As Director of Florida Keys Sanctuaries, Causey Sees Changes to Corals ‘In Our Lifetime’

KEY WEST, FLA. – Since the 1970s, Billy Causey has observed ominous signs of change in the coral reefs of the Florida Keys. As southeast regional director for the National Marine Sanctuary Program of the National Oceanic and Atmospheric Administration, Causey has a front-row seat.

He has spent decades diving on Florida’s coast, where he has witnessed effects of warming waters and ocean acidification on reef ecosystems. (Click below to see a three-minute video interview with Causey.)

“I think in our lifetime, we’re going to have to be prepared to see corals change,” Causey said. “The fact that corals are telling us ‘Change is coming’ is something we need to be paying attention to.”

At his seaside office in Key West, Sara Peach talked with Causey about how corals are changing … and why most tourists do not notice the difference.
