Storm Ida causes $ 65 billion in losses

This economic ranking overrepresents the disasters that have occurred in rich countries, with more developed and better insured infrastructure, but the NGO recalls that some of the most devastating extreme weather events of 2021 have hit poor countries, which have contributed little to the causes of change. climatic and where most damage is not insured. In South Sudan, floods, the economic cost of which could not be estimated, affected some 800,000 people.
