Giant Antarctic ice shelf breaks into the sea

A vast hunk of floating ice has broken away from the Antarctic peninsula, threatening the collapse of a much larger ice shelf behind it, in a development that has shocked climate scientists.
Satellite images show that about 160 square miles of the Wilkins ice shelf has been lost since the end of February, leaving the ice interior now "hanging by a thread".
The collapsing shelf suggests that climate change could be forcing change much more quickly than scientists had predicted.
"The ice shelf is hanging by a thread," said Professor David Vaughan of the British Antarctic Survey (BAS). "We'll know in the next few days or weeks what its fate will be."
The Wilkins shelf covers an area of 5,600 square miles (14,500 sq km). It is now protected by just a thin thread of ice between two islands.
Vaughan was a member of the team that predicted in 1993 that global warming could cause the Wilkins shelf to collapse within 30 years.
The shedding of peripheral floating ice shelves has occurred elsewhere on the peninsula, allowing inland ice to move towards the sea and cause rising sea levels.
Some areas of the frozen continent have been cooler in recent years, and have added ice through accumulated snowfall. This year, the thin floating layer of sea ice that forms each austral winter and fades in summer has in fact been larger than usual, in contrast to the Arctic.
But in other parts — such as the West Antarctic ice sheet — ice is being lost to the sea.
The darker area shows the chunk that has broken away. Picture: Nasa Climate scientists around Antarctica were taken by surprise by the new find. "Wilkins is the largest ice shelf on the Antarctic peninsula yet to be threatened," Vaughan said.
"I didn't expect to see things happen this quickly. We predicted it would happen, but it's happened twice as fast as we predicted."
The retreat of the shelf was first spotted from satellite data by Ted Scambos, a glaciologist at the University of Colorado.
He alerted the BAS, which sent an aircraft to assess the extent of the damage.
Jim Elliott, who filmed part of the breakup, said: "It was awesome. We flew along the main crack and observed the sheer scale of movement from the breakage. Big chunks of ice, the size of small houses, look as though they've been thrown around like rubble — it's like an explosion."
The Antarctic peninsula, which stretches north from the frozen continent towards South America, has experienced unprecedented warming over the past 50 years.
Six other ice shelves have already been lost entirely — the Prince Gustav Channel, Larsen Inlet, Larsen B, Wordie, Muller and Jones shelves.
But the Wilkins shelf is farther south than other ice that has retreated, so should be better protected by colder temperatures.
Vaughan said: "It's bigger than any ice shelf we've seen retreating before, and in the long term it could be a taste of other things to come. It is another indication of the impact that climate change is having on the region."

Going green on the festival scene

Cars and rubbish can make a festival an eco-disaster. But now organisers are tackling their carbon footprint.

Thom Yorke's statement at a press conference for Friends of the Earth last week that Radiohead won't be playing Glastonbury this year, because it lacks "a public transport infrastructure", has brought home an uncomfortable truth. The churned, litter-embedded wasteland left behind the day after a typical rock festival already looks like a Friends of the Earth recruiting poster. But as the summer festival season grows more packed and varied, Yorke has identified a sea-change. Travellers to the glorious West Country, where Glastonbury is one of many festivals this year, are getting used to the fact that their trip is environmentally damaging. Traditional rock fans at Reading and Leeds, meanwhile, are being encouraged to return their beer-cups for recycling, preferably before urinating in them to hurl at Funeral for a Friend.

Most festivals claim to be taking some sort of "green" stand this year. Glastonbury's Michael Eavis, though, doesn't need Yorke to see a starker choice. "The environmental impact of festivals is disastrous," he states bluntly. "To pretend they're green is ridiculous. You can recycle like mad, you can bring people on public transport, which we do. Overall, though, with generator-diesel and travel, the greenest thing to do is not to run the event. But if we want something like Glastonbury, if it's part of our culture, that's the price one has to pay. The spiritual high that people get across the nation, and the moral integrity of the crowd, outweighs the environmental impact. We've always minimised the damage. But if you switched off everything that created carbon, we'd be bored to tears."

Smaller, newer festivals have nevertheless done their best. "We started wanting to make as little carbon impact as possible," recalls Graeme Merrifield, organiser of Wychwood, now in its fourth year at Cheltenham Racecourse. "Festivals who call themselves green actually go to a greenfield site in the middle of nowhere. They have to bring infrastructure in, and there's no public transport – cars are easily festivals' biggest environmental cost. We have a very strong alliance with Friends of the Earth, to build sustainable plans. We're creating a small community of like-minded people. We have workshops about green issues; ideas people can put in their lives if they want. But being carbon-neutral is fanciful."

Chris Tarren, production manager for both Wychwood and Dorset's End of the Road festival, has detailed green policies for both: low-energy light-bulbs, lessening the power pumped by generators; daylight sensors on lighting; over 60 per cent of waste recycled on-site. Wychwood has a solar cinema. End of the Road's food is locally (where possible) and ethically sourced, with biodegradable cutlery. Its co-creator Sofia Hagberg, coming from Sweden's micro-recycling culture, ensures even cigarette butts are sifted out. "I believe every little thing counts," she says. "I was surprised at how well the site looked at the end. People take responsibility when they see we care."

"You can try to have a carbon-neutral festival," believes the Isle of Wight's John Giddings. "With wind turbines and waves, you've got things at your disposal that you don't get in downtown Fulham. There are going to be elements of wind-power in the festival. We're also negotiating to plant 50,000 trees, one for every festival-goer. We're just wondering where to fit them on the island...."

The latter policy sounds like a benign gesture that hasn't quite been thought through, something that exercises Tarren. "There's a serious lack of understanding," he says. "Everyone thinks it's all about this buzz-word the Government keeps coming out with, cutting your 'carbon footprint'. But people don't understand what that means, or how individual efforts might make a difference. Why are we promoting the fact that we're going to be as green as possible, when we're still creating carbon? If the Government helped with costs, instead of buzz-words... I'd love to use green generators. But the green tax puts fuel costs up 80 per cent."

The attractions of the smaller festivals, though – their human, approachable scale, and personal, not corporate priorities – are having wider benefits, as Andrew Haworth, the major promoter and Live Nation's new environmental officer, explains. "Smaller festivals are incredibly useful for trailing initiatives that we can then scale up and try on a much larger scale. I could, theoretically, ensure solar panels [were in place] all over Hyde Park for our Wireless festival. But if the weather's not right those four days, we have no power. We can't take those risks. It's also easier if festivals start from scratch. If you're trying to take a big established festival in a direction it hasn't followed previously, you have to take baby steps. You can't outrun audience expectations. But it makes moral and business sense to harness live music's energy at putting over what's possible – to reduce our environmental footprint."

Hearing Melvin Benn, who as managing director of Festival Nation promotes Reading, Leeds, Glastonbury, Download and Latitude, earnestly discuss a new form of recyclable wax paper for Reading's beer cups, shows how things are changing. Suffolk's Latitude is his eco-flagship for older, family audiences, and even the bars serving its local cider are made from sustainable timber. But where Latitude's patrons have reusable beer-cups worth £2, this would, he says, get them "nicked or thrown" at Reading or Leeds, where returning one nets you 10p. More than 90 per cent recycling was the result. Two bags of recyclable rubbish got you a beer.

As Benn accepts, responsible behaviour at rock festivals is a contradiction. "Teenagers are teenagers. My 18-year-old's environmentally conscious, but can I get him to turn the light off? Work within what the audience actually are, rather than pretend they'll automatically change. They need an endgame – a can of beer. Not just the promise that they'll feel good. On the other hand, I have 70,000 young people camping at Reading. Not one has a TV, record-player, hair-drier or lights. At home, they'd be burning electricity. At festivals, their carbon footprint is near-zero. And they're seeing 30 to 50 bands at one go."

"They're all changing as fast as they can," pressure group A Greener Festival's Ben Challis admits. "The guy who used to run Download was quite brutal about it. He got a £250,000 landfill bill, went green, then worked out that some people might want a green festival, and he could make money. Then he felt a warm glow. Now, it's up to the audiences to do more. Driving to a festival without thinking about lift-share now starts to feel irresponsible. What Thom Yorke is doing is great, but he's not quite right; the real carbon footprint is from the audience, not the band."

This remains the elephant in the room for fans. Glastonbury has always been green at heart. Reading, often indifferent but in walking distance from a train station, is greener. But, though there are beautiful city festivals such as Leicester's Summer Sundae, the point of most is to experience strange music in an inaccessible, probably West-Country setting far from normal life. End of the Road, for all its shuttle-buses and lift-shares, is aptly named. But, like Glastonbury, its heart-stopping beauty is worth more, I would contend, than the carbon-benefits of central London.

"Can it be justified?" Hagberg agonises. "Depends who you're asking. Mother Earth, probably not. The people who leave full of positive memories, in a more idealistic frame of mind? Maybe so."

Offsetting code confirmed

Wednesday 20 February 2008

The Government has urged the carbon offsetting industry to aim for higher standards, as it launched the new Code of Best Practice on the subject this week. The code, which is to be backed by a quality mark, will be initially based on schemes using Kyoto-compliant credits. The aim of the programme is to create a transparency for consumers in order to introduce confidence in the market.“I think it’s right that we set a high standard. It’s important that consumers who want to buy carbon offsets with confidence can do just that. When a customer buys a tonne of carbon with the Government’s quality mark, they’ll know they’re buying a full tonne of carbon,” said Environment Secretary Hilary Benn. “However, we recognise that credits from the unregulated market may be innovative and of a very high standard. So we’re leaving the Offsetting Code open to high-quality voluntary offsetting products, provided the industry can provide a similar level of assurance about the standard of the credits. The challenge to the offsetting industry is clear: to establish a clear, rigorous standard for voluntary projects that deals with the concerns that have been raised. We will support them in developing that standard – and when we have the necessary guarantees, we’ll include high-quality voluntary offsets in the Code.”Green group Friends of the Earth sounded a warning over the Government’s offsetting accreditation, on the basis that it could provide encouragement for people to continue emission-heavy practices with a clear conscience, doing nothing to promote genuinely greener living.“Carbon offsetting cannot substitute cutting emissions here and now,” said FoE’s Energy Campaigner Mary Taylor. “This code will still allow offsets to be sold for our increasingly polluting lifestyles – such as sports utility vehicles and flying on extra weekend holidays.”

Livingstone announces major cycling scheme

By Jeremy Lovell Reuters - Monday, February 11 05:13 pm

LONDON (Reuters) - London will adopt a bicycle hire scheme similar to a popular initiative in Paris under a $1 billion (513 million pound) cycling investment package announced by the mayor on Monday.

Under the plan, part of a series of environmental measures due in coming days, 6,000 bicycles will be available for hire from ranks every 600 feet throughout the city centre.

London, which accounts for seven percent of the country's climate changing carbon emissions and is at the forefront of efforts by major cities around the world to combat global warming, plans to cut carbon emissions by 60 percent by 2025.

The Paris bike scheme lets riders with an electronic card take a bike from one rank and return it at another rank anywhere in the city. It has proven popular, transforming traffic in the French capital since it came into operation last July.

Mayor Ken Livingstone's initial announcement did not give details of how much the cycles would cost to rent in London or how Londoners would pay for them.

"We will spend 500 million pounds over the next decade on cycling -- the biggest investment in cycling in London's history, which means that thousands more Londoners can cycle in confidence on routes that take them quickly and safely to where they want to go," Livingstone said in a statement.

"Around 20 percent of the carbon emissions savings we've calculated we can make from transport by 2025 will come from changing the way we travel," he added.

Other aspects of the scheme include new cycle paths and exclusive cycle zones and more bike parking facilities at underground stations across the capital.

Livingstone, facing a tough mayoral election in May with the environment as one of the major campaign issues, said he wanted five percent or 1.7 million of all daily trips in London to be by bike by 2025.

On Tuesday Livingstone is expected to announce his decision to go ahead from October with a plan to charge drivers of gas-guzzling Sport Utility Vehicles 25 pounds a day to drive in central London's congestion charge zone. Ordinary cars pay eight pounds a day to drive in the zone.

A low emission zone targeting heavy lorries came into force on Monday in the 600 square mile area inside the M25 ring road circling the sprawling city.

Added to that, Livingstone was also due to announce a comprehensive plan to fit new filters and equipment to all municipal buildings in the city to cut their carbon emissions.

China's freak snow means wildfires to come

China's freak snow means wildfires to come

The freakish snowstorms which have been sweeping across China since early January have damaged one tenth of the nation's forests. The State Forestry Administration reports that 17.3 million hectares of forests have been affected - an area larger than England.

Trees suffer from the weight of heavy snowfall, which can bend or break branches, and even kill the whole tree, depending on the species and their size.

Research has shown that death by snow and ice can have all sorts of implications for forests, from boosting regrowth to boosting biodiversity (both a result of more light and "vacant" ecological niches).

On the grimmer side of things, they also generate dead plant debris excellent fodder for summertime forest fires. Already, a SFA spokesman has warned that trees killed by the cold weather could lead to fire disasters later this year.

This year's snowstorms have been the worst in 5 decades. The total cost of the damage has yet to be determined. On 31 January, the SFA announced that the storms would cost 16.2 billion yuan (about $2.5 billion) in damaged forests, but the storms have been sustained since then, and more are predicted for this week.

Meteorologists have blamed the weather on La Nina, which warms up Pacific waters off the coasts of Asia. As a result, warm moist air comes in over the land and mixes with cold air from the north, resulting in heavy snow.
