The Climate Risk Index ranks countries based on the human and economic toll of extreme weather. From 1993 to 2022, more than 765,000 lives were lost due to climate-related disasters, while direct economic losses totaled nearly $4.2 trillion (inflation-adjusted).
For three decades, Asia has been at the frontline of climate-related devastation, suffering at least $2 trillion in damagesdue to extreme weather events, according to the latest Climate Risk Index (CRI) survey. From floods and typhoons to heat waves and droughts, the economic and human toll continues to rise, underscoring the urgent need for stronger climate resilience.
RELEVANT SUSTAINABLE GOALS
China leads the region in economic losses and fatalities, having spent $1.32 trillion on disaster response and recording 42,000 deaths since 1993. Other nations, including Myanmar, India, and the Philippines, have also endured catastrophic events, with high-income countries not entirely shielded from climate damage.
David Eckstein, senior advisor of climate finance and investments at Germanwatch, noted that climate science has long predicted these patterns. “Climate change increases the risk for both countries affected by highly unusual extreme events as well as those impacted by recurring disasters. What was once rare is becoming the new normal,” he said.
China, India, and the Philippines: The Most Affected Nations
The Climate Risk Index ranks countries based on the human and economic toll of extreme weather. Over the past 30 years, some of the world’s largest economies—China, India, and the Philippines—have borne the brunt of climate-induced disasters.
- China: The country has spent $1.32 trillion responding to climate disasters, with 42,000 deaths recorded due to extreme weather. Flooding remains the most significant threat, with major cities struggling against rising sea levels and changing monsoon patterns.
- India: More than 400 extreme weather events, including floods, heatwaves, and cyclones, have caused nearly $600 billion in damages and resulted in 80,000 fatalities since 1993.
- Philippines: Known as the most climate-vulnerable nation in Southeast Asia due to its geographical location, the Philippines has endured $70 billion in losses. Typhoon Haiyan, one of the strongest cyclones in recorded history, killed over 7,000 people and destroyed more than one million homes.
Despite high-income countries having stronger infrastructure, they are not immune. Countries like Japan and South Korea have also experienced rising climate-related costs, highlighting the global scale of the climate crisis.
The Rising Frequency of Extreme Weather Events
The latest Climate Risk Index 2025 report provides a stark reminder of how climate inaction is translating into higher human and economic costs. From 1993 to 2022, more than 765,000 lives were lost due to climate-related disasters, while direct economic losses totaled nearly $4.2 trillion (inflation-adjusted).
The report warns that extreme weather events are not only increasing in frequency but also in intensity. Heatwaves, wildfires, and severe storms are no longer isolated phenomena—they are becoming more devastating with each passing year.
The Case for Climate Adaptations
Despite the grim statistics, there are successful climate adaptation strategies that have significantly reduced disaster-related casualties.
One striking example is Bangladesh, which has cut its cyclone-related mortality rate by more than 100-fold in the last 40 years. David Eckstein, co-author of the CRI report, emphasized the importance of adaptation efforts, stating, “The case of Bangladesh proves that proactive measures can drastically reduce climate-related losses. But this requires financial support from the international community as well as strong national policies that prioritize risk reduction.”
Adaptation strategies include:
- Early warning systems to alert communities before disasters strike
- Stronger flood defenses to protect major urban centers
- Sustainable infrastructure designed to withstand extreme weather
However, many developing nations still lack the financial resources and technical capacity to implement these measures, placing them at greater risk.
The findings of the Climate Risk Index 2025 should serve as a wake-up call. The world is moving toward a new climate reality where extreme weather events are no longer sporadic but a constant threat.
With climate-related disasters costing the world trillions and human casualties continuing to mount, the urgency for international cooperation on climate adaptation and mitigation has never been greater.
For Asia, the choice is clear: invest in climate resilience now or pay an even greater price in the future.
