In September 2015, 193 world leaders agreed to 17 Global Goals for Sustainable Development. If these Goals are completed, it would mean an end to extreme poverty, inequality and climate change by 2030.
Goal 14: Conserve and sustainably use the oceans, seas and marine resources for sustainable development.

• [New] Russian electronic warfare systems are systematically disrupting satellite navigation in the Baltic Sea, creating risks for shipping and aviation. RBC-Ukraine
• [New] This month, the Australian government quadrupled the size of its Heard Island and McDonald Islands Marine Reserve, a move that will help protect Antarctic marine life. Conservation International
• [New] At current rates, just under 10% of the world's oceans will be protected by 2030 - a far cry from what scientists say is needed to stop the loss of marine biodiversity, stem the climate crisis, and protect communities that rely on oceans for food and livelihoods. Conservation International
• [New] The naval end-user segment is expected to exhibit a noteworthy CAGR of 9.6% from 2026 to 2034 due to heightened maritime tensions in the Baltic, Black Sea, and North Atlantic, where surface vessels face sophisticated anti-ship missile threats and electronic surveillance. Market Data Forecast
• [New] Marine pollution is a threat to the livelihoods of more than 3 billion people all over the world. Greenpeace Africa
• [New] A likely El Nino return in late 2026, layered on record-warm oceans, is raising concerns over flight disruption, coastal tourism risks, and fragile travel hotspots. The Traveler
• [New] The Royal Netherlands Navy's fleet-wide integration of 12 AI-enabled V-BAT systems across eight warships suggests a deliberate NATO-aligned shift toward autonomous maritime ISR that could complicate adversary surface and subsurface operations in the North Sea and Norwegian Sea corridors. Drone Warfare
• [New] 2026's seasonal Sargassum blooms will grow to record-breaking proportions as they drift across the Atlantic Ocean. Popular Science
• [New] The melting of the Arctic's glaciers and ice sheets can contribute to rising sea levels, putting coastal communities around the globe at risk. GSAP News
• [New] Cities such as Miami, New York, Jakarta, Shanghai, Mumbai, and Lagos are frequently highlighted in sea level rise projections as being at higher risk of coastal flooding. Nature World News
• [New] By 2050, several major coastal cities are expected to face sharper exposure to both chronic sea level rise and acute coastal flooding. Nature World News
• [New] NOAA has outlined how U.S. coasts are likely to see up to about a foot of sea level rise by 2050, which would already increase the reach and depth of coastal flooding during storms and high tides. Nature World News
• [New] Under moderate emissions, the world's oceans could rise about 10-12 inches (roughly 25-30 cm) by 2050 compared to the early 2000s. Nature World News
• [New] Red Sea corridor limitations force increased reliance on facilities like Yanbu, which must handle substantially elevated throughput volumes during Persian Gulf route disruptions. Discovery Alert
• [New] LOOKOUT is an AI marine vision system that gives boats SuperSight, an AI-powered hazard detection that sees what radar and human attention routinely miss. Superyacht News
• [New] The Pacific Ocean remains the pre-eminent theater of global maritime risk in 2026, as China's assertive posture in the South China Sea and the Taiwan Strait systematically challenges the remnants of the rules-based regional order. SpecialEurasia
• [New] With China's naval expansion, the Indian Ocean is now the key theater for competition regarding regulatory doctrines and global data transmission, which will shape the future of the Asian era. SpecialEurasia
• [New] For Kiribati and Samoa, which face growing risks from coastal flooding, extreme wave events and changing ocean conditions, the new buoys will help fill critical gaps in ocean observations. Islands Business
• [New] The Northern Sea Route along Russia's coast, the Northwest Passage through Canada's Arctic Archipelago, and the Transpolar Sea Route across the central Arctic Ocean could reduce transit times between Asia, Europe, and North America by up to 40%. Roland Berger
• [New] A global study reveals widespread human-made chemicals in the oceans, while a new campaign and Netflix documentary warn plastic-associated toxins are emerging as a major, under-recognised threat to human health. Oceanographic
• [New] Yemen became a model of peripheral positioning: anticipated Houthi attempts to disrupt Red Sea shipping could be countered through the Somaliland foothold at Berbera, enabling naval interdiction and persistent pressure on supply lines without overextending core forces. HORN REVIEW
• [New] Estimates of total ocean pollution to date typically do not include any contribution from nanoplastic - although as the size of plastic in the ocean skews towards smaller particles over time, we suspect that nanoplastic particles could be a globally important environmental contaminant. Environment
• [New] The Union Budget 2026-27 has announced a comprehensive and far-reaching package of measures to strengthen India's fisheries sector, covering inland and marine fisheries, export competitiveness, coastal livelihoods and value chain integration. Radiance Media
