomes, aging demographics, and a lack of resources to adapt-creating a real threat to daily life and survival.”

Jesús Lizana, one of the study’s authors, emphasized that

“this work represents the world’s first tool for clearly comparing overheating risks and tracking progress in urban resilience.”

Proposed solutions for improving city safety include passive cooling technologies, expanding urban forests, and energy-efficient ventilation systems. Radhika Khosla also noted that 'widespread use of energy-intensive cooling equipment only worsens global warming, trapping us in a vicious cycle.'

The study highlights the critical importance of adapting cities to climate change and implementing new technologies to reduce overheating risks, as global warming increasingly threatens urbanized areas worldwide.

These results underscore the need for urgent action to boost urban climate resilience, particularly in high-risk regions. With urbanization accelerating, it is essential to identify strategies that reduce population vulnerability and improve living conditions in megacities. Adapting to climate change remains a key challenge for governments and local organizations, which must integrate these factors into their development plans.

Understanding the broader implications of climate change is essential, especially in light of recent findings about urban vulnerabilities. For instance, a separate study reveals how significant shifts in Antarctica have impacted global sea levels. This research offers valuable insights into the interconnectedness of climate phenomena and their effects on coastal cities.
