Is it greener to shop online?
Shopping has become a cloak-and-dagger affair. Conspicuous consumption does not look good during a recession, which explains why so many of us are embracing e-commerce. Online shopping on these shores is projected to grow from sales of £8.9bn to around £21.3bn by the end of 2011.
Often people proclaim they've embraced e-commerce because it's "green". This is understandable. If many shopping bags in a recession looks bad, bricks and mortar retail - huge out-of-town shopping centres, retail emporia that insist on leaving their doors open even in winter and grocery stores full of the most inefficient freezers - look terrible during an ecological emergency.

Jumbo flying squid have invaded the shallow waters off San Diego, California, spooking scuba divers and beachgoers after washing up dead on the beaches.
The carnivorous cephalopods, which weigh up to 45kg (100lb), came up from the depths last week, with swarms of them roughing up unsuspecting divers. Some reported tentacles enveloping their masks and yanking at their cameras and gear.

Fox attacks on endangered penguins have led Australia's wildlife authorities to post snipers at night to protect the birds.
A colony of about 120 little penguins (Eudyptula minor), also known as fairy penguins, at Quarantine beach in Sydney has recently lost about nine of its number to attacks. On Sunday night, the two snipers took their first watch but were unable to shoot the animals responsible.

Seldom has a book been more cleanly murdered by scientists than Ian Plimer's Ian Plimer's Heaven and Earth, which purports to show that manmade climate change is nonsense. Since its publication in Australia it has been ridiculed for a hilarious series of schoolboy errors, and its fudging and manipulation of the data. Here is what the reviews have said.
Professor David Karoly, University of Melbourne's School of Earth Sciences:

When Fritz Müller and Erwin Schneider battled ice storms, altitude sickness and snow blindness in the 1950s to map, measure and photograph the Imja glacier in the Himalayas, they could never have foreseen that the gigantic tongue of millennia-old glacial ice would be reduced to a lake within 50 years.
But half a century later, American mountain geographer Alton Byers returned to the precise locations of the original pictures and replicated 40 panoramas taken by explorers Müller and Schneider. Placed together, the juxtaposed images are not only visually stunning but also of significant scientific value.

High rates of obesity in richer countries cause up to 1bn extra tonnes of greenhouse gas emissions every year, compared with countries with leaner populations, according to a study that assesses the additional food and fuel requirements of the overweight. The finding is particularly worrying, scientists say, because obesity is on the rise in many rich nations.
"Population fatness has an environmental impact," said Phil Edwards, from the London School of Hygiene and Tropical Medicine. "We're all being told to stay fit and keep our weight down because it's good for our health. The important thing is that staying slim is good for your health and for the health of the planet."

Almost nine out of 10 climate scientists do not believe political efforts to restrict global warming to 2C will succeed, a Guardian poll reveals today. An average rise of 4-5C by the end of this century is more likely, they say, given soaring carbon emissions and political constraints.
Such a change would disrupt food and water supplies, exterminate thousands of species of plants and animals and trigger massive sea level rises that would swamp the homes of hundreds of millions of people.

• Climate change threatens 50 years of progress in global health, study says
Britain and other European governments have been accused of underestimating the health risks from shipping pollution following research which shows that one giant container ship can emit almost the same amount of cancer and asthma-causing chemicals as 50m cars.
Confidential data from maritime industry insiders based on engine size and the quality of fuel typically used by ships and cars shows that just 15 of the world's biggest ships may now emit as much pollution as all the world's 760m cars. Low-grade ship bunker fuel (or fuel oil) has up to 2,000 times the sulphur content of diesel fuel used in US and European automobiles.

Fishermen in the Philippines accidentally caught a megamouth shark, one of the rarest fish in the world and later ate it after it had been identified. Only 40 other sightings of the shark have ever been recorded, according to the World Wildlife Fund.
The 500kg, four metre megamouth (Megachasma pelagios) died while struggling in the fishermen's net on 30 March off Burias island in the central Philippines. It was taken to nearby Donsol in Sorsogon province, said Gregg Yan, a spokesman for WWF-Philippines.

Wendy Richard's funeral was notable not just for the number of EastEnders stars among the mourners but the fact that her coffin was woven from bamboo.
Richard's family chose an eco-friendly coffin because they did not want a tree to be chopped down, according to its manufacturer, Ecoffins. The company stresses its environmental credentials: the bamboo is harvested from sustainable, licensed plantations and is not the species eaten by pandas; its Chinese factory is certified Fairtrade. With smart packing, they claim the shipping of one coffin from China uses the same amount of fuel as driving a car 4.63 miles.

One fine day in 1994, two policemen struggled up to the protest camp on Solsbury Hill, near Bath, and asked to be taken to the leaders. "You want to talk to Aqua and Sulis," someone told them. "They're up the top. You'll recognise them 'cos they're both black." The officers sweated up to the top of the hill and told the people there who they wanted to talk to. Everyone stared at them. "Aqua and Sulis? You sure about that?" they asked. "Definitely," the policemen replied. And so they were taken to meet the two black piglets that were kept as pets at the camp.
No one returned from Solsbury Hill unchanged. The battle against Batheaston bypass was a turning point in the fight against the government's road building programme, and in the lives of many of the people who became involved in it.

Despite petitions calling for his sacking and even fellow unionists accusing him of turning Northern Ireland into a laughing stock, the Democratic Unionist party is sticking by climate change sceptic Sammy Wilson, who is the province's environment minister.
All the major parties in the Northern Ireland assembly have now said Wilson is unfit to hold the office, after he used his powers this week to ban government television adverts from the province's airwaves. Wilson said the Act On CO2 ads were insidious green "propaganda".

Read the full interview with James Hansen here
Barack Obama has only four years to save the world. That is the stark assessment of Nasa scientist and leading climate expert Jim Hansen who last week warned only urgent action by the new president could halt the devastating climate change that now threatens Earth. Crucially, that action will have to be taken within Obama's first administration, he added.

It is a cautionary tale of recklessness, good intentions and the ecological mayhem that can result when people interfere with the delicate balance of Mother Nature: scientists today catalogued the unfortunate series of biological events caused by human meddling and alien species that has devastated the once pristine sub-Antarctic Macquarie Island.
Lessons must be learnt on all sides, the scientists say, because well-intentioned attempts by conservation experts to fix the island have so far made the situation worse. Life across almost half the island, a World Heritage site, has been affected, and experts are now weighing up a £11m rescue plan.

There will surely come a day when Dubai runs the world's reserves of hyperbole dry. But in the meantime, we continue to draw a sharp intake of breath each time a new construction project is announced. We have had ski domes built in the desert, seen vast artificial islands rise from the sea and watched several structures vying for the title of world's tallest building. Dubai represents the will, vision and ambition of our species. Yet many believe it shines an unflattering light on our tendency for folly and hubris, too.
This week, it was reported that the Palazzo Versace hotel - the Emirate's latest offering for those still in the market for exorbitant luxury - will boast, when completed in 2010, a refrigerated 820sq metre swimming pool and a beach with artificially cooled sand to protect its guests from the excesses of a climate that can see summer temperatures exceeding 50C. Wind machines will even be on hand to provide a gentle breeze.

Silkworms: an environmentally friendly delicacy?
According to legend, 5,000 years ago Chinese Empress Xi Ling-Shi discovered silk when a silkworm cocoon fell into her hot cup of tea. She unraveled the strange cocoon and, wrapping the thread around her finger, soon realized what an exquisite cloth it would make. Thus the history of one of the world's most coveted fabrics began.
If this is true, the silkworm that haplessly fell into the empress' cup on that fateful day met a fate very similar to that of modern day silkworms. When they exit the cocoon after metamorphosis, silkmoths must bore a hole through the cocoon wall, which ruins the precious thread. Therefore, silk factories drop the cocoons in hot water before the moth can leave. This unravels the thread well, but it boils down to bad news for the silkworms.

A tree fungus could provide green fuel that can be pumped directly into tanks, scientists say. The organism, found in the Patagonian rainforest, naturally produces a mixture of chemicals that is remarkably similar to diesel.
"This is the only organism that has ever been shown to produce such an important combination of fuel substances," said Gary Strobel, a plant scientist from Montana State University who led the work. "We were totally surprised to learn that it was making a plethora of hydrocarbons."
