Unprecedented ocean heat has triggered the world’s worst mass coral bleaching event on record – a coral massacre so severe, reef experts are looking to one of nature’s most dangerous and destructive forces to provide relief: hurricanes. Since January 2023, 72% of the planet’s reef areas have been bleached by heat stress, surpassing 65.7% during […]

The world’s fourth mass coral bleaching is underway, but well-connected reefs may have a better chance to recover
The world’s coral reefs are like underwater cities, bustling with all kinds of fish and sea animals. Coral reefs cover less than 1% of the ocean, but they support an estimated 25% of all marine species, including many important fish species. The economic value of the services that these complex ecosystems provide is estimated at […]
Experts say coral reef bleaching near record level globally because of ‘crazy’ ocean heat
Ocean temperatures that have gone “crazy haywire” hot, especially in the Atlantic, are close to making the current global coral bleaching event the worst in history. It’s so bad that scientists are hoping for a few hurricanes to cool things off. More than three-fifths — 62.9% — of the world’s coral reefs are badly hurting […]

Climate skeptic dismisses severity of Great Barrier Reef bleaching
Scientists predict recent bleaching at Australia’s Great Barrier Reef will be the worst on record, but skeptics online dismiss the damage by claiming coral populations are at a record high. This is missing context; while there has been growth over the past decade, marine scientists warn global warming has negatively affected biodiversity and resilience in […]
Satellites watch as 4th global coral bleaching event unfolds (image)
Multiple major coral reefs around the world are getting paler due to warming sea temperatures in the fourth-ever global bleaching event, and satellites are keeping tabs on the carnage. The grim event, the second in a decade, is affecting over half the world’s coral area across the Pacific, Indian and Atlantic oceans. The toll includes […]
Coral reef misinformation bubbles up amid bleaching worldwide
Australia’s Great Barrier Reef experienced the most widespread bleaching on record in the summer of 2023 to 2024, with skeptics dismissing the role of human-induced climate change in putting coral barriers under intense heat stress. But scientists say ocean warming is the main cause for repeated, intense bleaching over recent decades. “Coral bleaching is a […]
World’s coral reefs hit by a fourth mass bleaching event, NOAA says
Extreme ocean heat is causing a mass bleaching event in coral reefs across the globe, according to the National Oceanic and Atmospheric Administration. NOAA on Monday declared that a “4th global coral bleaching event” was taking place and that bleaching had been documented over the last 14 months in every major ocean basin, including off […]
Ocean heat is driving a global coral bleaching event, and it could be the worst on record
Coral reefs around the world are experiencing a mass bleaching event as the climate crisis drives record-breaking ocean heat, two scientific bodies announced Monday — with some experts warning this could become the worst bleaching period in recorded history. More than 54% of the world’s coral reef areas have experienced bleaching in the past year, […]
Scientists say coral reefs around the world are experiencing mass bleaching
Coral reefs around the world are experiencing global bleaching for the fourth time, top reef scientists have declared, a result of warming ocean waters amid human-caused climate change. Coral reef bleaching across at least 53 countries, territories or local economies has been confirmed from February 2023 to now, scientists from the National Oceanic and Atmospheric […]
Coral reefs suffer fourth global bleaching event, NOAA says
By Gloria Dickie and Alison Withers (Reuters) – Along coastlines from Australia to Kenya to Mexico, many of the world’s colorful coral reefs have turned a ghostly white in what scientists said on Monday amounted to the fourth global bleaching event in the last three decades. At least 54 countries and territories have experienced mass […]
