Global Climate Disasters Cause $120 Billion in Losses in 2025
Global Climate Disasters Cause $120 Billion in Losses in 2025
……..
A recent international report has revealed that 2025 ranked among the costliest years for climate-related disasters, with ten major events—including wildfires, hurricanes, floods, and widespread drought—across four continents causing estimated economic losses of approximately $120 billion. Experts emphasized the increasing role of climate change in intensifying these extreme events.
The report, published by Christian Aid using data from the insurance firm Aon, highlighted that 2025 saw some of the world’s most expensive climate disasters. These included wildfires in Los Angeles, deadly storms in Southeast Asia, floods in China, India, and Pakistan, as well as several powerful hurricanes. Researchers noted that these events illustrate the growing financial and human toll of extreme weather linked to global warming.
Los Angeles wildfires, which erupted in January, were the most costly disaster of the year, claiming 31 direct lives. A subsequent study in August attributed an additional 400 deaths to secondary effects such as air pollution and delayed access to medical care. Experts said climate change significantly amplified the severity of these fires, with total losses surpassing $60 billion.
Severe storms and floods in southern and southeastern Asia in late November were linked to overlapping tropical cyclones hitting Indonesia’s Sumatra region and the Malaysian Peninsula. The disasters killed over 1,800 people and caused economic damage estimated at $25 billion, making this the second-costliest climate disaster of the year and one of the deadliest in recent history.
Other major events included floods in China, India, Pakistan, and Texas, as well as four tropical hurricanes, most notably Hurricane Melissa in the Caribbean, ranked the third-strongest Atlantic hurricane at landfall, causing economic losses exceeding $8 billion. Researchers said rising greenhouse gas concentrations from human activity are driving the increased frequency and intensity of extreme events such as floods, heavy rainfall, storms, and droughts.
The report also noted that the past decade has been the hottest on record, with 2024 identified as the warmest year globally and 2025 ranking second or third. Projections indicate that 2026 is likely to be among the four hottest years in history. Experts warn that without urgent mitigation measures, the economic and human costs of climate-related disasters are expected to rise further in the coming years.
