Large tortoiseshells breeding at Knepp, Sussex, after being officially extinct in Britain for half a century

An elusive butterfly that has been officially extinct in Britain for more than half a century has been discovered breeding on the rewilded estate of Knepp in West Sussex.

The large tortoiseshell mysteriously vanished more than 50 years ago but this week male and female butterflies – much larger than the small tortoiseshell and without its white patterning – have been spotted at Knepp for the first time.

Contract price is nearly 6% lower than previous auction in 2019, which could ease pressure on energy bills

The price of offshore wind power in the UK has fallen to an all-time low, which could ease the pressure on future household energy bills.

Following the biggest ever UK renewables auction, the government said on Thursday the contract price for windfarms was nearly 6% lower than the previous auction, despite the rising cost of materials to build windfarms.

Scientists call for limits on mining as study finds noise pollution could travel for hundreds of miles and from surface to sea bed

Noise pollution from proposed deep-sea mining could radiate through the ocean for hundreds of kilometres, scientists predict, creating a “cylinder of sound” from the surface to the sea bed.

An analysis by scientists from Oceans Initiative in the US, the National Institute of Advanced Industrial Science and Technology (AIST) in Japan, Curtin University in Australia and the University of Hawaii, published in the journal Science, has found that noise from one mine alone could travel 500km (more than 300 miles) in gentle weather conditions.

Particles found in supermarket products and on Dutch farms, but human health impacts unknown

Microplastic contamination has been reported in beef and pork for the first time, as well as in the blood of cows and pigs on farms.

Scientists at the Vrije Universiteit Amsterdam (VUA) in the Netherlands found the particles in three-quarters of meat and milk products tested and every blood sample in their pilot study.

Scientists say numbers of world’s second-largest animal have slowly improved since 1970s whaling ban but sightings in Antarctic feeding grounds are rare

For the first time since whaling was banned, up to 150 southern fin whales have been filmed feeding together in a “thrilling” Antarctic spectacle, hailed by scientists as a sign of hope for the world’s second-biggest animal.

The ocean giants are second only to blue whales in length, with slender bodies that help them glide through the water at high speed.

Russia’s invasion of Ukraine has exacerbated a desperate situation. Famine is not inevitable – but action must be swift

Hunger is stalking the world. Seven years ago, the United Nations vowed to eradicate it by 2030. Yet the number of people affected globally reached 828 million last year, and an unprecedented number – 345 million – are currently experiencing acute food insecurity, the UN has warned.

Covid-19 and the climate emergency had seen that tally rise from 135 million people before the pandemic to 276 million by early this year, reflecting a 55% increase in the Food and Agriculture Organization’s food price index since May 2020. “We thought it couldn’t get any worse,” said David Beasley, head of the World Food Programme.

People living in regional areas are at risk of becoming the “last people in the world” left driving petrol cars because incentives for electric vehicles have been targeted towards city drivers.

Most EVs on the market are likely to have the battery range needed for those living long distances from urban centres, however Australian policy is currently geared only towards encouraging uptake among citydwellers, new research from the Australian National University has found.

Dairy farmers are warning that a chronic shortage of workers is hitting milk production and further fuelling food price inflation, and are calling for urgent action to stop the situation getting worse.

Eight in 10 farm owners looking for workers said they had received very few or zero applications from people with the right experience or qualifications, in response to a survey by Arla Foods, the UK’s largest dairy co-operative.

The prospective new chair of the Environment Agency is refusing to divest his shareholding in a hydrogen and carbon capture company chosen for a major government project.

Energy markets and electricity systems are complicated beasts at the best of times, but throw in war, extreme weather, policy dysfunction and a pandemic and the picture gets even murkier.

However, some of Australia’s conservative commentators seem to think there is one thing to blame for the country’s rising electricity prices and the threat of power outages: it’s all the fault of “net zero”.

University of Cambridge researchers find amphibians dwelling as high as 3 metres above ground

Scientists hunting for dormice have been surprised to find toads sleeping in their nest boxes, high up in the trees.

A study has for the first time revealed the frequency with which the common toad nests and breeds in the trees.

A 2013 storm toppled the tree that had stood in the Ceiriog valley for 1,200 years – but now it lives on

On a stormy night in April 2013, a resounding crack echoed around a valley in north-east Wales and when day broke a melancholy sight met the eyes of villagers.

The mighty Pontfadog oak, a glorious tree that had stood sentinel over the Ceiriog valley for 1,200 years, had been toppled, and a heap of broken branches, decayed wood, lichens and fungi lying among the spring flowers.

Parliament backs plan to classify some projects as clean power investments

The European parliament has backed plans to label gas and nuclear energy as “green”, rejecting appeals from Ukraine and climate activists that the proposals are a gift to Vladimir Putin.

One senior MEP said the vote was a “dark day for the climate”, while experts said the EU had set a dangerous precedent for countries to follow.

Biden’s election was billed as heralding a ‘climate presidency’ but congressional and judicial roadblocks mean he has little to show

Joe Biden’s election triggered a global surge in optimism that the climate crisis would, finally, be decisively confronted. But the US supreme court’s decision last week to curtail America’s ability to cut planet-heating emissions has proved the latest blow to a faltering effort by Biden on climate that is now in danger of becoming largely moribund.

The supreme court’s ruling that the US government could not use its existing powers to phase out coal-fired power generation without “clear congressional authorization” quickly ricocheted around the world among those now accustomed to looking on in dismay at America’s seemingly endless stumbles in addressing global heating.

Officials investigate irregularities in poultry and pig waste exports to Ireland, as ammonia risks turning soil into a ‘wasteland’

Ireland has become a “toilet” for cross-border pollution, say campaigners, as officials investigate allegations around the movement of animal manure from Northern Ireland.

Northern Ireland has the highest stocking density of livestock in the UK, with 25 million poultry birds, and intensive pig numbers at a 10-year high. But the disposal of animal waste and increasing levels of pollution may now halt the expansion of its multi-billion pound export-driven industry.

Protesters from the coalition have staged disruptions at major British museums five times in the past week

Five supporters of the Just Stop Oil coalition have glued themselves to a 500-year-old depiction of The Last Supper in London’s Royal Academy, the fifth time in a week that it has disrupted a major British art institution.

The activists struck just before noon, supergluing their hands to the frame of the 3-metre-long painting – a reproduction of the Leonardo da Vinci original attributed to his pupil, Giampietrino.
