Sea levels are rising. But the San Francisco Bay Area has another problem: It’s sinking. By 2100, it could lose 165 square miles to the sea.

The developing world is nowhere near ready to deal with subsidence and rising seas, but neither is the developed world. This is a problem that defies human ingenuity. It’s not like the San Francisco Bay Area can build one giant sea wall to insulate itself. And it’s not like low-lying Florida can hike itself up, or New York City can move itself inland a few hundred miles.

“There is no permanent solution to this problem,” says Arizona State University geophysicist Manoochehr Shirzaei, lead author of the paper. “This will impact us one way or another. The forces are immense, it’s a very powerful process, the cost of really dealing with it is huge, and it requires long-term planning. I’m not so sure there’s a good way to avoid it.”
