Sadiq Khan should take heed of the evidence and push on with the changes needed to keep cyclists safe on London’s roadsThe decay of London’s cycling programme is starting to cost lives. In the last three and a half weeks, three cyclists have been killed at locations where schemes to make the road safe, or provide a safe alternative route, have been watered down or stopped under the mayoralty of Sadiq Khan.On 11 May, Oliver Speke died after a collision two days earlier with a lorry at Romney Road, Greenwich. On 18 May, Edgaras Cepura was killed by a lorry on the same road, a mile or so to the east. There was supposed to have been a new cycle superhighway avoiding Romney Road by now, and a safe, segregated junction at the roundabout where Cepura was killed. Both schemes were postponed indefinitely after Khan came to office. Continue reading...

We urgently need consumers, business and governments to cut consumption of single-use, throwaway plastics, writes the UN Environment chiefPlastic pollution has grabbed the world’s attention, and with good cause.More than 100 years after its invention, we’re addicted. To pass a day without encountering some form of plastic is nearly impossible. We’ve always been eager to embrace the promise of a product that could make life cheaper, faster, easier. Now, after a century of unchecked production and consumption, convenience has turned to crisis. Continue reading...

Garron Point, Aberdeenshire: The wailing of the birds created a wraparound atmosphere of such density and chaos that I was almost unbalanced by itBeyond Sandend village and the slow white waves running into its sunlit bay, there was this wilderness of guano-nourished grass and three northward-facing ribs of metamorphosed sedimentary rock. The latter were tilted on end and weathered along their joints, and the gulls on the raised slabs of ancient stone were spaced in heraldic assembly.Through the luxuriant hummocks by the cliff edge I manoeuvred with caution that was more than just fear of falling. The wailing of the birds created a wraparound atmosphere of such density and chaos that I was almost unbalanced by it. Continue reading...

$1bn project in Queensland’s Bowen basin to consist of almost 200 turbinesThe Queensland government has approved the country’s largest windfarm, a $1bn project to build almost 200 turbines in the shadow of the Bowen basin’s coalmines.The 800-megawatt Clarke Creek project, in cattle country north-west of Rockhampton, received planning approval on Tuesday morning.

Advances in clean energy expected to cause a sudden drop in demand for fossil fuels, leaving companies with trillions in stranded assetsPlunging prices for renewable energy and rapidly increasing investment in low-carbon technologies could leave fossil fuel companies with trillions in stranded assets and spark a global financial crisis, a new study has found.A sudden drop in demand for fossil fuels before 2035 is likely, according to the study, given the current global investments and economic advantages in a low-carbon transition.

As the world moves towards a low-carbon economy, fossil fuel investments worth trillions of dollars, from oil wells to cars, will lose their valueRead more: ‘Carbon bubble’ could spark global financial crisis, study warnsInvestments amounting to trillions of dollars in fossil fuels – coal mines, oil wells, power stations, conventional vehicles – will lose their value when the world moves decisively to a low-carbon economy. Fossil fuel reserves and production facilities will become stranded assets, having absorbed capital but unable to be used to make a profit. This carbon bubble has been estimated at between $1tn and $4tn (£3tn), a large chunk of the global economy’s balance sheet. Continue reading...

4 June 1918 Most of these foliage-devourers are the larvae of geometer moths of various kinds, sometimes called loopersCaterpillars are doing their best to eat up the woods. On some of the sycamores, elms, and other trees the leaves are already reduced to lacework; on others, oaks in particular, many of the leaves have vanished. Most of these foliage-devourers are the larvae of geometer moths of various kinds; they are sometimes called loopers, on account of their habit of humping up their backs and straightening themselves out for the next reach, as they walk, or they are known as stick caterpillars when, at rest, they apparently pretend to be lifeless twigs. Others are smaller moths, leaf-rollers and miners, and others, again, particularly abundant on the hawthorns but by no means confining their attention to this plant, are the showy little hairy “palmer worms,” the caterpillars of the gold-tailed moth, whose irritating hairs give tender skins a rash.Related: Health warning as toxic hairy caterpillars take over woodlands Continue reading...

Great Ridge, Peak District: Momentum builds like a wave, and in a thrilling, spine-shivering moment, a glittering ribbon sparkles into being along the ridgeI reach the top of Mam Tor, out of breath, as the sun is dropping behind the bulk of Kinder Scout and dying in a great flare of scattered orange.It is quarter past nine on a Tuesday night, but the top of the peak is a throng of activity; dozens of people are milling around the summit and marvelling at the sunset, unfazed by a biting wind. I squint into the east, and can faintly make out the dots of hundreds more people trailing into the distance. Continue reading...

Warning about conflicts, wars and mass migration is the wrong way to approach thingsThe Australian Senate’s declaration last month that climate change is a “current and existential national security risk” was clearly intended to inject much-needed urgency into the country’s climate policy stalemate. Bringing together the unusual bedfellows of military generals and environmentalists to warn about the dangers of climate change, it has the possibility to break though Australia’s culture wars on the issue. However, by framing climate change as a security matter, it also has significant consequences in shaping how we respond to a warming planet. As the climate crisis unfolds, is the military the institution we want to turn to for solutions?

City has cleared 8,414 trees in last three years – twice as many as any other authorityNewcastle has become the tree-felling capital of the UK after the council chopped down almost twice as many trees as any other local authority.More than 110,000 trees have been cut down by councils across the UK in the last three years, according to figures gathered under the Freedom of Information (FOI) act by the Sunday Times. Some 8,414 were in Newcastle, more than in any other rural or urban local authority. Wiltshire was next, having felled 4,778 in the same period, followed by Edinburgh with 4,435. Continue reading...

Guy Smith says it’s unfair to point the finger at farming as the cause of environmental damage, Iain Climie addresses food wastage and Dr Blake Alcott says the most effective way to reduce your carbon footprint is to not reproduceOne fundamental point has been overlooked by Kevin Rushby in his article about the plight of the countryside due to agriculture (The killing fields, G2, 31 May). There has been no intensification of agriculture in the UK for 25 years.Government statistics show pesticide and fertiliser use has been significantly reduced. There are fewer crops grown and the numbers of pigs, sheep and cattle have fallen. So to point the finger at farming as the cause of environmental degradation through intensification makes no sense, especially when you consider the other changes that have taken place in that time – increased housebuilding, more roads, and more cars on those roads – and the impact they have had on the country’s landscape.

With 32 million visitors expected this year, fears grow that the country cannot copeGreece is braced for another bumper year. The tourists will not stop coming. For every one of its citizens, three foreign visitors – 32 million in total – will arrive this year, more than at any other time since records began.It’s an extraordinary feat for a country that has battled with bankruptcy, at times has been better known for its protests and riots and, only three years ago, narrowly escaped euro ejection. Tourism is the heavy industry that has helped keep catastrophe at bay. Continue reading...

Sustainability is intrinsic and not an afterthought for many designers taking part in this year’s eventThe future of fashion is sustainable if graduate fashion week is anything to go by. The annual four-day event event at London’s Old Truman Brewery comprises installations, catwalk shows and two prize-giving ceremonies and promises to uncover the torchbearers of “considered design”, according to the event’s creative and managing director, Martyn Roberts.Roberts believes that graduates can help existing fashion houses and retailers tap into “what a new generation of consumers want”. As brands from every echelon seek to improve their social, economic and environmental impact, graduate fashion week, says Roberts, is where many companies are looking for creatives for whom sustainability is intrinsic, as opposed to an afterthought, to show them how it’s done.

When a tsunami hit the nuclear plant, thousands fled. Many never returned – but has the radiation risk been exaggerated?Shunichi Yamashita knows a lot of about the health effects of radiation. But he is a pariah in his home country of Japan, because he insists on telling those evacuated after the 2011 Fukushima nuclear accident that the hazards are much less than they suppose. Could he be right?Yamashita was born in Nagasaki in 1952, seven years after the world’s second atomic weapon obliterated much of the city. “My mother was 16 years old when the bomb dropped and she was two miles away,” he told me at his office in the city, where he still lives with his mother, who is now 88.

Start Point, Devon: Spider crabs rub pieces of seaweed against the backs of their shells until they stick, creating remarkable camouflageThe combe above the beach echoes with the calls of chiffchaffs, and cock stonechats flick and churr on the wind-stunted hawthorns that line the footpath. Around the twin radio masts – a 20th-century riposte to Start Point’s whitewashed gothic lighthouse – a small flock of swallows cut and swerve.Beneath the sea there are signs of spring too. Common spider crabs (Maja brachydactyla), which have been overwintering in the depths, start to appear close to shore, a sight that has become a feature of my first sea swims of the year.

It’s not perfect, but the city has ambitious plans for cycling, and the Festival of Cycling offers a chance to celebrate progressIn theory, Edinburgh might not look like the perfect city for cycling. Apart from the weather there are the (in)famous hills, then there’s the … (add your own excuses here.) But things are changing.Currently the city council is committing 10% of its transport budget to cycling, a first for a UK city, as well as introducing 20mph speed limits across a large area. And in September, Edinburgh will finally be getting its own bikeshare scheme, which will include a proportion of e-bikes to help beat the hills.
