The extent of coral reefs worldwide has played a key role in Earth’s climate in the past 250 million years – but not in the way you might expect. Coral reefs are net producers of carbon dioxide ...

Scientists have found that the 2023 marine heat wave caused “functional extinction” of two Acropora reef-building coral species living in the Florida Reef, which stretches from the Dry Tortugas ...

In early June 2023, the coral reefs in the lower Florida Keys and the Dry Tortugas were stunning. We were in diving gear, checking up on hundreds of corals we had transplanted as part of our ...

Elkhorn and staghorn corals used to carpet Florida’s reef system, rising like antlers from the seabed — but not anymore. These crucial coral species are now “functionally extinct” in the region after ...

A recent surge in ocean temperatures has caused the widespread bleaching and death of warm-water corals around the world, officially triggering the first climate tipping point for one of Earth’s ...

Coral reefs around the globe have for years suffered publicly in warming oceans, periodically making headlines when iconic underwater landscapes lose their colors and wither during repeated mass ...

Coral bleaching isn’t just an ocean crisis. Here’s how the global event endangers food security, local jobs—and the land itself. Sea water divides the sunset and a ghost land of corals in New Ireland, ...

Global temperature rise may feel like it’s gradual, but the changes it brings can turn out to be sudden, massive, and self-reinforcing. These changes are what scientists call tipping points. When a ...

The Coral Triangle is an extremely biodiverse patch of ocean around the Philippines and Papua New Guinea. Its relatively murky waters appear to shield it against climate change — for now. When you ...
