Plastic is ubiquitous around the world's oceans, writes Lesley Henderson, but although it's visible from space, it can be surprisingly elusive in the water - as she heard from Jo Ruxton, producer of the investigative documentary 'A Plastic Ocean'. Solutions to this growing hazard have also proved elusive to date, hence the film's strong focus on action: educational, cultural and legal.
The Vezo, Madagascar's indigenous 'sea nomads', are travelling hundreds of miles to the remote 'Barren Isles', the Indian Ocean's largest locally-managed marine protected area, writes Charlie Gardner. Drawn by valuable shark fins and sea cucumbers, sold into Chinese markets, the Vezo are now joining with local fishers to protect the ecosystem and expel illegal divers.
The renewable energy revolution is in full swing, writes Jeremy Leggett, with costs falling to new lows, deployment of wind and solar surging to unprecedented highs, and confidence ebbing away from fossil fuels. But global warming is also accelerating, with global temperature records broken every month for a year. Will the energy transition happen in time to avert catastrophe?
The Rampal coal power plant in Bangladesh, near the world's greatest mangrove forest, is a deeply misconceived project that must be abandoned, writes Johan Frijns in this Open Letter to the Exim Bank of India - which is planning to finance its construction. It would severely damage the precious local environment and wildlife, while adding to global climate change and sea level rise.
Scientists are rightly getting worried about increases in the average sea level over coming years, decades and centuries, writes Mikis Tsimplis. But that's only one cause of sea flooding and the loss of land to the sea. What's often forgotten are intense sea storms, hurricanes, typhoons and shifting tides, which have huge implications for the future of coastal areas around the world.
The deliberate misrepresentation of climate science in our media deserves an urgent corrective, writes John Krebs. Recent misreporting by The Times - passing off partisan, unscientific, non-peer reviewed, ill-informed climate change-sceptic opinion as 'science' - deserves particular opprobrium.
Tidal lagoons could generate 8% of the UK's electricity, writes Stephen Tindale, and go on doing so for 120 years to come. With the Hinkley C nuclear project looking ever more dicey, and with promises to shut down coal fired generation by 2025, a promised new tidal lagoon In Swansea Bay would come in very useful. So why hasn't the government included it in the Energy Bill?
A small fishing community in Mexico's Baja California is playing involuntary host to a gigantic tourism and real estate development, writes Viviane Mahieux. And while the branding of the Tres Santos resort is all about mindfulness, ecology and sustainability, the reality is one of big money, high level politics, and the unaccountable deployment of state violence against those who dare oppose it.
This week, the International Maritime Organisation could act to curb fast-rising emissions from shipping under the Paris Agreement, write Barry Gardiner & Richard Burden. But there are growing fears that the UK government may seek to delay and obstruct vital progress.
BP's plans to explore for oil in the deep seas of the Great Australian Bight came under fire today at the company's Annual General Meeting in London, writes Graham Readfearn. The drilling would risk the ocean's rich marine wildlife - while blowing a massive hole in Australia's COP21 emissions targets.
Large areas of the Great Barrier Reef are dying in what may be its greatest ever 'bleaching' event, writes James Dyke. The mass loss of the photosynthetic algae that sustain the coral is the result of this year's massive 'El Niño' perturbation to Pacific weather patterns, and global warming. Australia's response? The government has just approved leases for the world's biggest coal mine.
Of all the impacts of climate change, one stands out for its inexorable menace, writes Pete Dolack: rising oceans. And it's not just for distant future generations to deal with: new scientific studies show that people alive today may face 6-9 metres of sea level rise flooding well over a million sq.km including many of the world's biggest cities. So where's the emergency response?
The giant waves that hit Cornwall's coast this weekend form part of a long term trend, writes Tim Radford. Extreme weather linked to global warming is leading to more violent and more frequent storms devastating beaches, ports, infrastructure and coastal communities on Europe's exposed Atlantic coastlines.
New research from Australia's Great Barrier Reef shows that no-take marine reserves don't just mean more and bigger fish, write Camille Mellin, Aaron MacNeil & Julian Caley. They also boost the resistance of reef communities to disturbances like storms, bleaching and predation, and speed their subsequent recovery. It's time for global rollout of coral reef marine reserves!
Precious World Heritage Sites that protect vital biodiversity and human cultures are at risk from oil decelopment and other industries. Under threat are not just nature, wildlife, land and water but the 11 million people who depend on the 114 sites' environmental quality for their livelihoods.
The dolphin drive hunts in Taiji, Japan have officially ended for the season, writes Ric O'Barry, however the offshore pilot whale hunt continues until the end of May. After a particularly brutal year, which culminated in my arrest and deportation from Japan, we at Dolphin Project will continue our crucial work to end the annual barbarity of cetacean killings and captures.
A coalition of fishing, consumer, and environmental groups are suing the FDA for its 'unlawful' approval of Aquabounty's GM salmon, as it relied on treating the fish as an 'animal drug' under a 1938 law, and ignored serious risks to wild salmon and fishing communities.
The much-derided Common Fisheries Policy must be one of the EU's most unpopular aspects, write Bryce Stewart & Griffin Carpenter. But in fact it has been a notable success, reflecting public concern over bycatch discards and restoring sustainability to Europe's fishing grounds, and profitability to a long declining industry.
The term 'global warming' has a reassuring, comfortable sound, writes Jim Hansen. But paleoclimate data shows the reality could be anything but, with rapid climate oscillations, large, abrupt rises in sea level, major disruptions to ocean circulation, and massive superstorms. It may already be too late to forestall this dystopian future - but then it may not be. So let's act while we still can!
Two heavily armed, UK registered ships are currently engaged in the transport of UK sourced plutonium across the Pacific, writes Tim Deere-Jones. Details of their safety inspection records, survey status, voyage routes and location have been suppressed in the interests of security but the lack of transparency breaches a number of international safety standards.
A legal principle dating from Roman times is ripe for use in protecting our waste-filled and over-exploited seas and oceans, writes Deb Wright. Under the 'Public Trust Doctrine' governments are entrusted to protect shared natural resources from abuse, and can be held accountable for neglect of their duties.
One of the biggest threats facing marine life is the 'microplastic' particles found in ocean ecosystems from bottom to top of food chains. Just back from a voyage of environmental exploration in the tropical Atlantic sampling the waters to build up a global picture of this ubiquitous pollutant, Ana Stanič writes of the joys and trials of life on the waves, and the need to keep our oceans clean.
Mexico's tourist resort of Cancún has just lost one of its greatest natural riches, writes Miguel Rivas: 57 hectares of species rich mangrove forest, bulldozed in a massive overnight attack by property developers in league with local officials. But people power can still win the battle and see the Tajamar mangroves restored.
High levels of toxins mercury and cadmium have been found in all organs of the whales recently beached on Scotland's North Sea coast, including the brain. The research shows that rising mercury levels in the oceans leads to toxic stress in the long-lived marine mammals.
