The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on …
US researchers have found that blowing tiny bubbles through sea water could help protect coral reefs and oyster farms from oceans, which have increasingly turned acidic through human activities. The idea is that tiny bubbles will help cleanse the world's oceans of carbon dioxide (CO2) by drawing the gas out …
Order of the United States District Court in the matter of Budha Ismail Jam & Others Vs International Finance Corporation dated 24/03/2016 regarding environmental and social harm caused by the coal-fired Tata Mundra Power Plant to the marine ecosystem, to the quality of the air, to plaintiffs’ (fishermen and farmers) …
Australian scientists managing the Great Barrier Reef have lifted their emergency response to the highest level following the publication of video footage of damage caused by coral bleaching. Authorities this month said that areas of the World Heritage site were experiencing the worst bleaching in 15 years, at least partially …
A manipulative experiment in which a reef is alkalinized in situ shows that calcification rates are likely to be lower already than they were in pre-industrial times because of acidification.
Damage to parts of the Great Barrier Reef has worsened, leading authorities to raise the alert to the second-highest level, indicating severe local coral bleaching. The bleaching is worst in the most pristine and remote parts of the reef north of Cairns, according to Terry Hughes, convenor of the National …
Ocean ecosystems play a critical role in the Earth's carbon cycle and the quantification of their impacts for both present conditions and for predictions into the future remains one of the greatest challenges in oceanography. The goal of the EXport Processes in the Ocean from Remote Sensing (EXPORTS) Science Plan …
Sandy beaches are being threatened by a changing climate. However, the effects of this changing environment, including warming, on these ecosystems, have hitherto been tentative and qualitative. Using concurrent long-term (1984−2007) observations on abundance and individual size, together with laboratory examinations of body abnormalities (morphological anomalies and epibionts), we provide …
The Supreme Court has declined to hear a challenge to the Chesapeake Bay cleanup plan, the largest attempt by the federal government and states to rid the pollution from a body of water and to restore its health. The high court’s refusal ends an attempt by the American Farm Bureau …
Indore: In a rare discovery, palaeontologists have stumbled upon a nine crore-year-old rare coral fossil similar to that of brain coral in Bagh beds of Narmada valley region. This suggests the presence of marine life and sea in Central India during evolution. Discovery of coral fossil is also likely to …
The problem of marine pollution by plastics can be resolved through a combination of actions like enforcement of rules, stressing on recycling and finding an alternative to plastics, say experts. "Resolving the plastic debris problem is important. Solutions to the plastic debris can only be achieved through combination of actions," …
The Arctic is thawing even faster than lawmakers can formulate new rules to prevent the environmental threat of heavy fuel oil pollution from ships plying an increasingly popular trade route. Average Arctic temperatures are rising twice as fast as elsewhere in the world and the polar ice cap's permanent cover …
The third global coral bleaching event to be recorded is snaking its way around a warming globe, devastating reefs and now threatening the world-heritage listed Great Barrier Reef. This week it was announced the bleaching event, which began in 2014, is already the longest in history and could extend well …
Thousands of shipwrecks spanning more than 500 years of marine history are being used to better understand the health of deep-ocean eco-systems. An international team of scientists initially set out to investigate the effects of the 2010 Deepwater Horizon oil spill in the Gulf of Mexico, which saw more than …
The Great Barrier Reef (GBR) is founded on reef-building corals. Corals build their exoskeleton with aragonite, but ocean acidification is lowering the aragonite saturation state of seawater (Ωa). The downscaling of ocean acidification projections from global to GBR scales requires the set of regional drivers controlling Ωa to be resolved. …
Europe's ecosystems face increasing pressure to stay healthy amid rising pollution, exploitation, urban sprawl, and the effects of climate change, according to the findings of a European Environment Agency (EEA) report published on Monday. The EEA report looks at eight broad ecosystem types in Europe and assesses the pressures and …
Europe’s ecosystems face increasing pressure to stay healthy amid rising pollution, overexploitation, urban sprawl and the effects of climate change. These are the findings of a European Environment Agency (EEA) report published which takes stock of the condition of Europe’s ecosystems. The EEA report ‘Mapping and assessing the condition of …
The end-Permian mass extinction not only decimated taxonomic diversity but also disrupted the functioning of global ecosystems and the stability of biogeochemical cycles. Explaining the 5-million-year delay between the mass extinction and Earth system recovery remains a fundamental challenge in both the Earth and biological sciences. We use coupled records …
Governments take the advice they want to hear. As they seek to avoid trouble and find the path of least resistance, they often look for advice that meshes with the demands of industrial lobbyists. This problem has afflicted the life of the sea for many years. Governments consult the scientists …
Pretoria — Environmental Affairs Minister Edna Molewa has published draft notices and regulations in the Government Gazette to declare a network of 22 new proposed Marine Protected Areas (MPAs) as part of Operation Phakisa. "The declaration of these new MPAs aims to create approximately 70 000km² of marine protected areas, …
Carbon dioxide removal (CDR) approaches are efforts to reduce the atmospheric CO2 concentration. Here we use a marine carbon cycle model to investigate the effects of one CDR technique: the open ocean dissolution of the iron-containing mineral olivine. We analyse the maximum CDR potential of an annual dissolution of 3 …
