Science
The Atlantic’s key ocean current may be more likely to collapse than previously thought.
Climate change is placing growing pressure on marine wildlife, with shrinking Antarctic sea ice threatening emperor penguins and fur seals through habitat loss, while rising ocean temperatures are also increasing risks for warm‑bodied sharks and tunas.
Whales often reduce their vocalisations during noisy seismic surveys because the intense underwater noise disrupts their communication.
Fisheries
UK fish stocks such as cod and mackerel are being pushed towards collapse by continued overfishing. For 2026, the UK Fisheries Minister set 58 per cent of catch limits above levels recommended by scientific advice. Despite this, a Defra spokesperson said “our approach to setting catch limits is based on the best available scientific advice” – an evident contradiction. The UK should take note of the highly effective U.S. Magnuson-Stevens fisheries law, which turns 50 this year.
A new study suggests the Marine Stewardship Council’s “blue tick” label can give consumers a misleading sense of sustainability and ethical sourcing, even where serious labour abuses persist within parts of the seafood supply chain.
The UK Government has been urged to take stronger action on ghost fishing gear, with campaigners saying they feel like they are “banging on a closed door” when dealing with Defra and the MMO.
UK Overseas Territories
The UK has paused the Chagos Islands deal after Donald Trump’s opposition, halting plans to transfer sovereignty to Mauritius and lease back the Diego Garcia base.
Emperor penguins and Antarctic fur seals are now endangered due to climate change-driven loss of sea ice and food shortages, with both species showing sharp population declines, while similar pressures are affecting wildlife around South Georgia.
Seasonal fishing restrictions have come into effect in Bermuda, temporarily closing certain reef areas to allow species like red hind and grouper to reproduce and help maintain fish stocks.
Marine Protection
Ghana has established its first marine protected area, covering around 703 sq km off Cape Three Points.
Tracking data from camera-equipped Adélie penguins in East Antarctica shows they eat a wider range of prey than previously known, including small shelled marine organisms like pteropods.
An increasing number of grey whales are being killed after collisions with ships near San Francisco, raising concerns about the growing risks posed by heavy marine traffic to the species.
Research suggests that improving and restoring river plant habitats could be key to supporting declining Australian lungfish while also benefiting overall freshwater ecosystem health.
A humpback whale stranded in the Baltic Sea has been deemed beyond saving, with rescue efforts unsuccessful and experts saying “we are totally out of our depth” as the situation worsens.
Conservation
Conservationists are increasingly using drones to monitor and protect dugongs.
Nearly half of the world’s large freshwater animals are now living well outside their natural habitats.
Studies suggest that sperm whales communicate using structured click sequences that act like basic sound units, organised in a way that parallels the role of vowels in human speech.
A walrus has been spotted coming ashore on a Scottish island, marking a rare return after an absence of around eight years.
Climate Crisis
Scientists have created a new picture of how ocean pollution is spread globally, by analysing mercury levels in seabirds.
BP is facing legal action in Kenya over accusations that hazardous waste left behind by oil exploration in the 1980s has caused lasting harm to people and the environment.
Microplastics are disrupting the activity of small sediment‑dwelling organisms that help regulate coastal ecosystems.

“Discovery is inevitable. The tragedy before us now lies in rushing to exploit the deep sea before we understand what we could lose.”
“Honestly, what struck me wasn’t necessarily just Earth, it was all the blackness around it. Earth was just this lifeboat hanging undisturbedly in the universe.”
