Greenland ice sheet faces 'tipping point in 10 years'
The entire ice mass of Greenland will disappear from the world map if temperatures rise by as little as 2C, with severe consequences for the rest of the world, a panel of scientists told Congress today.
Greenland shed its largest chunk of ice in nearly half a century last week, and faces an even grimmer future, according to Richard Alley, a geosciences professor at Pennsylvania State University

Much has been written about a war between cyclists and drivers, as if the two groups were such polar opposites that they could never cross in a Venn diagram. But according to new research, people who cycle the most are likely to own at least two cars.
Regular cyclists – those who cycle at least once a week – are also disproportionately likely to read broadsheet newspapers, be well educated, have a household income of at least £50,000 per year and shop at Waitrose, claims the latest Mintel report, Bicycles in the UK 2010. In addition, they are twice as likely to be men as women.

Whatever happened to the humblebee, the old name for the bumblebee, asked Angus Doulton of Oxfordshire in a letter to the Guardian last week.
When Darwin, or indeed any of his contemporaries, wrote of the animated bundles of fluff, he would have called them humblebees. But they weren't humble in the sense of lowly beings doing the drudge work of nectar and pollen collecting; rather they would have been celebrated for the powerful evolutionary interaction with the flowers they had visited for millions of years. Darwin would have called them humblebees because, as they fly, they hum. Simple.

Vital warning systems on the Deepwater Horizon oil rig were switched off at the time of the explosion in order to spare workers being woken by false alarms, a federal investigation has heard.
The revelation that alarm systems on the rig at the centre of the disaster were disabled – and that key safety mechanisms had also consciously been switched off – came in testimony by a chief technician working for Transocean, the drilling company that owned the rig.

• Queen's executioner beetle wins species naming competition
• See the full list of winners
It's the most successful exercise in crowd-sourcing I've ever seen. We asked our readers to solve a problem, and they've done far more than that: they have created something beautiful.
The problem is this: it is hard to persuade people to care about something they can't pronounce. English species are disappearing at the rate of two a year. But many are vanishing unnoticed and unmourned by almost everyone, partly because we have no cultural connection to them. Scientific names, which are given in Latin or ancient Greek, are essential to proper classification, but to most people they are cold, incomprehensible and offputting.

UK consumers get through millions of teabags every day to make their favourite drink yet the vast majority are not fully biodegradable, a consumer organisation warns today.
A report published today by Which? Gardening reveals that teabags produced by top tea manufacturers such as Tetley, PG Tips, Twinnings, Clipper and Typhoo are only between 70-80% biodegradable. As a result, gardeners are finding the net part of teabags - caused by the inclusion of heat-resistant polypropylene - left on their compost heaps.

• More carbon footprints: nuclear war, a cappuccino, more
• Understand more about carbon footprints
Bananas are a great food for anyone who cares about their carbon footprint. For just 80g of CO2e you get a whole lot of nutrition: 140 calories as well as stacks of vitamin C, vitamin B6, potassium and dietary fibre. All in all, a fantastic component of a low-carbon diet.

Flop flop flop. The sound of a bird's wings batting futilely against the gloopy blanket of black oil echoes across the quarry. Then there is silence. A pigeon has crashed into this dark pool, 100 metres from the turquoise sea on the west coast of Guernsey. It sinks within seconds, resurfaces for a final flap, then joins the other small carcasses lying face down in the swirls of black slime. Since 1967, this deadly, oil-filled crater on the Chouet headland has acquired a new name: Torrey Canyon quarry.
On the morning of Saturday 18 March 1967, the Torrey Canyon ran aground on Pollard's Rock between Land's End and the Isles of Scilly. Over the following days, every drop of the 119,328 tonnes of crude oil borne by this 300m-long supertanker seeped into the Atlantic. Thousands of tonnes despoiled the beaches of Cornwall – and thousands more were propelled by winds and currents across the channel towards France.

Greta Scacchi is urging fellow stars to step up and campaign for causes they believe in, regardless of any criticism they may receive. The actress, who last year promoted End of the Line, an influential documentary about over-fishing, by posing nude with a cod, says that she is delighted to have found a useful public role.
"It suits me in my older age. I am able to use muscles now that I was not able to use before, and it is very heartening to find I am not just asked what I wash my face with these days," she said.

It's advertised as the "pure essence of masculinity", a fragrance with a musky, sensual aroma that, by implication, women are bound to find irresistible. But what's not mentioned in the marketing is that Calvin Klein's Obsession for Men has also proved a hit with jaguars in the Guatemalan jungle.
Scientists are using the cologne to lure the elusive big cats to hidden cameras in the Maya biosphere reserve, a protected tropical rainforest spanning 8,100 sq miles, to help them record, monitor and protect the animals.

A global shift towards a vegan diet is vital to save the world from hunger, fuel poverty and the worst impacts of climate change, a UN report said today.
As the global population surges towards a predicted 9.1 billion people by 2050, western tastes for diets rich in meat and dairy products are unsustainable, says the report from United Nations Environment Programme’s (UNEP) international panel of sustainable resource management.

• Sustainable fishing move could help your cat reduce its eco pawprint
• Britain's problem with pets: they're bad for the planet
This week is National Vegetarian Week, the annual celebration of all things vegetarian. Taking the veggie option has never been easier for people, but what about vegetarian pets?
Jonathan Safran Foer's recent polemic Eating Animals makes much of the contrast between our love for our pets and our complacency at the horrors of the factory farm and the abattoir. That contradiction is no more keenly felt than by the vegetarian dog or cat owner, supporting the meat industry they abhor every time they stock up on pet food.

• Deepwater Horizon oil spill reaches the coast
These things Stephen Davis cannot banish from his memory from that night of chaos aboard the Deepwater Horizon: the sensation of being flung into a wall by a powerful explosion, the desperate, muddy scramble on a deck lit only by the reflections from a huge pillar of flame; the look in men's eyes before they jumped 18 metres (60ft) into the water.
"You could taste the fumes, that godawful taste in your mouth," he said. "It was hard to breathe. The oxygen was being sucked out of the living quarters.

As I cycle home I'm conscious of an ominous rumble behind me. A quick glance over my left shoulder confirms my worst fears: a looming heavy goods vehicle is blocking out the sun.
I don't fancy taking it on with only my helmet and luminous vest as protection, so I veer to closer to the kerb so it can overtake. We meet again at traffic lights, and again I shrink towards the edge of the road.

Campaigners have criticised plans for a sea trial of cloud-whitening technology, funded by Microsoft founder Bill Gates.
A US-based research body, Silver Lining, which has received $300,000 from Mr Gates, is developing machines to convert seawater into microscopic particles to be sprayed into clouds. Scientists believe this will increase the whiteness, or albedo, of clouds and increase their ability to reflect more sunlight back into space, reducing global warming.

• Should I ... use paper towels or a hand-dryer?
• American taste for soft toilet roll 'worse than driving Hummers'
"Hand-to-hand" combat has erupted between two of the companies responsible for drying the digits of the nation.
Dyson, the makers of the Airblade dryer, has accused Kimberly Clark of landing a low blow, by saying the air jets its machine uses increases the bacteria on hands. Dyson says the US paper towel corporation has used "biased and misleading" research to support the claim, and to state that paper towels are just as environmentally friendly as the air dryer.

It started last year with two men in a pub. It spiraled from there, and gathered in thousands of people from across the world who shared its vision. It is still expanding; so much so that the two men now have rather less time to spend in the pub, because much of their day is spent just trying to keep up with a minor global movement which they have accidentally brought into being.
This is the story of the Dark Mountain Project, a new cultural movement for an age of global disruption, of which I was one of the co-founders less than a year ago. It seems much longer; a lot has happened in a year. We seem to have touched a nerve. This is all the more interesting to me because this project began life as a response to a sense of disillusion with what environmentalism has become.

Along with the ash and lava, there have been many interesting asides tossed into the air for our consideration by the Eyjafjallajokull volcano. We have noticed just how reliant our globalised systems are on air travel. We have been reminded of nature's brute force and primordial beauty. And we have been intrigued by what a wonderfully complex language Icelandic appears to be – to Anglo-Saxon ears, at least.
But one opportunity the volcano has gifted us in particular is the chance to put to bed once and for all that barrel-aged climate sceptic canard which maintains that volcanoes emit far more carbon dioxide than anthropogenic sources. It's always been a favourite, but has been pushed even further up the charts of popularity in recent months by the repeated claims of Ian Plimer, the Australian mining geologist who wrote the climate sceptic bible Heaven and Earth last year.

A rare image of a clouded leopard on the ground has been captured by a researcher in Indonesia who was trying to photograph slightly less unusual sun bears.
Wai-Ming Wong is working on a doctorate at the University of Kent on how the bears ‑ which are regarded as less critically vulnerable than the leopards, but have received far less attention academically ‑ are surviving in human-dominated landscapes.

• Ghost orchid comes back from extinction
For the first time since the dinosaurs disappeared, humans are driving animals and plants to extinction faster than new species can evolve, one of the world's experts on biodiversity has warned.
Conservation experts have already signalled that the world is in the grip of the "sixth great extinction" of species, driven by the destruction of natural habitats, hunting, the spread of alien predators and disease, and climate change.
