In 2024, the world’s top ten climate disasters incurred more than $288 billion in damages and resulted in over 2,000 fatalities. The United States was particularly affected, absorbing nearly half of the total economic cost, while five Southeast Asian nations collectively faced more than 40% of the reported casualties.
A report titled “Counting the Cost 2024: A Year of Climate Breakdown,” released by the international NGO Christian Aid, assessed the economic impacts and human losses due to significant climate-related events worldwide. The report highlighted that virtually no region was immune to devastating climate incidents this year. North America and Europe accounted for seven of the ten most expensive disasters, with additional events impacting China, Brazil, and various countries in Southeast Asia.
Many of the cost estimates reflected only insured losses, suggesting that the actual financial toll may be considerably higher, and the true human impact could also be underreported. According to the report, individuals living in poverty in low-income countries are disproportionately affected, as they typically have fewer assets, less insurance coverage, and limited access to public services.
Notably, the report does not include the deadly landslides in Wayanad, Kerala, which claimed over 200 lives in July, as these incidents were not classified among the costliest disasters due to their uninsured nature.
Among the events that caused the highest financial damages in 2024, Hurricane Milton, which struck the US in October, was the most significant, resulting in $60 billion in damages and taking 25 lives. Hurricane Helene, impacting the US, Cuba, and Mexico in September, followed closely with damages amounting to $55 billion and 232 fatalities.
The report further highlighted that the US endured numerous costly storms throughout the year, leading to over $60 billion in damages from other convective storms, which collectively resulted in 88 fatalities.
In terms of human casualties, Typhoon Yagi was particularly devastating in Southeast Asia, claiming more than 800 lives in September. The typhoon struck the Philippines before moving on to Laos, Myanmar, Vietnam, and Thailand, causing landslides, flash floods, and significant destruction to homes and agricultural land, with total damages estimated at $12.6 billion. Additionally, floods in China inflicted $15.6 billion in damages and resulted in 315 deaths during June and July.
European countries were also heavily affected, experiencing three of the ten costliest disasters. Storm Boris and floods in Spain and Germany together caused damages of $13.87 billion and resulted in 258 fatalities, with a majority of these losses occurring during the floods in Valencia in October. In Brazil, flooding in the state of Rio Grande do Sul led to 183 deaths and $5 billion in damages.
Patrick Watt, CEO of Christian Aid, emphasized the urgent need for transitioning away from fossil fuels to prevent further climate disasters and highlighted the necessity for adaptation strategies, especially in the global South, where resources are already limited and populations are most vulnerable to extreme weather events.
