A new JRC report looks at flood risk and economic damages under different global warming scenarios with 1.5˚C, 2˚C, and 4˚C temperature increases. It concludes that, if global temperatures rise by 4°C, the flood risk in countries representing more than 70% of the global population and of the global GDP will increase by more than 500%.

The study reveals that, with a 4°C temperature increase globally, countries representing 73% of the global population would face a 580% increase in flood risk. In addition, 79% of the global economy would face a 500% increase in flood damages. In the case of a 2°C temperature increase, both the affected population and the related flood damages would rise by 170% compared to present levels. Even under the most optimistic scenario of a 1.5°C temperature increase, the authors estimate that the flood-affected population would still double, and flood damages would increase by 120%.
The projected changes are not evenly distributed across the globe. The increase in flood risk is highest for Asia, America and Europe, while it remains low for most countries in Africa and Oceania, independent of the temperature increase.
