Ocean temperatures that have gone “crazy haywire” could make the current global coral bleaching the worst in history. It's so bad that scientists are hoping for a few hurricanes as they cool the oceans. More than three-fifths - 62.9% - of the world's coral reefs are badly hurting from a bleaching event that began last year and is continuing. That's nearing the record of 65.7% in 2017, when from 2009 to 2017 about one-seventh of the world's coral died, says Derek Manzello, coordinator of the US's National Oceanic and Atmospheric Administration (NOAA) Coral Reef Watch Program. When water gets to...

Climate change is putting countless marine animals under pressure but jellyfish could actually benefit from warming ocean waters. A study by researchers at Germany’s Alfred Wegener Institute (AWI) looked at eight different species of Arctic jellyfish. They exposed them to rising water temperatures, sea ice retreat and other changing environmental conditions through computer models. Scientists found that by the second half of the century, seven of the eight species could expand their habitat polewards under these conditions. Simulations showed that the lion’s mane jellyfish - one of the biggest...

Scientists studying the sperm whales that live around the Caribbean island of Dominica have described the basic elements of how they might be talking to each other for the first time. They hope the research could one day help better protect them. Like many whales and dolphins, sperm whales are highly social mammals and communicate by squeezing air through their respiratory systems to make strings of rapid clicks that can sound like an extremely loud zipper underwater. The clicks are also used as a form of echolocation to help them track their prey. Scientists have been trying for decades to un...

The number of fish on the US government's overfishing list sunk to a new low last year in a sign of healthy fisheries, federal officials said. The National Oceanic and Atmospheric Administration (NOAA) released an updated analysis of American fisheries late last week via its annual 'Status of the Stocks' report, which provides an assessment of the populations of the seafood species fishermen catch and customers buy. The report states that 94 per cent of fish stocks are not subject to overfishing, which is slightly better than a year ago. The US was able to remove several important fish stocks ...

The Isles of Scilly are 140 islands, 28 miles off the Cornish coast. Five islands are inhabited with a population of just over 2,000 people, the southernmost settled one being St. Agnes. Due to their position at the end of the North Atlantic Drift, they are bathed by the warm waters of the Gulf Stream and can often feel sub-tropical. They don't generally experience the hot and cold temperature swings of the rest of the UK. Instead, with their exquisite blue seas, green landscapes and sparkling white beaches, the Isles of Scilly feel more Mediterranean, although perhaps not as warm as Cornwall....

Europe’s largest reef has welcomed corals bred in a zoo by the World Coral Conservatory project. Gloved divers introduced the corals to the reef at the Royal Burgers’ Zoo in Arnhem on Monday, in the hope that they can one day be used to repopulate natural reefs. “This is the first project where we started to keep these corals with a known origin. As we know exactly where they’re coming from, they have the potential to be placed back into the wild," explains Nienke Klerks, a biologist at the zoo in the Netherlands. "So it is very important to keep these corals, as it’s going not very well in th...

The European Union has voted in favour of ratifying the High Seas Treaty. This treaty aims to protect marine life in areas that are outside of countries’ maritime borders including the high seas and the seabed. The decision is a key step in the process of approving the ratification of the High Seas Treaty. The Parliament’s decision will now be formally adopted by the European Council, after which the EU will be ready to deposit its “instrument of ratification” at the United Nations (UN). It has been classified as a “mixed agreement” by the EU, which means it needs to be ratified at both the EU...

Ten years ago, I stood with then US Secretary of State John Kerry in the spectacular Sant Ocean Hall at the Smithsonian National Museum of Natural History in Washington, DC to discuss an issue that we both hold dear: the state of the world’s oceans. Before that week in 2014, no one had gathered world leaders, funders, non-profits, and academics together under one roof to dedicate time to solving some of the greatest threats facing our oceans. That all changed when Secretary Kerry created Our Ocean – an annual international conference that will meet this week, for the ninth time, in Athens, Gre...

Coral reefs around the world are experiencing global bleaching for the fourth time, top reef scientists declared on Monday, 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 Administration (NOAA) and International Coral Reef Initiative said. It happens when stressed coral expel the algae that are their food source and give them their colour. If the bleaching is severe and long-lasting, the coral can...

The blue economy’s potential to drive global sustainable development will be front and centre this week when the Greek government hosts the ninth Our Ocean Conference here in Athens, against the backdrop of the Mediterranean Sea. Since 2014, leading figures from government, business, civil society, and academia have been gathering at the annual event to take on some of the ocean’s biggest challenges, like climate change, overfishing, pollution, and biodiversity loss. In that time, the international community has mobilized 2,160 commitments worth over $130 billion (€119.7bn) and protected hundr...
