Houston has experienced an unexpected side-effect of the floods that have hit the Texan city – floating islands made up of thousands of venomous fire ants. The naturally aggressive ants are able to survive the rising water by forming rafts with their own bodies, and can survive for weeks before breaking up

Flood waters were still pouring into homes in Houston – bringing with them a further threat to public health

Tony Abbott fires opening salvo in looming party debate over clean energy, insisting PM must ‘go ahead with new coal-fired power’ because he backs hydroTony Abbott has thrown down the gauntlet to Malcolm Turnbull in the lead-up to the Coalition’s renewed deliberations over the Finkel review, declaring if the prime minister is prepared to back pumped hydro, he also needs to support a new coal-fired power station.

Myron Ebell, who headed the EPA’s transition team when Trump became president, said the last decade has been a period of ‘low hurricane activity’Conservative groups with close links to the Trump administration have sought to ridicule the link between climate change and events such as tropical storm Harvey, amid warnings from scientists that storms are being exacerbated by warming temperatures.Harvey, which smashed into the Texas coast on Friday, rapidly developed into a Category 4 hurricane and has drenched parts of Houston with around 50in of rain in less than a week, more than the city typically receives in a year. So much rain fell that the National Weather Service had to add new colours to its maps. Continue reading...

After meeting with energy chiefs, Malcolm Turnbull says the Coalition will not set a clean energy target to exclude coalMalcolm Turnbull has signalled the government’s eventual response to the Finkel review will not create any barriers to building new coal-fired power stations, as he secured additional undertakings from energy retailers to be more transparent with customers.

From self-healing phone screens to concrete that repairs itself, businesses are investing in futuristic materials. But can it curb our throwaway habits?Smashed screens, broken circuits, water damaged keyboards – we send millions of tonnes of broken electronics to the dump every year. But what if our phones and laptops could fix themselves?This month, it emerged that smartphone company Motorola had filed a patent for a self-healing phone display. The design includes a “shape memory polymer”, which the patent application says would at least partly reverse damage when exposed to heat. In theory, at least, users could hit a “repair” button and wait for their cracked screens to mend. Continue reading...

St Dennis, Cornwall From the moss-coated fort, spoil heaps dominate the view but close by sits the waste energy plant and a bog has become a nature reserveFrom the ancient vantage point of Carne Hill, china-clay works dominate the landscape with vegetated spoil heaps, older conical tips and the whiteness of an open-cast pit at Fraddon.The curved roofs and twin stacks of the Cornwall Energy Recovery Centre are close by, and lower down, to the north, rows of pylons slung with cables stretch along the flat expanse of Goss Moor towards the electricity substation.

‘Last-chance tourism’ spurs on other visitors but there has been lull in bookings after coral bleaching, senators toldOverseas tourists have begun to doubt the value of a trip to the ailing Great Barrier Reef and it is getting increasingly difficult to “show people what they expect to see”, a dive operator has told a federal Senate inquiry.A Port Douglas operator, John Edmondson, said “last-chance tourism” was spurring on other visitors but there had been a “weird” lull in bookings this year after back-to-back mass bleaching events made dead coral an unavoidable sight on reef visits.

Canada has a hand in the misery Haitians are fleeing. Asylum should serve as reparationsThe minders of Canadian PM Justin Trudeau’s brand are surely displeased. He’s spent two years cultivating an image of Canada’s refugee system as the political equivalent of airport hugs and teddy-bears. And now the pressure is on him to act like that were remotely the truth.The image of the country as a welcome haven was pitched to win the support of millions of people in Canada who rightly feel two things: compassion for the plight of refugees and disgust for the antics of Donald Trump. But refugee rights advocates had warned what would come to pass: desperate people would take Trudeau at his word. Continue reading...

Target will transfer pressure to other sectors of the economy to reduce their emissions, research showsThe clean energy target recommended by Australia’s chief scientist, Alan Finkel, won’t deliver Australia’s obligations under the Paris agreement and will only transfer pressure to other sectors of the economy to reduce their emissions, according to new analysis.The new research comes as the Coalition’s difficult internal deliberations over the Finkel review are set to resume, with a report due from the Australian Energy Market Operator about the dispatchable power requirements of the electricity grid after the closure of two ageing coal-fired power stations.

Houston has some of the most lax building regulations in potential flood zones – and the president wants to spread that policy across the US• Tropical storm Harvey – live updatesAfter all the furore, it’s hard to remember now that Donald Trump’s combative press conference earlier this month was supposed to be about infrastructure. Holding two flowcharts, the president explained how his latest executive orders would slash the time it takes to get new buildings improved and that the permitting process would “go very, very quickly”.Related: Trump's infrastructure plan: let's have another look at those really long charts Continue reading...

A study finds that accelerated growing conditions on some fish farms are causing hearing impairments in salmon. It’s a reminder that aquaculture’s own accelerated rise needs to be closely managedTo grasp the wide-ranging impacts of our industrial food systems, take a peek inside a salmon’s ear. That’s what marine biologist Tormey Reimer did when, in 2013 at the University of Melbourne, she began to investigate deformities that were developing on the structures that salmon use to hear.Bony fish species have structures called otoliths in their ears, small crystals that they use to detect sound. Biologists have for decades relied on otoliths to age fish, using them like rings on a tree. But what Reimer saw was an altogether larger, lighter, and more transparent crystal called a vaterite, growing into the otolith and obstructing the fish’s ability to hear. “I did a bit of digging and found it was much more common in farmed salmon than wild,” she says. And, she began to suspect it had something to do with the accelerated growth rates in fish farms. Continue reading...

This year, China’s government enacted a ban on ivory sales and started closing down carving workshops, despite ivory carving being seen as an ‘intangible cultural heritage’. How did such an astonishing U-turn come about?For years Chinese government officials were followed around the world, at every meeting, by a single issue: the scores of dead elephants across Africa, and the international community that blamed China for this “ivory “holocaust”.

The anti-cycling backlash in the media in the aftermath of Charlie Alliston trial suggests roads and streets overrun by dangerous cyclists, but is this true?

Claxton, Norfolk Lined up on the telephone wires, they stretch, preen and snooze, riding the tide swell of airThe view from my office includes a junction box where five telephone wires converge at the top of a pole. For several years, it has been a favourite gathering place for the season’s young swallows and they wreathe this banal technology in the joyous rhythms of their movements and sounds.The immatures are separable by pale fringes to their wing feathers, but also by the downturned yellow gape-lines at the corners of their mouths, which give them a wonderfully comic clown-like glumness. It is as if all the swirl of these late-August days – the balletic fly-snatching, the sun-blessed leisure, the quiet feather care as they sit amid a pool of the adult swallows’ desultory song – were a source of strange ennui.

La Trobe University Bendigo student Kirra Coventry filmed her group of outdoor and environmental education classmates helping a koala that had become stranded by rapidly rising water in the Murray river. The students were learning to be river guides when they saw the koala on the edge of Ulupna Island. The students told associate lecturer Chris Townsend it was low in a tree and seemed to be trying to find dry land. They pushed an empty canoe out to it and it climbed aboard, took a seat, then disembarked once it reached shore, where it had a lengthy drink. Townsend said koalas, which are considered a vulnerable species in parts of Australia, were relocated to river islands like Ulupna in the late 1980s and there was now a healthy population there. ‘Koalas are very, very fussy about the trees they will feed in and live in,’ he said. ‘Obviously leading up to this it had found the perfect tree, but I think the floodwaters came up a little bit quickly and it didn’t have time to get down’ Continue reading...

Captain Paul Watson accuses ‘hostile governments’ in the US, Australia and New Zealand of being in league with TokyoThe anti-whaling organisation Sea Shepherd will not contest the Southern Ocean against Japanese whalers this season, Captain Paul Watson has announced, accusing “hostile governments” in the US, Australia and New Zealand of acting “in league with Japan” against the protest vessel.Sea Shepherd has been obstructing Japanese whaling vessels in the Southern Ocean each year since 2005, but Watson said the cost of sending vessels south, Japan’s increased use of military technology to track them, and new anti-terrorism laws passed specifically to thwart Sea Shepherd’s activities made physically tracking the ships impossible.

Wothorpe-on-the-Hill, Cambridgeshire The air is awash with noise, a roar that wavers only slightly, and never below uncomfortableThe road climbs and thins with each turn. Where it reaches a little fist of cottages it doesn’t stop but instead, strangely, has its way blocked from waist height up by low branches. A dead road, leading to the old reservoir. I walk a footpath bordered by stone walls, then over a stile and here it is, a sweep of miniature country. A rumpled slope, trees fat with summer, a little pond catching the sky. August dew sits on everything, and early sun lights every drop to a shimmer. I see rabbits, molehills, every bush twitching with life.I live less than a mile from here and would come to this meadow more, but for one thing. The air is awash with it, a roar that wavers only slightly, and never below uncomfortable. It’s rush hour now, so maybe this is as bad as it gets. But it never goes away. Continue reading...

Originally published in the Manchester Guardian on 31 August 1917When the heavy showers had passed, the sun burst out from behind drifting clouds, and studded the dripping hedges with diamonds. For ten yards or more privet, in full flower broke the monotony of thorn and bramble, and here fifteen or twenty red admiral butterflies fanned their gorgeous wings as they sipped the sweets. The air was heavy with the scent of privet. Golden–rod, a blaze beneath the hedge, attracted other red admirals, and amongst them were small tortoiseshells and a few peacocks. True to its name, the wall butterfly was more plentiful where rugged stone walls replaced the hedgerows, but it abounded alike in all the lanes and on the rocky outcrops, covered with ragwort, scabious, and eyebright, which are so noticeable a feature of North Wales.Privet, by the way, is troubling one of my correspondents. He finds his hedge attacked by small white grubs, which shelter in the curled and shrivelled leaves. I do not find my privets badly damaged, though a few shoots have been attacked. It is the caterpillar of one of the small leaf-mining moths, for the grubs in their earlier stages, at any rate, feed within the two layers of leaf-skin. I can only advise that he cuts off the damaged shoots and burns them so as to diminish the numbers of the moths. Continue reading...

The highest mountain in the British Isles is currently without snow – and researchers believe permanent white mountain tops could soon be a thing of the pastAin’t no mountain dry enough? Ben Nevis may well have grown by a metre last year but now it is also nude from basecamp up for the first time in 11 years.You would expect snow under foot atop the summit’s stone cairn at the lofty height of 1,345m, not a blunt, barren crown. So what on earth happened to the formerly covered peak? Continue reading...
