HOBOKEN, N.J. (AP) — Superstorm Sandy and a series of lesser coastal storms since that 2012 disaster compelled some coastal communities to defend themselves by elevating homes and critical infrastructure, building sand dunes, widening beaches and erecting or raising sea walls.
But as sea levels continue to rise around the world, that’s not an option in large cities, where skyscrapers can’t be elevated and subway and train tunnels act as turbocharged flumes when millions of gallons of stormwater rush through them.
