What will be flooded by 2050?
The Bahamas. Many small island nations will be catastrophically affected by sea-level rises in the future, including The Bahamas, which was devastated by Hurricane Dorian in 2019. Most of Grand Bahama, including Nassau (pictured), Abaco and Spanish Wells are projected to be underwater by 2050 because of climate change.
How much will sea levels rise in the next 100 years?
But if seas rise 20 feet or more over the next 100 to 200 years — which is our current trajectory – the outlook is grim. In that scenario, there could be two feet of sea level rise by 2040, three feet by 2050, and much more to come.
How does the global flood risk map work?
Click on individual points for current elevation, elevation after sea level rise, and the number and percentage of people losing homes. Global Flood Map uses NASA satellite data to show the areas of the world under water and at risk for flooding if ocean levels rise.
How to find out if there is a flood in your area?
Click on a state to learn more about the types of flooding experienced there and how residents can protect their lives and property. You will also find information on the top 5 floods for each state, learn which National Weather Service offices forecast for the area and more!
How are low lying areas affected by flooding?
Low-lying areas, displayed in green, are hydrologically “unconnected” areas that may also flood. They are determined solely by how well the elevation data captures the area’s drainage characteristics. The mapping may not accurately capture detailed hydrologic/hydraulic features such as canals, ditches, and stormwater infrastructure.
What does negative elevation mean on a flood map?
We also think that it can help in planning irrigation system and water management. By setting negative elevation, Bathymetry study is also possible. The elevation layered on the map is in meters and is from sea level. The elevation is zero for the sea level. Negative elevation means depth below sea level.
