Wayland Wood, Norfolk One of the things I love about ash is its reluctance to give up lifeThe proximity of a busy road to such a glorious fragment of Domesday England is one of my only regrets about Wayland. I also wish this t1000-year-old wood were five times bigger. There is at least consolation in its ownership by the Norfolk Wildlife Trust and in its regime of wonderfully restrained untidiness. At times it feels as if there’s as much dead wood on the ground as there is canopy overhead.The bluebell carpet is all succulent green and there are exquisite clusters of pale lemon laagered in the crinkle-leaved primrose patches. Yet this is still a wood locked in winter. The most magnificent and deadest-looking of all Wayland’s trees are the ash. The trunks are bone coloured and bone smooth and, while the hazels’ wands have bark that is smoother, they are festooned in swinging catkins and emblematic of a different season. Continue reading...

‘I wish him well,’ former party leader says of Geoff Holloway’s plan to form breakaway groupThe former Greens leader Bob Brown has shrugged off the impact of a split in the Tasmanian Greens that will lead to a breakaway faction contesting the state election.“I hope they win every dark green vote in Tasmania – they’ll go straight across to the Greens in preferences,” he said.

Study finds protecting a single type of herbivorous fish could be crucial to the recovery of reefs from damage related to climate changeLimiting the take of just one type of fish could protect coral reefs around the world from the most serious immediate impacts of climate change, researchers have found.Studying Caribbean coral reefs, Peter Mumby and colleagues from the University of Queensland found that enforcing a rule limiting the fishing of a single type of herbivorous fish – parrotfish – would allow coral reefs there to continue to grow, despite bleaching and other impacts associated with climate change.

Exclusive: The revenue the federal government would lose if it stopped all new or expanded thermal coal and gas projects has dropped by 80% in 2.5 yearsAs the fossil fuel industry appears increasingly shaky, the cost to the federal budget of stopping all new coal and gas projects in Australia has plummeted – costing less than 20% of what it was estimated to just 2.5 years ago, according to official parliamentary costings seen by Guardian Australia.The Greens have a policy of approving no new thermal coal or unconventional gas projects in Australia. That includes new mines, as well as expansions to existing mines. Continue reading...

Leak in pipeline being built by energy giant Spectra could lead to shutdown – or worse – at the New York state power station, experts sayAcross a narrow swath cut by bulldozers and chainsaws through the woods of Westchester County, New York, triangular yellow flags are clotheslined between pairs of trees. The flags trace the eventual path of the gas pipeline that the energy giant Spectra is building through the area, escorted at times by police and harried by local residents worried by its proximity to a decaying nuclear power plant.If that pipeline leaks or breaks, say experts, its contents could detonate and destroy the switchyard that sits 400ft from the gas line. Entergy, which runs the Indian Point power station, said the plant could be quickly shut down in such an event. Nuclear engineer Paul Blanch is not so sure. Blanch, who has previously consulted for Entergy and now assists an organization calling for the pipeline to be stopped, said that assertion is a best-case scenario. In the worst case, he said, the reactors could melt down. And he believes Entergy and Spectra have not fully considered that worst-case scenario. Continue reading...

The Spectra Energy pipeline expansion has been given the go-ahead, but inadequate safeguards make me scared for my children’s healthThe Keystone XL pipeline was vetoed by President Obama last year as being antithetical to the nation’s climate goals. Yet fights against pipelines continue to rage across the country – including 400 feet from my home in New York state, where a proposed pipeline next to the troubled Indian Point nuclear plant has spurred fears of a Fukushima-like scenario, with New York City lying squarely in an evacuation zone.

Thin film of red dust enveloping parts of country for two weeks in 2014 came mostly from farms in mainland Europe and local emissions, study saysBritain’s most serious air pollution event in the past 10 years was only partly caused by “natural” dust blowing in from the Sahara desert and mostly came from farmers fertilising their fields and industrial emissions from mainland Europe, a scientific paper has concluded.

Environment and forestry minister Siti Nurbaya denies reports authorities will deny Oscar winner entry if he keeps making pro-environment statementsAn Indonesian minister has denied reports the country could move to blacklist Leonardo DiCaprio after the Oscar-winning actor criticised the environmental impact of palm-oil cultivation on a recent visit to the Sumatran rainforests.On Saturday the Associated Press reported comments from Heru Santoso, spokesman for the directorate general for immigration at Indonesia’s law and human rights ministry, who said DiCaprio’s recent visit to the Leuser Ecosystem in northern Sumatra had been used to discredit both the palm-oil industry and the nation’s government.

The Southern Fells, Lake District Looking at the clear tops above, I feel like a kid waiting to get at his presentsI am just about to duck instinctively when whatever is heading straight at our heads banks sharply and misses us by metres, its yellow-rimmed eyes fixed upon us as it flies. Its chest is the colour of snow and stone and unmistakable.There almost seems to be a moment of mutual surprise between us and the peregrine. After shooting over a rocky brow, it drifts easily through the wide expanse of Langdale, like an arrow that has achieved sentience after release and gone its own leisurely way. Continue reading...

Demonstrators outside Queensland’s Parliament House chant ‘reef not coal’ after Adani clears regulatory hurdleThe Queensland government’s approval of leases for Adani’s Carmichael mine, Australia’s largest proposed coal project, was “economic stupidity and environmental insanity”, a protest rally heard on Monday.The Queensland Greens Senate candidate and former Australian Democrats leader Andrew Bartlett told the demonstration outside Queensland’s parliament house the approval could jeopardise the Greens preferences that had helped bring the Palaszczuk government to power.

On 25 April it will be the first anniversary of Nepal’s Gorkha earthquake – the country’s worst natural disaster since the 1934 Nepal-Bihar earthquake. The magnitude 7.8 quake killed over 9,000 people and injured over 23,000. With prior warning many of those lives could have been saved. Most seismologists believe that predicting earthquakes is impossible. However, Friedemann Freund, a researcher at NASA believes he has found a subtle signal emitted in the hours before the tremors start.A mineral physicist by background, Freund’s idea originated from attempts to produce electricity by putting rocks under stress. In 2006 he showed that a block of granite under pressure could produce an electrical current, due to mineral defects unsettling electrons. By 2009 he showed that this process caused air molecules to ionise above the surface of the rock. At that point he wondered if the build-up of stress prior to an earthquake would ionise the air molecules above the fault. Ian Main, an earthquake scientist at the University of Edinburgh, is skeptical of the hypothesis. “The problem is how these processes scale to the much larger spatial and temporal scales in a much more complex material involved in earthquakes,” he says.

Artists, scientists and politicians sign letter to Guardian calling on museum to end ‘out of touch’ partnership with oil firm

Letter from Margaret Atwood, Mark Ruffalo, Mark Rylance, Tom Kibble, Naomi Klein, Emma Thompson, Vivienne Westwood and othersWe congratulate Dr Hartwig Fischer on his new role as director of the British Museum (Profile, 1 April), and would like to take this early opportunity to raise an ethical issue of great concern to us all. As the impacts of climate change are being felt more forcefully around the world, it is vital that prominent public institutions like the British Museum play their part in minimising the environmental impacts of their activities.BP’s sponsorship contract with the museum is coming to an end this year. While governments in Paris committed to transition away from fossil fuels, BP remains a barrier to progress. It is working to extract new sources of carbon-intensive oil from the tar sands, the Arctic and under the oceans, when we need to keep at least two thirds of known fossil fuels in the ground. BP’s business plan is incompatible with a stable climate, and the company is using its influence to lobby against effective climate policies. Continue reading...

If the EU can’t save Białowieża from the loggers, its protections are meaninglessBiałowieża is “the misty, brooding forest that loomed behind your eyelids when, as a child, someone read you the Grimm brothers’ fairytales”, in the words of American ecologist Alan Weisman. This unique place of towering hornbeam and fungi the size of dinner plates is Europe: 1,500 sq km of woodland on the border of Poland and Belarus is the last lowland remnant of what covered our continent after the ice age. It is home to 20,000 species, including 12 carnivores such as lynx and wolves, 120 species of breeding bird such as the three-toed woodpecker and rare insects and invertebrates that were lost to the rest of Europe a century or more ago.The forest boasts Europe’s tallest trees and largest mammal, the bison. It is a national treasure for Poland and an international treasure for us all. Białowieża is our past and our future, a natural laboratory for the study of species and climate, providing globally useful insights into how we’ve changed our environment and how it is changing afresh. Only a small portion (16%) is a national park and parts are protected by the EU and as a Unesco world heritage site. Continue reading...

Critics question why so many companies have been set up at Mayfair base of China’s state-owned nuclear power firmBeijing’s growing confidence in its plans to help build new reactors at Hinkley in Somerset and Bradwell in Essex has been underlined by the recent incorporation of seven new Chinese nuclear-related firms in London.It appears, however, that an agreement between China and its partner EDF of France to develop the first new reactors in Britain for 20 years has still not been signed.

On Poland’s far border lies Białowieża, one of the last remnants of Europe’s primeval forest. It’s a haven for birds and mammals, but it’s also under threat, as our writer discovered on a new tripThe Polish border with Belarus, on the eastern edge of the EU, may not seem an obvious holiday destination but there, largely unknown to British travellers, lie two amazing destinations for nature lovers. Białowieża forest, which straddles the border, is the last extensive stretch of the primeval forest that once covered all of north-east Europe, while, 100km to the north, the Biebrza marshes are among the continent’s most important wetlands.These two national parks are almost the only places where Europe’s original landscape and wildlife can be seen. But Białowieża forest has become a new kind of front line, between environmentalists and the Polish government, which this week gave the go-ahead to large-scale logging. Continue reading...

Musicians’ love affair with tonewoods such as mahogany and and ebony plays mayhem with sustainability – and synthetic materials sound just as goodThe tag “rock’n’roll royalty” should really belong to the instruments: the backstory of some of the world’s best acoustic guitars is frankly breathtaking. Take Bedell’s Antiquity Milagro Parlor guitar. It’s carved from a 400-year-old Brazilian rosewood tree. Wandering troubadours who possess one should make sure they have their “guitar passport” handy, otherwise their instrument could be confiscated by customs officials under trade-in-endangered-species laws.Many other guitars sold each year (nearly 3m in the US alone) are also made from rare timber. Thanks to musicians’ bias for tropical tonewoods – particularly mahogany, rosewood and ebony – this is a market in which the illegal timber trade can flourish. That’s anything but harmonious when you bear in mind that every two seconds an area of forest the size of a football field is clear-cut by illegal loggers. Continue reading...

Bruni’s taps deliver poison to its poor, largely Hispanic residents but other rural towns in the state suffer with water that is black, brown or stinks of rotten eggsJulio Perez sprayed his yard with water from a garden hose. While the flowers were no doubt grateful for the refreshment on a warm afternoon, there was no chance of him quenching his own thirst with a gulp of tap water.The 66-year-old lives in Bruni, a tiny Texas town notable for a very unwelcome reason: the quantity of arsenic in its water. In 2014-15 the average concentration of the carcinogen was 79.6 parts per billion: almost eight times the federal limit. Continue reading...

Collusion between private sector and government exacerbating problems, says corruption official

I’ve been making plans for yet another in the string of springs that I never expected to seeIn the oncology clinic at Addenbrooke’s, my latest blood test went pretty well, but I got a bit down in the mouth anyway, because for someone in my condition, even a good result is a reminder that you have to go on throwing a double six to stay in the game. In the cab home, however, gloom was soon dispelled by the sight of the flowers in the lawns of the college “backs”, so called to help foreign visitors grasp the Cambridge concept of a back yard that looks better than anybody else’s front yard.Some of the daffodils had been on display for weeks, but now they had tripled their numbers and were being joined by searching bursts of crocuses, erupting like Byzantine tracer through the grass. Or perhaps Botticelli’s Primavera girl had just gone dancing through, or Matilda from Dante’s Earthly Paradise. Or perhaps they were just crocuses. Good of them, though, to arrive just in time for me to notice. Continue reading...

Borth, Ceredigion The stumps rise from clots of dark peat lying on boulder-clay and held together by a lattice of blanched rootsSmall waves hissed into the pebbled shore, clacked stone against stone as I made my way to the drowned forest. One of many around the coasts of Wales (a particularly fine example lies just beyond the east end of Rhyl’s promenade), that at Borth has become more prominent since storms in 2014 scoured away covering sand, which in time will conceal it again.

About 200 people rode on horseback to protest against pipeline that encroaches on tribal lands and could pollute Missouri river: ‘We’re looking out for all people’Dozens of tribal members from several Native American nations took to horseback on Friday to protest against the proposed construction of an oil pipeline which would cross the Missouri river just yards from tribal lands in North Dakota.The group of tribal members, which numbered around 200, according to a tribal spokesman, said they were worried that the Dakota Access Pipeline, proposed by a subsidiary of the Dallas, Texas-based Energy Transfer Partners, would lead to contamination of the river. The proposed route also passes through lands of historical significance to the Standing Rock Lakota Sioux Nation, including burial grounds. Continue reading...

Whale experts discover orca they know as Comet is same killer whale that swam into Northern Irish city nearly 40 years agoA killer whale that sparked widespread attention when it swam into a Northern Irish city almost 40 years ago is still alive and living off the west coast of Scotland, experts have found.The whale was nicknamed Dopey Dick by locals after he made his way up the river Foyle into the heart of Derry in pursuit of salmon in 1977. He is now thought to be at least 58 and was identified when pictures of the Irish incident were compared with images taken of a pod of whales near the Isle of Skye in September 2014.
