Extreme precipitation and storms driven by interactions between and disturbances within oceanic and atmospheric systems can lead to large-scale flooding. In the future, climate change may have major implications for these processes. According to the Intergovernmental Panel on Climate Change’s (IPCC) sixth assessment report (AR6), increased rainfall may lead to increased flooding in many parts of the world. Similarly, coastal regions may face wetter, windier, and more intense tropical storms in a warming world. Rising sea levels, together with an increase in episodes of extreme precipitation and greater frequency and magnitude of storm surges, will aggravate coastal inundation, while an increase in episodes of extreme precipitation will aggravate flood problems in low-lying river basins and urban areas. In a warmer world, to decrease the threat of increased flooding from extreme rainfall and storm hazards, a new paradigm consisting of the creation and management of coastal mangroves, afforestation of uplands and coastal areas, conservation, restoration, creation of wetlands and rivers connected to flood plains as buffers is needed. These approaches must be pursued together with the use of advanced community-friendly flood forecasting and warning arrangements and the strengthening of the institutions responsible for such arrangements and for reducing disaster risks. Encouraging people to shift to safer areas and enhancing the emergency response capabilities of state agencies are additional measures that must be adopted.
