10 most costly climate change-related disasters in 2022 revealed

According to a new report, the most expensive climate-related disasters in 2022 were droughts, floods and storms.

Christian Aid’s report found that the 10 most costly events in terms of insured loss ranged from $3bn up to $100bn. However, these figures are just estimates and the actual cost could be higher.

These are the 10 worst disasters of the past year.

459 people died and more than 40,000 were forced to flee their homes over a week. Durban, South Africa’s busiest port, was also shut down.

The report will rekindle debate over who should pay for a “climate catastrophe”. Many of these disasters are occurring in areas that are least responsible for climate change.

This issue was addressed at the COP27 climate talks in Egypt in November. Countries reached a historic pact for a fund to compensate for climate damage.

However, the details about where and who receives the money are still to be determined.

Patrick Watt, chief executive of Christian Aid, said that the numbers in the report show “the financial costs of inaction on climate crisis”.

He said that the human cost of this spiralling crisis is “visible in the homes destroyed by floods, the deaths of loved ones by storms, and the destruction of livelihoods by drought”.
