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] A new study published in Nature finds that many of the world's largest river deltas are subsiding more quickly than global sea levels are rising, putting hundreds of millions of people at potential risk. ScienceDaily
• [New] The sea will be moderate to rough in the Arabian Gulf and slight to moderate in the Oman Sea. Khaleej Times
• [New] With an investment of $3.8 billion, Canada's new nature strategy will protect and restore critical habitats, including the creation of new national parks, national marine conservation areas, and national urban parks. Mirage News
• [New] Atlantic Ocean currents that are vital for keeping Earth's climate in check will halve in strength by 2100 and may be closer to collapse than first thought, a new study finds. Live Science
• [New] Radionuclides spread across most of western Europe, raising fears of crop contamination as far away as the Lake District, Scotland and Ireland. The Guardian
• [New] With an improved understanding of sediment distribution and carbon storage in the North Sea, we can assess long-term risks to coastal stability, navigational safety in shipping, and the functioning of ecosystems in the German Bight. SciTechDaily
• [New] Offshore wind energy is central to the European Union's renewable strategy, with plans to boost North Sea capacity more than tenfold by 2050. SciTechDaily
• [New] Amoc's shutdown is likely to cause an acceleration of sea level rise on the east coast of the US, threatening cities. The Guardian
• [New] Fastest Growing Segment: Marine & Shipping is the fastest growing end-use segment, propelled by the IMO 2023 Strategy mandating 40% carbon intensity reduction by 2030 and net-zero by 2050, creating a structured, deadline-driven procurement pipeline for high-power marine hydrogen combustion engines. Persistence Market Research
• [New] Coastal heritage faces escalating exposure to sea-level rise, flooding and erosion, with documented risks to World Heritage properties. Nature
• [New] Through the Kunming-Montreal Global Biodiversity Framework, agreed in 2022, governments have pledged to halt biodiversity loss, protect at least 30% of land and oceans by 2030, and restore degraded ecosystems. Greenpeace International
• [New] Around 80 million people are today living on land in coastal areas below sea level - almost twice previous estimates - dramatically increasing the numbers at risk as sea level rise accelerates in the coming decades. Yale E360
• [New] Data from tidal gauges shows that actual sea levels worldwide are on average 9.4 to 10.6 inches higher than predicted by models. Yale E360
• [New] As the world continues to warm, every marine heat wave will be warmer than the last one. Los Angeles Times
• [New] An extreme marine heat wave is simmering the Pacific Ocean off the coast of California, and experts are warning that it could affect coastal weather and ecosystems for months. Los Angeles Times
• [New] The glaciers of Canada's Arctic have been losing mass at an accelerating rate over the past several decades, contributing an estimated 0.3 to 0.5 millimeters per year to global sea level rise in recent years, a contribution that is expected to grow as warming continues. OREACO
• [New] Cooler-than-normal conditions (1 °C below average) are expected across the Black Sea region over the next 10 days, followed by warmer weather mainly affecting eastern Ukraine, Russia, and the northern Kazakhstan crop belts. ADMISI
• [New] The Black Sea region is expected to experience dry conditions (up to 15 mm below normal), while wetter conditions will be confined to southern Ukraine, the North Caucasus, and Turkey during the next 15-day outlook. ADMISI
• [New] Low water levels create land bridges to river islands, allowing predators like jackals and dogs to destroy the nests of threatened birds like the Indian skimmer and black-bellied tern. INSIGHTS IAS - Simplifying UPSC IAS Exam Preparation
• [New] Retrofitting legacy lighting systems presents a major growth opportunity, particularly as a large share of global marine and small-vessel fleets continues to rely on outdated incandescent and halogen technologies. Persistence Market Research
• The majority of the Arctic Ocean could be ice-free during summer by 2050, but as the length of a polar bear generation is about 11.5 years, genetic adaptations to an ice-free ecosystem will likely take many hundreds or thousands of years. Live Science
• Ammonia will account for 8% of marine fuel demand in 2030, rising to 46% by 2050, indicating that demand for ammonia-powered vessels is expected to grow significantly. Cision PR Newswire
