A drive through the sticky Florida heat into Alton Road in Miami Beach can be an unexpectedly awkward business. Most of the boulevard, which runs north through the heart of the resort’s most opulent palm-fringed real estate, has been reduced to a single lane that is hemmed in by bollards, road-closed signs, diggers, trucks, workmen, stacks of giant concrete cylinders and mounds of grey, foul-smelling earth.
It is an unedifying experience but an illuminating one – for this once glamorous thoroughfare, a few blocks from Miami Beach’s art deco waterfront and its white beaches, has taken on an unexpected role. It now lies on the front line of America’s battle against climate change and the rise in sea levels that it has triggered.
“Climate change is no longer viewed as a future threat round here,” says atmosphere expert Professor Ben Kirtman, of the University of Miami. “It is something that we are having to deal with today.”
