On the first day of the United Nations Ocean Conference in Nice, France, the findings of a new study have revealed that ocean acidification (OA) — which damages ecosystems like coral reefs — is not only getting worse, but crossed its “planetary boundary” roughly five years ago. The findings came as a surprise, as scientists […]
By Hannah Thomasy On its own, a single sea cucumber may not be very impressive. But get enough of these floppy, faceless creatures together, and they—or, more specifically, their poop—can physically and biochemically reshape a coral reef habitat. In a recently published study, an Australian research team used drone surveys, satellite imagery, and observations of […]
As the climate warms, sea levels are rising, tropical storms are intensifying, and ocean waters are growing more acidic. These changes to the oceans have major impacts for people on land, from flooded coastal communities to losses for the fishing industry. So his group is lobbying for what some refer to as a Blue New […]
Sir David Attenborough wants a ban on deep-sea mining. The 93-year-old conservationist spoke out in an interview with Sky News Thursday in conjunction with a new report that warns of the potentially devastating consequences of extracting metals and minerals from the deep places of the ocean. The practice could harm biodiversity, limit the ocean’s ability […]
As the Pacific Ocean becomes more acidic, Dungeness crabs, which live in coastal areas, are seeing their shells eaten away, according to a new study commissioned by the National Oceanic and Atmospheric Administration (NOAA). The study authors looked at ocean acidification levels from 2016. They found that the lowered pH is dissolving the shells of […]
Ocean waters off the coast of California are acidifying twice as fast as the rest of the world’s oceans, new research shows. A study published Monday in the journal Nature Geoscience led by the National Oceanic and Atmospheric Administration used fossil analysis of planktonic organisms to create a 100-year acidification records for California’s ocean waters. […]
By Adrienne Alvord This week Oregon stands on the cusp of approving historic cap-and-invest legislation, HB 2020, that experts have said will help grow the Oregon economy. After three years of legislative consideration, numerous studies, hearings, public meetings and debate, the Oregon House approved the legislation decisively (36-22) on June 18th, and the bill moved […]
As ocean waters warm and acidify, corals across the globe are disappearing. Desperate to prevent the demise of these vital ecosystems, researchers have developed ways to “garden” corals, buying the oceans some much-needed time. University of Miami Rosenstiel School marine biologist Diego Lirman sat down with Josh Chamot of Nexus Media to describe the process […]
By Tim Radford Geoengineering, the deliberate alteration of the planet to undo its inadvertent alteration by humans over the past 200 years, is back on the scientific agenda, with a climate compromise suggested as a possible solution. One group wants to turn down the global thermostat and reverse the global warming trend set in train […]
