This should honestly alarm people, IMO:

The coral reef off southeast Florida is experiencing an unprecedented and potentially deadly level of bleaching this summer because of rising ocean temperatures caused by climate change, federal scientists said Thursday.

Some sites around the Florida Keys are being exposed to twice the amount of heat stress that causes corals to die, and earlier in the year than ever before, scientists from the National Oceanic and Atmospheric Administration said in a telephone news conference. They said the phenomenon is likely to affect the Caribbean very soon and a global bleaching event could be just around the corner.

“We are quite concerned and worried and stressed about this event,” said Ian Enochs, a research ecologist at NOAA’s Atlantic Oceanographic & Meteorological Laboratory. “It’s not a normal thing.”

It's definitely not good that things like this are happening.
