The National Climate Risk Assessment reveals that by 2050, 1.5 million coastal residents in Australia could lose their homes due to rising sea levels. The 2019-2020 bushfires killed nearly one billion animals, while the Great Barrier Reef’s coral cover had dropped to 38% by 2025, with fisheries projected to lose A$1.2 billion. Despite pledging a…

The State of the World’s Coastal Ecosystems Report was released at the Global Coastal Forum in Yancheng. The report indicates that over the past 50 years, typical ecosystems such as seagrass beds, coral reefs, and mollusk reefs have experienced an average annual net loss exceeding 1%, with tropical regions being particularly affected. 97% of mangroves…

A September 25 study in Communications Earth & Environment reveals that while WWII munitions on the Baltic Sea floor release toxic substances like TNT, their hard surfaces attract five times more marine life—such as tube worms and shellfish—than sedimentary areas. The study suggests this paradoxical “coexistence of pollution and habitat” may occur because the munitions’…

Scientists at Florida Atlantic University’s Harbor Branch Oceanographic Institute recently released a comprehensive review on Atlantic drifting brown algae. The study reveals that this free-floating brown seaweed is spreading across the Atlantic at an alarming rate, driven by both natural variations and nutrient inputs triggered by human activities. Nutrient inputs from human activities intensify impacts…

In September local time, Chuuk State in the Federated States of Micronesia declared a state of emergency due to a fuel leak from a World War II-era shipwreck. Local divers discovered the Japanese vessel Rio de Janeiro Maru leaking fuel, with the oil slick spreading over approximately 3.4 miles of coastline. The spill has affected…

Recently, Indonesia’s Ministry of Marine Affairs and Fisheries launched the “Healthy Waste-Free Ocean” initiative and national mangrove conservation zone development to comprehensively advance integrated marine ecological management. The plan aims to implement coordinated land-sea governance measures for end-to-end control of marine debris, striving to reduce waste discharged into the ocean by 40% by 2026 and…

A recent study by the Scripps Institution of Oceanography at the University of California, San Diego reveals that old barrels left on the seabed near the Los Angeles coast from the 1930s to the 1970s continue to leak toxic substances into the ocean. In addition to containing DDT, these barrels may also hold corrosive alkaline…

On September 8, the Philippine Coast Guard announced that nine new valve leak points were discovered on the “Terranova” oil tanker (carrying 1.4 million liters of industrial fuel), which sank in Manila Bay in July 2024. The leaked fuel has formed a 3.7-kilometer-long oil slick, spreading with monsoon winds and ocean currents into ecologically sensitive…

In September local time, approximately 3 tons of ultra-low sulfur fuel leaked into the sea from the Liberian-flagged cargo ship MSC Elsa 3 during refueling operations at Puerto de Las Palmas, Gran Canaria. The oil slick rapidly spread across a 2-kilometer-long and 400-meter-wide area, prompting local authorities to close multiple beaches and issue a red…

Mexico’s Yucatán Peninsula coastline has suffered an unprecedented invasion of Sargassum algae, with 4,236 tons of seaweed cleared from just seven ports in Quintana Roo state. This massive accumulation of floating brown algae not only releases toxic gases like hydrogen sulfide but also causes a 73% drop in seawater oxygen levels and a 5°C temperature…
