This Is What Your City Would Look Like If All the World's Ice Sheets Melt
You're going to need to learn the names of some new islands.
Each map includes newly named islands and bays, like the "Chula del Mar" in San Diego. In L.A., the city of Downey has become "Drowney," and the airport is "Ex-LAX." The map also notates where landmarks like Disneyland and the Miracle Mile would end up in the newly formed bay.
The mapmaker was inspired by a similar map by a San Francisco blogger. "I'd always been fascinated by what the world would look like with a sea level rise," Linn says. "I was very impressed with his take on it. So I stole his concept."
The maps show a very long-term vision of the future but point to what's happening today. "These maps are an extreme scenario, and it would probably happen thousands of years in the future," Linn says. "I think that the real damage comes long before this extreme final point."
By 2100, the Intergovernmental Panel on Climate Change predicts a sea level rise between 1.7 and 3.2 feet; other climate scientists say it might be as much as 4 feet, and nearly 10 feet by 2300. And while that's not enough to drown Portland, it's sufficient to devastate coastal cities.
So far, Linn has created maps for six cities, and is interested in going farther. "I've been thinking it would be really cool to do an atlas of cities worldwide," he says.
