In 100 years, what will a United States transformed by climate change look like? At this point, you don’t have to use much imagination to predict what’s coming: Temperatures will continue to climb; sea levels will continue to rise. And, by the 2060s, the U.S. Census Bureau estimates that global migration patterns will bring 100 million new people into the country, who will settle from coast to coast.
Almost everything else about the climate of tomorrow and the nation’s ability to survive it is less inevitable, however, says Billy Fleming, the director of the University of Pennsylvania’s McHarg Center for Urbanism and Ecology. “There are certain general things we’re certain about, but the shape and content of the future is not one of them,” he said. “We get the future we build for ourselves.”
