Nepal-Tibet floods add to the world's growing natural disaster economic bill

The recent Nepal-Tibet floods have highlighted the escalating issue of natural disasters in the context of climate change. Such catastrophes are becoming increasingly deadly and costly, with uncertainty surrounding their future impact. The Organisation for Economic Co-operation and Development stated that climate change affects all aspects of life and natural environments, posing significant risks to livelihoods, socio-economic stability, and the environment.

In 2023 alone, there were 48 recorded natural disasters, including floods, earthquakes, wildfires, typhoons, and windstorms, according to ReliefWeb data. The economic damage caused by these disasters is substantial, with estimates ranging from $120 billion to $2 trillion globally over the past decade.

Last year, the Palisades and Eaton wildfires in Los Angeles resulted in economic losses exceeding $60 billion, while tropical cyclones that hit Southeast Asia cost about $25 billion. Climate change intensified these cyclones, making them more powerful than they would have been without human-induced warming.

Historically, some of the costliest natural disasters include the 2011 Tohoku earthquake and tsunami in Japan, which caused over $320 billion in damage, and Hurricane Katrina in 2005, which is estimated to have cost over $200 billion. In 2022 and 2023, extreme weather events caused $451 billion in damages, almost doubling the losses of the previous eight years combined.

The European Environment Agency reported that weather and climate-related extremes have cost the EU about €822 billion ($952.2 billion) from 1980 to 2024, with more than €208 billion occurring between 2021 and 2024. Despite the severity of these losses, precisely quantifying the economic impact of climate change remains challenging due to the complexity and variability of the factors involved.
