SNIP: U.S. government scientists have found a dramatic impact from the continuing decline of coral reefs: The seafloor around them is eroding and sinking, deepening coastal waters and exposing nearby communities to damaging waves that reefs used to weaken.

“We knew that coral reefs were degrading, but we didn’t really know how much until we did this study,” said USGS oceanographer Kimberly Yates, the lead study author. “We didn’t really realize until now that they’re degrading enough that it’s actually affecting the rest of the seafloor as well.”

Erosion of coral reefs and seafloor is happening much more and much faster than what was previously known or expected, enough so that it’s affecting those local sea level rises,” said Yates. “Enough so that it increases the risk to the coastlines from coastal hazards, storm waves, every day persistent waves, tsunamis and those kinds of things.”
