The expected arrival of El Niño this summer could trigger another mass coral bleaching event, which would be the fifth on record, researchers said.
According to a recent report, the world has reached its first climate change tipping point. Scientists point to the widespread bleaching of coral reefs due to rising ocean temperatures. Cristian Benavides reports on the Reefline, a manmade art installation and restoration project.
A record 2023 heat wave all but eradicated two species of coral that historically served as the backbone of Florida's reefs, researchers said in a new report.
For years, scientists and the U.N. have spoken about critical climate tipping points that, if crossed, could potentially cause irreversible changes to the planet and accelerate climate change. According to a report published Monday by researchers at the University of Exeter, the first tipping point has likely already been reached for coral reefs. CBS News senior coordinating producer for climate and environmental coverage Tracy Wholf explains.
Crucial for marine life and the global economy, coral reefs are the planet's first major environmental system to cross a climate "tipping point" as the world warms.
About 200 coral pieces were plucked from the water somewhere in Indonesia, packaged up, and sent by plane to the U.S., where they were discovered and seized by the U.S. Fish and Wildlife Service.
Hundreds of live corals were illegally smuggled halfway around the world, but instead of certain death, Bradley Blackburn reports on the effort to nurse them back to life.
Elkhorn coral helps form the skeleton of a healthy reef, but more than 95% of the Elkhorn coral off Florida has been wiped out. Scientists have created the "Flonduran" crossbreed to solve the problem.
The warming ocean waters off the Florida coast have had a devastating impact on Florida's coral reef. Manuel Bojorquez reports on how scientists now believe they have found at least one way to give the coral a fighting chance.
Coral reefs in Honolulu and other coastal areas are undergoing what experts say is the world's worst coral bleaching event.
Beneath the world's oceans, a seismic event is occurring. Coral reefs, essential for maintaining marine life and coastal storm protection, are slowly dying in the climate change-fueled warming waters. Karen Hua reports.
Harmful bleaching of the world's coral has grown to include 84% of the ocean's reefs in the most intense event of its kind in recorded history, scientists say.
Scientists say they've discovered a "mega coral" three times bigger than the previous record holder - so huge they initially thought it was a shipwreck.
New data from the National Oceanic and Atmospheric Administration has scientists ringing alarm bells about the health of the world's oceans. Seventy-seven percent of the world's coral reefs have experienced "bleaching-level heat stress" over the last 22 months. Derek Manzello, coordinator of NOAA's Coral Reef Watch program, joins CBS News to dive deeper into the research.
Scientists have moved about 300 endangered sea corals from South Florida to the Texas Gulf Coast for research and restoration.
According to NOAA, last month was the hottest June on record globally, and sea temperatures stayed well above average. The hotter-than-usual ocean water is a cause for concern for delicate coral reefs. In Florida, a group of veterans is working to help restore the vital ecosystems — and it's helping more than just the reefs.
A global shark census found in 2018 that the population of five main reef shark species, which are key to balancing the ecosystem of coral reefs, had declined 63%. Ben Tracy takes a look at a group working to protect these necessary predators.
More than 100 nations, including the United States, have agreed to protect 30% of the world's oceans by 2030.
The mass bleaching event comes as the world saw record-high sea surface temperatures and the hottest February ever recorded.
The revised coral bleaching alert levels come in the wake of Florida experiencing hot tub-level sea temperatures and some reefs experiencing "100% mortality."
The 6.4 million-acre reef is bigger than the state of Vermont, NOAA says.
The U.S. Navy says underwater footage shows two points where a large surveillance plane is touching coral in the Hawaii bay where it landed more than a week ago.
New underwater video was released of a Navy spy plane which overshot a runway in Hawaii and landed in a bay. The video shows the tires of the plane sitting on an ecologically-sensitive reef. The Navy is trying to consider how to safely remove the plane.
The coral reefs off the shores of the Florida Keys should be vibrant and colorful this time of year. But scientists say they're seeing a very different picture. CBS News' Manuel Bojorquez reports on a race to save the coral – by removing them from their habitat.
