US power sector would be world’s sixth largest emitter of planet-heating greenhouse gas if it were a country – study Donald Trump’s administration is set to claim planet-heating pollution spewing from US power plants is so globally insignificant it should be spared any sort of climate regulation. But, in fact, the volume of these emissions is stark – if the US power sector were a country, it would be the sixth largest emitter of greenhouse gases in the world. Continue reading...

Israeli forces have taken command of a vessel that tried to circumvent its naval blockade of the Gaza Strip, sending the boat and its crew of 12 – including the activist Greta Thunberg – to a port in Israel, according to officials. The UK-flagged Madleen, operated by the pro-Palestinian Freedom Flotilla Coalition (FFC), was trying to deliver a symbolic amount of aid to Gaza on Monday to raise international awareness to the humanitarian crisis there. However, the boat was boarded by Israeli forces before it could reach the shore, the FFC said. The foreign ministry confirmed that the vessel was under Israeli control Israeli forces take control of Gaza aid boat carrying Greta Thunberg Middle East crisis – latest updates Continue reading...

Chances are, wherever you live, if there’s greenery around there will be owls there too It is dusk, a short walk from the big Ikea in Croydon, and a barn owl is emerging from its nest to hunt. In the fading light, the male owl sits on a fence post to survey the rough grass below. He has a busy evening ahead: he is responsible for feeding a roosting female for the next few weeks while she cares for their chicks. The owl hops to another fence post. Suddenly, he dives into the grass below, emerging a minute later with an unlucky rodent, and flies back into the nest. “I still get really excited,” says Tomos Brangwyn, a local enthusiast who monitors the site, lowering his binoculars. “He’ll do that most of the night. It’s a great sign that there’s a female in there that we haven’t seen for a while, as she’s on the eggs,” he says. Continue reading...

For millions of years, large herbivores like mastodons and giant deer shaped the Earth's ecosystems, which astonishingly stayed stable despite extinctions and upheavals. A new study reveals that only twice in 60 million years did environmental shifts dramatically reorganize these systems once with a continental land bridge, and again with climate-driven habitat change. Yet the ecosystems adapted, with new species taking on old roles. Now, a third, human-driven tipping point threatens that ancient resilience.

Murray Watt tells UN conference in France a review of Australia’s marine parks will ‘lay the foundation’ for increasing ocean protections Sign up for climate and environment editor Adam Morton’s free Clear Air newsletter here The Australian government plans to declare 30% of its ocean “highly protected” by 2030, raising expectations from conservationists it will ban fishing and drilling in nearly a third of the country’s waters. The environment minister, Murray Watt, told the UN Ocean Conference in France a review of 44 of Australia’s marine parks would “lay the foundation” to increase the area of the country’s ocean with higher levels of protection.

Vast areas of land are now dominated by one species – purple moor-grass – and good luck with seeing a bird or insect there. How do we revive these habitats? Deserts are spreading across great tracts of Britain, yet few people seem to have noticed, and fewer still appear to care. It is one of those astonishing situations I keep encountering: in which vast, systemic problems – in this case, I believe, covering thousands of square kilometres – hide in plain sight. I realise that many people, on reading that first sentence, will suspect I’ve finally flipped. Where, pray, are those rolling sand dunes or sere stony wastes? But there are many kinds of desert, and not all of them are dry. In fact, those spreading across Britain are clustered in the wettest places. Yet they harbour fewer species than some dry deserts do, and are just as hostile to humans. Another useful term is terrestrial dead zones. Continue reading...

In seas around the world pH levels are falling – and scientists are increasingly frustrated that the problem is not being taken seriously enough Read more: ‘Ticking timebomb’: sea acidity has reached critical levels, threatening entire ecosystems – study On a clear day at Plymouth marina you can see across the harbour out past Drake’s Island – named after the city’s most famous son, Francis Drake – to the Channel. It’s quite often possible to see an abundance of marine vessels, from navy ships and passenger ferries to small fishing boats and yachts. What you might not spot from this distance is a large yellow buoy bobbing up and down in the water about six miles off the coast. This data buoy – L4 – is one of a number belonging to Plymouth Marine Laboratory (PML), a research centre in Devon dedicated to marine science. On a pleasantly calm May morning, Prof James Fishwick, PML’s head of marine technology and autonomy, is on top of the buoy checking it for weather and other damage. “This particular buoy is one of the most sophisticated in the world,” he says as he climbs the ladder to the top. “It’s decked out with instruments and sensors able to measure everything from temperature, to salinity, dissolved oxygen, light and acidity levels.” Continue reading...

Ocean acidification has already crossed a crucial threshold for planetary health, scientists say in unexpected finding More on this story: How the ‘evil twin’ of the climate crisis is threatening our oceans The world’s oceans are in worse health than realised, scientists have said today, as they warn that a key measurement shows we are “running out of time” to protect marine ecosystems. Ocean acidification, often called the “evil twin” of the climate crisis, is caused when carbon dioxide is rapidly absorbed by the ocean, where it reacts with water molecules leading to a fall in the pH level of the seawater. It damages coral reefs and other ocean habitats and, in extreme cases, can dissolve the shells of marine creatures. Continue reading...

Environmental groups welcome government proposals to clamp down on destructive fishing practice Environmental groups have welcomed government proposals to ban the destructive fishing practice known as bottom trawling in half of England’s protected seas. The plan, to be announced on Monday by the environment secretary, Steve Reed, came before a UN summit in Nice to tackle the ocean’s failing health. It follows pressure from conservationists and the release of a David Attenborough film featuring rare underwater footage of the devastation to the seabed caused by bottom trawling in British waters.

The Last Dive tells how a relationship with a giant Pacific manta ray turned a big game fish hunter into a conservationist Located about 500km off the southern coast of Baja California lies a group of ancient volcanic islands known as the Revillagigedo Archipelago. Home to large pelagic species including whale sharks and scalloped hammerheads, the rugged volcanic peaks were also once the site of an unlikely friendship. It began in December 1988 when Terry Kennedy, a now 83-year-old American sailor with a storied past, met a six-meter-wide giant Pacific manta ray off San Benedicto island’s rugged shore. He would go on to name him Willy. “When I saw him beside the boat, as massive as he was, I just had to get in the water just to see him,” says Kennedy. “I threw a tank on and jumped over, but I didn’t see him anywhere. He couldn’t have vanished that quick. And then I looked straight down and he was coming up underneath me. He was about four feet away and rising so I had no way to get off his back.” Continue reading...
