Nov 21 (Reuters) – Climate change has raised the cost of natural disasters, as rising sea levels and drought increase the frequency and severity of flooding and wildfires, insurers and risk modelling experts say.
The list of the 10 most expensive events of the last decade provided to Reuters by risk modelling firm RMS all took place over the last five years.
While the biggest losses are usually in richer countries with more expensive assets, developing countries such as Pakistan, which suffered flooding this year that cost an estimated $40 billion, often bear the brunt of damaging weather.
How to get money to poorer countries after climate disasters was a dominant theme at the COP27 climate talks in Egypt, and insurance is seen as one way to do that.
A G7-led plan dubbed “Global Shield” to provide pre-arranged insurance and disaster protection funding to countries suffering climate disasters was also launched at the climate conference.
The disasters are ranked by economic losses, both insured and uninsured, with the costliest first.

Total loss: 40 billion euros ($40.93 billion)
7. Pakistan floods June-Aug 2022
Intense monsoon rains and unusual heat in the Karakoram Mountains led to unprecedented glacial melt, starting floods on June 14. Floodwaters in flat-lying Indus floodplains took months to recede. The floods displaced eight million people.
Total loss: $40 billion (revised up from early estimates of $3 billion)
8. Typhoons Faxai and Hagibis in Japan Aug-Oct 2019

10. Northwestern U.S. and British Columbia Canada heatwave June-July 2021
An extreme heatwave from June 25 to July 1 across western Canada and the U.S. Pacific Northwest, caused many wildfires.
Total loss: $8.9 billion
Fatalities: 1,400 as a result of excess heat
