    The World’s Corals Have Passed Their Tipping Point – the Scientist’s Response: “Leave Nature Alone”

    Coral reefs have reached their limit. This is the conclusion of a new global report, which warns that most reefs will likely disappear unless powerful climate measures are taken. But in the midst of this crisis, there are places that show that recovery is possible—if nature is given a chance.

    Coral Reefs Show Resilience Even After the Devastation of the Nuclear Bomb Tests

    Coral Reefs Show Resilience Even After the Devastation of the Nuclear Bomb Tests

    In June 2025, Coral reef researchers, Sylvia Jageroos and Didier Zoccola dived the coral reefs of the Bikini Atoll, observing the coral reef ecosystems, identifying corals and collecting samples. Close on 80 years after American nuclear tests devastated the Atoll, they discovered a surprisingly resilient and healthy ecosystem and will now be able to further analyse their findings to determine whether they have found coral species that are unusually resistant to the effects of climate change. Nästan 80 år efter att amerikanska kärnvapenprov ödelade atollen är det ett överraskande motståndskraftigt och friskt ekosystem de hittar. Tillbaka i labbet ska de analysera fynden för att se om de har hittat korallarter som är ovanligt motståndskraftiga mot klimatförändringarnas effekter.

    Overfishing – Threatening the Climate

    Overfishing – Threatening the Climate

    Overfishing is when we catch more fish than can be born. This leads to a steady decline in populations. Overfishing is a threat to marine fish - but there may be a bigger threat. Listen to scientist Mark Erdmann talk about how climate change and overfishing are linked.

    Efforts underway to save Sweden’s last coral reef

    In the laboratory's aquariums, lush corals glow ghostly white in the dark. But out in the sea, below the surface, there is almost only gravel and dead skeletons left. Here are the scientists who will save Sweden's last coral reef.

    Warmer Seas: Corals are the whistle blowers of the sea

    Warmer Seas: Corals are the whistle blowers of the sea

    The world's coral reefs are in trouble. As the oceans get warmer, corals are stressed and eventually die. Coral scientist Tessa Hempson calls corals the "canary in the coal mine". The little bird that used to be placed far down the mine shafts, because when it died you knew the oxygen in the mine would soon run out. A whistleblower who suffers long before we humans do.
