Dolphins living in the English Channel are exposed to a “cocktail of pollutants”, say scientists. A study found some of the highest recorded levels of toxic chemicals and mercury in the bodies of bottlenose dolphins off the French coast.

Researchers say more needs to be done to tackle the “invisible” problem of lingering pollutants in the oceans.

The Channel is home to one of the last remaining large European populations of bottlenose dolphins.

Researchers took tissue samples from more than 80 dolphins living in waters off Normandy and Brittany.

They found high concentrations of mercury in skin and polychlorinated biphenyls, or PCBs, in blubber.

Other industrial chemicals, such as dioxins and pesticides, were also found in blubber samples, which together may act as a “cocktail of pollutan...

Only a fraction of the marine areas meant to be protected by the European Union are being properly conserved at present, according to a new report. The research – by the World Wide Fund for Nature and Sky Ocean Rescue – says less than 2% of the EU’s waters are being properly managed, compared to the target of over 12%.

Janica Borg from the World Wide Fund for Nature told Euronews’ Good Morning Europe that the aim of the protected areas is very important:

“The aim of protected areas is to conserve biodiversity so that we can ensure that the oceans are conserved for future generations.

“Not only that, it’s also important for a stable blue economy; this means greater use of marine sectors and is something the EU is currently developing.

“Currently, there’s good intentions for protection...

Investing $1.8 trillion over the next decade – in measures to adapt to climate change – could produce net benefits worth more than $7 trillion. This is according to a global cost-benefit analysis setting out five adaptation strategies.

The analysis was carried out by the Global Commission on Adaptation – a group of 34 leaders in politics, business and science.

They say the world urgently needs to be made more “climate change resilient”.

• 12 years to save the planet? Make that 18 months
• Big lifestyle changes needed to cut emissions
• Climate change is ‘shrinking winter’

The commission, led by former UN Secretary-General Ban Ki-moon, World Bank chief executive Kristalina Georgieva and Microsoft co-founder Bill Gates, argues that it is an urgent moral obligation of richer countries to invest ...

A vast “raft” of volcanic rocks stretching over 150 sq km (58 sq miles) is drifting through the Pacific Ocean, scientists say. The sea of pumice – the size of 20,000 football fields – was first reported by Australian sailors earlier this month.

Experts say the mass probably came from an underwater volcano near Tonga which erupted around 7 August according to satellite images.

Sailors have been warned to stay clear of the potential hazard.

Pumice is a lightweight, bubble-rich rock that can float in water. It is produced when lava goes through rapid cooling and loss of gases.

Large “rafts” of the volcanic rock are more likely to form when a volcano is located in more shallow waters, say experts.

• Deep sea volcanoes found off Sydney

It’s a historic week for climate change in the Democratic Party.

In the same 12-hour span, Senator Bernie Sanders unveiled his plan to pass a gargantuan $16 trillion Green New Deal as president, while Governor Jay Inslee of Washington—who ran an unprecedented, bluntly climate-focused campaign—dropped out of the 2020 primary.

Then, this afternoon, the Democratic National Committee rejected a proposal to hold a climate-centered debate in the primary—even though nearly every candidate had endorsed the idea.

The world will have an additional 2 billion people to feed over the next 30 years – and doing that without decimating the planet’s resources will require exploring as many options as possible. Yet, a significant option – seafood – is often overlooked in global food security planning and discussions about future diets.

Stanford Report spoke with Jim Leape, co-director of the Stanford Center for Ocean Solutions, and Rosamond Naylor, the William Wrigley Professor in Earth System Science, about integrating oceans into a sustainable and equitable food future...

Germany says it plans to take a more active role in Arctic affairs, citing the far north’s growing ecological, political and economic significance as a result of climate change.

Cabinet passed a resolution Wednesday declaring its intention to send German experts to advise the Arctic Council. It also plans to campaign for an expansion of environmental protection areas in the Arctic and explore the potential that the increasingly ice-free Northwest and Northern Passages have for shipping during the summer.

German Chancellor Angela Merkel said Tuesday after a meeting with Nordic leaders that her country, which is an observer in the Arctic Council, will “keep an eye on the strategic role of the Arctic.”

Merkel said Germany would seek to prevent the Arctic from becoming “an obje...

Across the turquoise water by the mangrove, forest ranger Allan Halliday spots a fishing skiff. “We’re going over to say hello,” he says, before abruptly changing the boat’s direction. But his real task is to check the couple on board have the licence to fish in this part of the Port Honduras Marine Reserve, one of nine designated zones in Belize.

“We aren’t complaining but others do,” says Alonzo Reymundo, of the rules that now restrict Belize’s 3,000 commercial fishers to two geographic areas each. He and his wife Anselma have been fishing off southern Toledo for 30 years and their boat is laden with 50 or so pounds of shrimp – more than enough, he says, flashing his licence. Today’s catch will be sold as bait and fetch around 330BZ$ (£135), he says.

But not a...

When pollsters informed President Donald Trump that he faces political exposure in the 2020 election with swing voters on environment policy, he decided to respond with a White House address claiming stewardship of clean water, air and oceans.

But as some Trump aides were drafting that speech, others were casting doubt on the significance of a climate threat to a key battleground state: the degradation of coral reefs in Florida.

Weeks before, a senior intelligence analyst at the State Department had submitted a draft of planned testimony to Congress detailing the national security implications of climate change for White House review.

Among the edits that the analyst, Rod Schoonover, received back from the White House was a novel argument...

A team of researchers, led by international conservation charity ZSL (Zoological Society of London), has discovered that sharks are much rarer in habitats nearer large human populations and fish markets. The team also found that the average body size of sharks and other marine predators fell dramatically in these areas, where sharks are caught and killed intensively for their meat and fins.

The study, published today in the journal PLOS Biology, shows that the average body size and number of sharks and other marine predators — vital to maintaining healthy ocean ecosystems — fell significantly in proximity to cities with more than 10,000 people and associated fishing fleets.

The minimum distance from people and fishing which had no measurable effect was 1,250 kilometres...
