A California town’s beaches are washing away. Can its residents turn the tide?

Rapid coastal erosion threatens coastal homes and economies, and as Super El Niño rounds the corner, a town is reckoning with the reality of climate crisis

San Clemente is one of southern California’s most picture-perfect beach towns – a capital of American surf culture since the 1950s. In two years, 2028 Olympic surfers will compete at Lower Trestles, a world-class surfing beach.

But the town’s longtime cultural and economic driver, its beaches, are now under threat. As pounding waves driven by late-summer storms in the Pacific devour chunks of the California coastline, some of San Clemente’s beaches are growing narrower, the sand increasingly eaten away.

While anglers cannot take endangered sand tiger sharks, a loophole lets private firms catch the fish to sell abroad, profiting from Delaware Bay’s conservation success

Shortly after 12.45pm, what remains of a 300-metre line goes taut. Somewhere beneath the murky green surface of Delaware Bay, on the eastern US coast, a sand tiger shark has taken the bait of a mackerel chunk. Marine researchers at the University of Delaware haul the line towards a small boat as the shark’s grey-brown outline emerges.

It is a large animal: 225cm (7ft) long with a 90cm girth. Its mouth hangs open, revealing rows of jagged teeth. The researchers work quickly, measuring the shark, recording its sex, and taking blood and muscle samples. A tag is then fastened beneath its dorsal fin, through its thick sandpapery skin.

Despite the expansion of Starlink and other communications satellite services, most of the world’s Internet traffic still travels through subsea cables crisscrossing the ocean floors. Those fiber-optic cables coexist with a network of oil and gas pipelines and submarine power cables—and all these crucial links connecting countries and continents now face growing sabotage risks as gray-zone warfare and open conflicts have become widespread.

The rising risks to the world’s invisible infrastructure beneath the waves are the main subject of a new book by Elisabeth Braw, a senior fellow at the Atlantic Council who leads the Threats to the Global Maritime Order Initiative. Her book, titled Undersea War, explores the modern rise in suspicious incidents in which ships dragging their anchors for unusually long periods have cut or damaged undersea cables and pipelines, from the Baltic Sea to the Pacific Ocean.

Braw acknowledges that about 60 percent of undersea cable damage is primarily due to human error during fishing and shipping activities, when weighted nets or anchors drag across the seabed. Natural hazards like storms and undersea landslides also account for a smaller proportion of such incidents. In total, between 150 and 200 cables are damaged each year and usually repaired quickly.

Team works to restore the sunflower sea star as 95% of these key underwater ecosystems have been decimated along the Pacific coast in past decade

Off the coast of Monterey, California, a team of researchers is gearing up for its first dive of the day into the cold and choppy waters of the Pacific Ocean.

On the back deck of the boat, Ashley Kidd, a co-founder of the non-profit Sunflower Star Laboratory, gave the divers their final command: “Dive No 1 … stars in the water.”

Changing tide levels, shifting sands and hardened shorelines put waves at risk, affecting more than just surfers

The climate crisis is coming for some of the world’s greatest surf breaks, submerging some as sea level rises and wiping out others as classic breaks get crushed against coastal developments.

Analysis of dozens of famous waves in world surfing reserves (WSR) found more than three-quarters were at high risk because of changing tide levels, hardened shorelines and shifting sands.

Exclusive: Firms made more than £340m last year from processing industrial and commercial wastewater at sewage works that are unable to remove many chemical pollutants

Water companies in the UK made more than £340m in revenue last year by pouring billions of litres of industrial and commercial wastewater into sewage treatment works that experts say are not designed to remove most chemicals, leaving pollutants to pass into rivers, seas and farmland.

Water companies in England are required by law to take industrial wastewater and issue permits called “trade-effluent consents” that allow businesses to send it to sewage works, though water companies can refuse applications.

This is one of Norway’s most pristine fjords. So why is it being used as a dumping site for mine waste? 8 October 2026 at 00:00

The Norwegian government has given a permit to a mining company to release waste into Førde fjord despite a 17-year battle by campaigners and a supreme court ruling against it

Shortly after the Norwegian stock market closed on 17 June 2026, a few dozen local people from the small west coast town of Vevring crowded around a laptop in a school. Surrounded by children’s drawings and windows looking out over Førde fjord, they listened as news arrived from Oslo. Norway’s supreme court had ruled against its government: a permit to release mining waste directly into the fjord two miles upstream was illegal, the court said.

The moment marked the end of a 17-year fight, one of Norway’s most protracted environmental battles in living memory. In Oslo, Ingvild Fonn Asmervik, the project leader for Naturvernforbundet (Friends of the Earth Norway), compared the joy she felt to giving birth to her child. For Anne-Line Thingnes Førsund, a third-generation fisher living on the banks of the fjord in Vevring and a volunteer for the charity’s local branch, it was more of a relief. Like a mountain lifting off her shoulders, she said.
