Warm seawater kills most of the coral grown in the Florida Keys

Record sea water temperatures killed more than three-quarters of the man-grown coral that scientists had placed in the florida keys in recent years in an attempt to keep a threatened species highly vulnerable to climate change, researchers discovered.

Researchers of the National Office of Oceanic and Atmospheric Administration (NOAA) They returned this week to five reefs where they had planted staghorn and elkhorn coral, both listed as threatened on the endangered species list, to see how they had responded to continued high water temperatures. above 90 degrees Fahrenheitduring last summer and fall. Most did not survive.

Besides, observed widespread deaths in both stocked and wild corals on five reefs in the Keys.

Scientists blame man-made climate change, with the push of the natural phenomenon El Niño, to make the water too warm for the delicate corals, which are animals, to survive. After trying to rescue corals last hot summer, This was the scientists' first winter dive to check what had survived.
