Lib Dem leader Vince Cable questions UK’s commitment to environmental projects after GIB sale to Australian bank Macquarie

The government is facing renewed criticism after pushing through the “disastrous” sale of the Green Investment Bank (GIB) to the Australian bank Macquarie, as fresh concerns are raised over its commitment to environmental projects.

A consortium led by Macquarie agreed to buy the GIB, which was established in 2012 by the coalition government to fund green infrastructure projects such as windfarms and a waste and bioenergy power plant. The consortium also includes Macquarie’s in-house infrastructure fund and the Universities Superannuation Scheme, a pension fund for British higher education institutions.

Minninglow, Derbyshire The Y Not festival site is still a mess, but a walk along the High Peak Trail underlines the resilience of nature

At the top of Gratton Dale, turning into Mouldridge Lane, the familiar white-walled pasture had been transformed. Diggers and tractors swarmed across the fields, beeping frantically. Grass had been churned up everywhere, and serried ranks of portable loos leaned like wearied soldiers. I was baffled. Was this some sort of war re-enactment?

Then I saw the word TONY spelled out in giant letters in the middle of the busiest field, only the Y was drooping and the N was the wrong way round.

State mines minister rejects two applications at reserves west of Cape Tribulation which campaigners say should set a precedent

The “archaic” practice of mining rivers in north Queensland is making a mockery of Australia’s key policy to protect the Great Barrier Reef, wasting multimillion-dollar efforts to cut runoff pollution, its opponents say.

“Instream” mining in Queensland, the only state still allowing the excavation of rivers for gold, tin and silver, is unleashing torrents of fine sediment in one of the reef’s largest catchments.

Migrating humpback whales avoid loud, nearby sounds. BRAHSS, Author provided

Air guns used for marine oil and gas exploration are loud enough to affect humpback whales up to 3km away, potentially affecting their migration patterns, according to our new research.

Whales’ communication depends on loud sounds, which can travel very efficiently over distances of tens of kilometres in the underwater environment. But our study, published today in the Journal of Experimental Biology, shows that they are affected by other loud ocean noises produced by humans.

As part of the BRAHSS (Behavioural Response of Humpback whales to Seismic Surveys) project, we and our colleagues measured humpback whales’ behavioural responses to air guns like those used in seismic surveys carried out by the offshore mining industry.

Air guns are devices towed behind seismic survey ships that rapidly release compressed air into the ocean, producing a loud bang. The sound travels through the water and into the sea bed, bouncing off various layers of rock, oil or gas. The faint echoes are picked up by sensors towed by the same vessel.

During surveys, the air guns are fired every 10-15 seconds to develop a detailed geological picture of the ocean floor in the area. Although they are not intended to harm whales, there has been concern for many years about the potential impacts of these loud, frequent sounds.

Sound research

Although it sounds like a simple experiment to expose whales to air guns and see what they do, it is logistically difficult. For one thing, the whales may respond to the presence of the ship towing the air guns, rather than the air guns themselves. Another problem is that humpback whales tend to show a lot of natural behavioural variability, making it difficult to tease out the effect of the air gun and ship.

There is also the question of whether any response by the whales is influenced more by the loudness of the air gun, or how close the air blast is to the whale (although obviously the two are linked). Previous studies have assumed that the response is driven primarily by loudness, but we also looked at the effect of proximity.

We used a small air gun and a cluster of guns, towed behind a vessel through the migratory path of more than 120 groups of humpback whales off Queensland’s sunshine coast. By having two different sources, one louder than the other, we were able to fire air blasts of different perceived loudness from the same distance.

We found that whales slowed their migratory speed and deviated around the vessel and the air guns. This response was influenced by a combination of received level and proximity; both were necessary. The whales were affected up to 3km away, at sound levels over 140 decibels, and deviated from their path by about 500 metres. Within this “zone”, whales were more likely to avoid the air guns.

Each tested group moved as one, but our analysis did not include the effects on different group types, such as a female with calf versus a group of adults, for instance.

Our results suggest that when regulating to reduce the impact of loud noise on whale behaviour, we need to take into account not just how loud the noise is, but how far away it is. More research is needed to find out how drastically the whales’ migration routes change as a result of ocean mining noise.

Wayne Lotter had received numerous death threats while battling international ivory-trafficking networks

The head of an animal conservation NGO who had received numerous death threats has been shot and killed by an unknown gunman in Tanzania.

Wayne Lotter, 51, was shot on Wednesday evening in the Masaki district of the city of Dar es Salaam. The wildlife conservationist was being driven from the airport to his hotel when his taxi was stopped by another vehicle. Two men, one armed with a gun opened his car door and shot him.

Supermarkets selling out-of-date produce and apps that identify food at risk of being binned are part of an ambitious plan to slash the nation’s food waste

“They might not taste quite the same,” says Naeeh Ahmed, 37, holding up for inspection a pack of Old El Paso soft tacos. The tower of boxes in front of him are three weeks past their best before date but Ahmed, operations manager at the Best Før supermarket in Oslo, says they’ll stay on display for a good few weeks yet. The same goes for the chocolate biscuits precariously piled up in the display – four weeks past their best before date – and the packs of Tassimo coffee pods that should have been sold in April. But all the prices reflect the product’s age: half-price for the tacos, two-thirds off the biscuits and, at 30 kroner (£3.66) for 32 pods, the coffee is also less than half its regular price.

It would be hard to find cheaper food in Oslo than that sold at Best Før. They flog the stuff that no one else has been able to get rid off. Products whose season has passed, or which have been overproduced, have been arriving at this small store since October last year when the mainstream Lentusgruppen supermarket chain heeded the call of the Norwegian government and decided to take food waste seriously. They established an offshoot in Oslo, the first of its kind in the city, selling the stuff other stores and suppliers throw away. It’s all up front – the shop looks like any other, but a large sign informs customers of the slightly different nature of the food down their aisles and in the chillers, which includes chicken fillets frozen a couple of days before going off.
