Have you ever considered how much future coastal flooding could impact our world?

Global warming can be difficult to visualize. If you’re not directly impacted by rising sea levels and future coastal flooding, water shortages, or wildfire ravages, how do you know it’s really happening? It can all seem a little abstract, right?

Well, the truth is that rising ocean waters will completely inundate many coastal land areas by the end of the century, according to data produced by Climate Central, to project annual flood levels better.

With sea levels rising worldwide, several major metropolises are at risk of submerging. But a lot can change between now and then. We could build flood defenses, adapt our cities, and, ideally, our governments could finally take serious action to stop the climate crisis.

But if none of that happens, here are just 28 of the incredible places worldwide that could be underwater in a number of decades if significant steps to prepare for future coastal flooding aren’t taken.

…Hint: Many of the future coastal flooding sites on our list are in the US!
