Bottom Trawling Crackdown: A new study says bottom trawling in EU, UK, Norway and Iceland waters creates up to €16bn a year in net costs to society—about 90 times the fishing industry’s profits—urging bans in Marine Protected Areas to protect marine life and cut climate impacts from disturbed seafloor carbon. Arctic Wildlife Health: Norway’s Svalbard has recorded a polar bear death linked to highly pathogenic bird flu (H5N5), with samples also found in walrus remains, raising alarms for Arctic ecosystems already under pressure. Norway Climate Signals: Norway logged its warmest spring since records began in 1901, with temperatures 2.1°C above normal, and scientists point to fossil-fuel emissions as the driver. Ocean Science: Researchers say ocean temperatures can be reconstructed more reliably using chemistry from tiny foraminifera shells grown in cold conditions, improving past climate readings for Nordic seas. Green Tech & Materials: Vianode and cylib plan to develop next-gen battery anodes using recycled graphite, aiming to cut emissions and strengthen Europe’s supply independence. Shipping Rules: The IMO’s hazardous and noxious cargo liability framework is set to enter into force in 2027, closing a long-standing compensation gap for sea transport accidents.
