warning of major impacts


A sudden marine heat wave off the coast of Florida has surprised scientists and sent water temperatures soaring to unprecedented highs, threatening one of the most severe coral bleaching events the state has ever seen.

Sea surface temperatures around Florida have reached the highest levels on record since satellites began collecting ocean data. And the warming is happening much earlier than normal – yet another example of ocean heat being amplified by the human-caused climate crisis and the extreme weather it brings

.“We didn’t expect this heating to happen so early in the year and to be so extreme,” Derek Manzello, a coordinator at the National Oceanic and Atmospheric Administration’s Coral Reef Watch, said.

“This appears to be unprecedented in our records.”The exceptional temperatures – close to 97 degrees Fahrenheit in some areas – are more than just another alarming climate record; extreme ocean heat and its duration are critical in deciding the survival of coral reefs.

Temperatures that are too hot for too long cause coral to bleach, turning a ghastly white as they expel their algal food source and slowly starve to death.
