Climate change is already making floods more frequent and more destructive. As the world warms, the atmosphere can hold more water vapor. That extra moisture is available to fall as rain or snow, which can lead to more extreme precipitation events.
Climate change is also causing sea level rise. When combined with the increased frequency of extreme precipitation events, this means that more areas are at risk of flooding.
Flooding can have a significant impact on people and the environment. It can damage homes and infrastructure, and lead to loss of life. Flooding can also contaminate water supplies and damage crops.
Restoring an area after a flood can be a costly and difficult process. It is important to take steps to reduce the risk of flooding, such as by planting trees and constructing barriers.
