No jumping lights, whacking cars or effing and jeffing: the Olympic champion tackles the issues of everyday cyclingLondon’s fleet of Boris bikes are sturdy, convenient even, but hardly famed for their speed and handling. However, if you see one ridden by a tall, bearded man unexpectedly vanish into the horizon when the lights change, don’t be alarmed. It is probably just Sir Bradley Wiggins getting about town.The 35-year-old will retire from top-level competition after the Rio Olympics, so his mind is turning to such everyday riding, and Wiggins predicts London will become as packed with bikes as the Netherlands.

The last time the Earth saw such a sustained increase was over 11 millennia ago, says US science agency. Climate Home reportsAtmospheric concentrations of carbon dioxide last year rose by the biggest margin since records began, according to a US federal science agency.Fossil fuel burning and a strong El Niño weather pattern pushed CO2 levels 3.05 parts per million (ppm) on a year earlier to 402.6 ppm, as measured at the Mauna Loa Observatory in Hawaii, the National Oceanic and Atmospheric Administration (Noaa) said on Wednesday.

Beer made from old bread; chutney from windfalls; shops that sell excess stock at cut prices – there are many ways to tackle the scourge of squandered foodIf they think about it at all, most people think of food waste, or surplus, as the “reduced to clear” section in the supermarket. But that is just a tiny fraction of what exists. The truth is that most food surpluses in the supply chain never even reach our supermarket shelves.Let me take you back to the Queen’s diamond jubilee in 2012. What a glorious weekend we were planning – barbecues, street parties and garden games, while we watched the 1,000-strong flotilla cruise down the Thames. Retailers had been planning for months, ensuring that their manufacturers and suppliers had a bumper supply of burgers, sausages, Pimms, cucumber and fruit ready to meet demand. Continue reading...

High ocean temperatures helped cause toxic bloom that has wiped out up to 20% of Chile’s total production for the yearA deadly algal bloom has hit the world’s second biggest salmon exporter, Chile, where nearly 23 million fish have already died and the economic impact from lost production has soared to $800m (£565m), industry and government sources told Reuters.The dead fish could easily fill 14 Olympic-sized swimming pools, said Jose Miguel Burgos, the head of the government’s Sernapesca fisheries body.

More than 20,000 people are expected to turn out for four days of wrangling, milking and even eating. But opposition from animal welfare groups is mountingIf you are thrilled by the idea of gawping at a giant vat of writhing rattlesnakes, taking part in a rattlesnake-eating competition or witnessing a beauty queen decapitate a rattlesnake, then west Texas is the place to be this weekend.The world’s largest rattlesnake “roundup” kicks off in the remote town of Sweetwater on Thursday. The four-day event attracted 20,000 paying spectators – double the town’s population – last year, with a bumper haul of snakes set to draw large numbers again this time around. Continue reading...

Overgrazing and a cycle of summer drought and winter snow has degraded vital pastureland in Mongolia, killing livestock and jeopardising livelihoodsDaashka and his brother tear across the Mongolian steppe on a motorbike in a desperate search for somewhere to graze their herds. Pastureland is dwindling rapidly as the country is beset by a cycle of drought and harsh winter that is killing off livestock in droves.“The summer ends early now and the fall is short and dry. Then there’s the long winter,” said Daashka, a 19-year-old herder who uses just one name and lives in the central Ulziit region. Continue reading...

Baltic Sea proposal would allow catches well above current sustainable levels needed to restore healthy fish stocks, putting some species at risk, conservationists warnFishermen could soon be given carte blanche to overfish without needing to worry about restoring fish populations to a healthy state under a leaked European commission proposal seen by the Guardian.If it is approved, the blueprint for the Baltic Sea could soon be applied to the North Sea too, potentially threatening the future of some cod species, MEPs say.

It began with Fairtrade. Almost 30 years later, with hundreds of different certifications is it time to question what they all do and who benefits?In 1988, the first Fairtrade label, Max Havelaar, was applied to packs of Mexican coffee sold in Dutch supermarkets. At the time, using a product label to say something about standards in a supply chain was revolutionary, but today it is routine. The Ecolabel Index currently lists 463 certifications in 199 countries.On the face of it, certifications on everything from fish to timber can be seen as progress, promising higher standards and transparency in the pursuit of sustainability. But what purpose are the certification labels actually serving? Can we assume that they are beneficial to producers? Do consumers understand what’s behind a certification label, and does it even matter if they do? These were some of the questions asked at a recent roundtable discussion hosted by the Guardian and supported by Mondelēz International. Continue reading...

Sandy, Bedfordshire My focus was on the stylised gestures that would have been clearly read by the bird on the next branchA fevered burst of birdsong drew more than one pair of eyes to the branch of a hedgerow tree. Fraught with seasonal urgency, the robin’s song was a liquid stream; not a gentle brook, but a gushing beck, some notes thrown high and uncontrollably as if dashed against a rock, others pitched down a waterfall, and all poured out in a tumbling, erratic, attention-seeking rush.There was a pause. Another robin worked its way down the hedge towards it, then alighted on a near parallel perch about a metre away. The first bird threw out its chest, arched its back so that its head all but touched its shoulders and began to rear up and down in poised sweeps, a series of movements that – in human terms – would not look out of place on a yoga mat. Continue reading...

If allowed to go forward, plaintiffs in Oregon will ask court to hold government responsible for violating their rights to life, liberty, property and equal protectionTwenty-one teenagers appeared in an Oregon courtroom to challenge the federal government over what they claim is a failure to protect them from the impacts of climate change, while several hundred schoolchildren protested outside.While the mass of children, their parents, chaperones and local activists lined up in the rain on Wednesday, trying to get in to watch the proceedings, Judge Thomas Coffin of the US district court in Eugene, Oregon, questioned the lawyers on the government’s claim that the case should be thrown out.

The government claims the seal-fur industry is lucrative, but protesters argue it costs more to monitor the practice than the hunts generate in revenueJustin Trudeau’s government has come under renewed pressure to ban seal hunting after it emerged that Canada is spending far more on monitoring seal hunts than it receives in the export value of seal products.

Charity Commission advice to steer clear is misguided and will lead to an EU debate conducted only by business leaders and politiciansEarlier this week the Charity Commission warned, in new guidance, that charities should only enter the EU referendum debate in exceptional circumstances, and those that do will be closely watched by the regulator. It is clearly intending to deter charities from getting involved – which, in my opinion, will be detrimental to the debate.This European referendum is arguably the single most important decision of a generation and the ramifications are too great to be allowed to be dominated by private sector and party political voices alone. The new guidance is also at odds with what the prime minister said in Davos on 21 January: “that business, NGOs and other organisations won’t hold back” in campaigning to stay in the EU.

For investors who seek long-term low-risk investments, the 20 year lifespan of an onshore wind farm is an attractive prospectFour years ago, Danish wind turbine manufacturer Vestas was on the brink of bankruptcy. The company famous for sending in the bailiffs to evict employees occupying their Isle of Wight site, axed more than 3,700 jobs. Relations were in turmoil as the chair, deputy chair, chief financial officer and deputy chief executive left in quick succession. The CEO himself followed one year later as net losses escalated sevenfold to £53m.Fast forward to 2016 and the world’s biggest turbine manufacturer is reporting historic successes, including a record €685m (£530m) net profit last year and a 22% increase on revenue to €8.4bn (£6.5bn). It also recently announced it had been awarded a contract to supply turbines for Europe’s largest ever onshore wind project in Norway. Continue reading...

As the Paris climate deal requires developing countries to monitor their emissions, organisations are using online courses to train a new breed of green accountants capable of the complex task, reports Environment 360Michael Gillenwater is so tired he is mixing up his words, worn out from weeks of conference calls with the United Nations, the German government, and more. “I’m exhausted,” he says. In the wake of the Paris climate agreement last December, everyone wants advice from the Greenhouse Gas Management Institute (GHGMI) – Gillenwater’s non-profit organization based in Washington, DC – on how to step up the developing world’s capacity for counting carbon.The institute offers online courses in greenhouse gas monitoring to practitioners around the globe, and since the Paris agreement was reached, business has been brisk. “We’re excited,” he says. “There’s a window here to make something permanent happen.” Continue reading...

The wetlands are this Indian city’s free sewage works, a fertile aquatic garden and, most importantly, a flood defence – but they’re under threat from developers. One environmentalist is leading the resistanceThe trees on the streets of Kolkata in January are dusty, like neglected pot plants. At traffic lights, salesmen offer feather dusters for drivers to wipe their grimy cars. Shrubs are planted on the central reservation of the city’s new flyovers, surrounded by the implausible boasts on signs proclaiming a “clean and green” city. But the most frequently recurring poster, above almost every street corner, appeals for investors to “Come to Bengal – Ride the Growth”.Kolkata, a famously cultured city of 14.5 million people – once the second city of the British empire after London – is keen to catch up with Delhi, Mumbai, Chennai and Bangalore, the dynamic and rapidly modernising megacities of the fastest growing major economy in the world.

Wenlock Edge An ancient oak shows signs of awakening after another winterThe oak loomed above other trees in a scrubby corner of the field. Despite claims that it was officially spring, and with no respect for meteorology, calendars or tradition, the great oak seemed to feel as though it was holding on to winter and would not turn until it was good and ready.It must have been an important landmark for centuries, visible from all cardinal points, growing on flat pasture close to a spring that issues from the hillside and pours into a wooded ravine to join the brook, which then enters the river Severn. A boundary marker, a meeting place, a preaching tree, a tree for wakes and waits, fairs and festivals, a gallows? Continue reading...
