Great Escape
Your Climate Change Survival Plan
Unless you’ve booked passage to Mars, it’s time to consider the unimaginable
Three-quarters of the world’s megacities sprawl seaside. More than 40 percent of Americans live in oceanside counties. The National Oceanic and Atmospheric Administration projects that number will increase, even while the seas rise an estimated 20 feet over the next 80 years. Efforts to erect sea walls and implement massive pumping systems are underway in some locales, but even with those measures in place, tens of millions of people will be displaced.
Where will they all go? Most will go inland, of course, and maybe a few will join Elon Musk on Mars. But increasingly, technologists are envisioning off-land human societies—on the water, underwater, and in the air—and they’re developing the technologies that will allow it to happen.
None of this is to downplay the havoc being caused by climate change (or to suggest we should be less diligent about mitigating it), but as legendary sci-fi author Kim Stanley Robinson, whose recent novel New York, 2140 depicts a permanently flooded but still-vibrant Manhattan, says, “It’s important to stay positive about the future, no matter how messed up things are now.”
