2023 hottest year on record as Earth nears critical 1.5C limit: monitor

By Rochelle GLUZMAN PARIS, Jan 9, 2024 (AFP) – The year of 2023 was the hottest on record, with the increase in Earth’s surface temperature nearly crossing the critical threshold of 1.5 degrees Celsius, EU climate monitors said Tuesday. Climate change intensified heatwaves, droughts and wildfires across the planet, and pushed the global thermometer 1.48 C above the preindustrial benchmark, the Copernicus Climate Change Service (C3S) reported. “It is also the first year with all […]

Conservation meet mulls moratorium on deep sea mining

by Laure FILLON Agence France-Presse MARSEILLE, France (AFP) – The world’s top conservation forum will vote this week on whether to recommend a moratorium on deep sea mining, with scientists warning that ecosystems degraded while dredging the ocean floor 5,000 metres below the waves could take decades or longer to heal. The proposed ban is among a score of measures deemed too controversial to be decided remotely ahead of the International Union for the Conservation […]

Ocean surface climates may disappear by 2100: study

by Patrick GALEY PARIS, France (AFP) — Up to 95 percent of Earth’s ocean surface will have changed by the end of the century unless humanity reins in its carbon emissions, according to research published Thursday. Ocean surface climates, defined by surface water temperature, acidity and the concentration of the mineral aragonite — which many marine animals use to form bones and shell — support the vast majority of sea life. The world’s seas have […]

New Chinese submersible reaches Earth’s deepest ocean trench

BEIJING, China (AFP) — China livestreamed footage of its new manned submersible parked at the bottom of the ocean Friday, the latest foray by the country’s scientists into the Earth’s deepest ocean trench. The vessel “Fendouzhe”, or “Striver”, descended more than 10,000 metres into the Pacific Ocean’s Mariana Trench with three researchers on board, state broadcaster CCTV said. Video footage shot and relayed by a deep-sea camera showed the green-and-white submersible moving through dark water […]

Atlantic plastic levels far higher than thought: study

by Patrick GALEY PARIS, France (AFP) — There may be more plastic floating just beneath the surface of the Atlantic ocean today than the estimated total weight of plastic waste dumped in it since 1950, new research showed Tuesday. The findings, based on analysis of samples of the three most common plastic materials and computer modelling, highlight the unseen scale of the pollution clogging the world’s second-largest ocean. Earth’s oceans contain an estimated 150 million […]

Marine heatwaves may force fish to flee huge distances: study

by Kelly MACNAMARA PARIS, France (AFP) — Fish and other marine life may have to flee thousands of kilometres to escape damaging heatwaves, according to research published Wednesday, highlighting the scale of disruption caused by these increasing surges in ocean temperatures. Hot spells can cause dramatic changes to ocean ecosystems, devastating coral habitats, killing large numbers of seabirds and forcing species like fish, whales and turtles into colder waters. Researchers said the increasing number of […]

Reef tales: candid cams reveal shark populations in decline

by Sara HUSSEIN TOKYO, Japan (APF) — An unprecedented global survey has revealed a shocking decline in the number of reef sharks, with the predators “functionally extinct” on nearly 20 percent of sites studied. The four-year study used more than 15,000 baited and remotely operated cameras — so-called “chum cams” — to obtain the first comprehensive picture of where reef sharks are thriving and where they are virtually non-existent. The results, from over 370 reefs […]

Aussie scientists turn to drones to protect sea turtles

BRISBANE, Australia (AFP) — Australian researchers have discovered they were underestimating numbers at the world’s largest sea turtle nesting site after turning to drone technology for the first time. Raine Island, off the northern tip of Australia, plays host to around 60,000 female green turtles who migrate hundreds of kilometers from the Great Barrier Reef to lay their eggs each year. Scientists working to protect the endangered species had struggled with how best to keep […]

Half of world’s beaches could vanish by 2100

by Marlowe HOOD PARIS, France (AFP) — Climate change and sea-level rise are currently on track to wipe out half the world’s sandy beaches by 2100, researchers warned Monday. Even if humanity sharply reduces the fossil fuel pollution that drives global warming, more than a third of the planet’s sandy shorelines could disappear by then, crippling coastal tourism in countries large and small, they reported in the journal Nature Climate Change. “Apart from tourism, sandy […]

Researchers to conduct major Japan ocean microplastics survey

TOKYO, Japan (AFP) – Scientists will begin a two-year survey of microplastics in the coastal waters of Japan from April, a research group announced on Wednesday, with concern growing about the impact of plastics on the oceans. The survey organized by Japanese scientists and the Tara Ocean Foundation will be conducted by several marine research facilities located across Japan, from the northern island of Hokkaido to southwestern Kyushu. Researchers will collect samples for analysis of microplastics […]

Adidas bets on recycled material ‘to combat ocean plastic’

FRANKFURT AM MAIN, Germany (AFP) – German sportswear giant Adidas said Tuesday more than half of the polyester used in its products this year would come from recycled material, including millions of shoes made from plastic waste. In 2020, the share of recycled polyester in Adidas products will “exceed 50 percent for the first time”, the company said in a statement. By 2024, Adidas “is committed to using only recycled polyester” across its entire range of […]

Oceans were hottest on record in 2019

by Patrick GALEY PARIS, France (AFP) — The world’s oceans were the hottest in recorded history in 2019, scientists said on Tuesday, as manmade emissions warmed seas at an ever-increasing rate with potentially disastrous impacts on Earth’s climate. Oceans absorb more than 90 percent of excess heat created by greenhouse gas emissions and quantifying how much they have warmed up in recent years gives scientists an accurate read on the rate of global warming. A […]
