Why no one should freak out about the giant crack that opened in the Mexico desert - The Washington Post
"On the issue of the huge gaping chasm that opened in the Mexican desert earlier this month, scientists have assured us this does not herald the end of days. The chair of the geology department at the University of Sonora, in the northern Mexican state where this “topographic accident” emerged, said that the fissure was likely caused by sucking out groundwater for irrigation to the point the surface collapsed." - imabonehead from Bookmarklet

90 percent of Earth's species are overlooked in conservation
UK Professor Tom Curtis : I make no apologies for putting micro-organisms on a pedestal above all other living things, for if the last blue whale choked to death on the last panda, it would be disastrous but not the end of the world. But if we accidentally poisoned the last two species of ammonia-oxidisers, that would be another matter. It could be happening now and we wouldn't even know - Halil from Bookmarklet

A new assessment from Europe's CryoSat spacecraft shows Greenland to be losing about 375 cu km of ice each year. Added to the discharges coming from Antarctica, it means Earth's two big ice sheets are now dumping roughly 500 cu km of ice in the oceans annually. "The contribution of both ice sheets together to sea level rise has doubled since 2009," said Angelika Humbert from Germany's Alfred Wegener Institute. "To us, that's an incredible number," she told BBC News. - Halil from Bookmarklet

Stacked solar cells could make solar power cheaper than natural gas : TreeHugger
" Researchers everywhere are working on developing better solar cells: ones with higher power output, ones that can adhere to any surface, ones that cool or clean themselves, etc. Upping the efficiency of solar cells is probably the biggest focus. Right now, commercial solar cells can convert about 15 to 25 percent of the energy from sunlight into electricity. The holy grail for years has been reaching a 50 percent conversion efficiency. In labs, researchers have been able to hit efficiencies as high as 44.7 percent, but the start-up Semprius says they have a technique for stacking solar cells that would lead to that magic 50 percent number, and not just in a lab. Not only that, but because the solar cells are small and cheap to manufacture, the company believes that this technology could also lead to solar power cheaper than natural gas. MIT Technology Review says, "Semprius has come up with three key innovations: a cheap, fast way to stack cells, a proprietary way to electrically... more... - Bluesun 2600 from Bookmarklet

Changing farming practices could cut the intensity of heat waves | Ars Technica
"As the Earth's climate continues to warm, the elevated temperatures can put a strain on agriculture. Although an increase in the average temperature can harm crops, it's the details obscured by that average that can cause the biggest problems: more—and more extended—periods of extreme temperatures often harm crops far more than raising the typical temperature a fraction of a degree." - imabonehead from Bookmarklet
"Fortunately, as a team of Swiss and French researchers have determined, the opposite may also be true. They've identified a simple agricultural practice that does little to alter the average temperature of farming areas. But it does have a strong effect on extreme temperatures, lowering them by nearly 2°C. That should be enough to keep existing crops viable for longer in the face of future climate change." - imabonehead
"The technique in question is called "no-till farming," and it simply involves leaving the debris from previous crops on the surface of the fields rather than plowing the fields and exposing the soil underneath. Observations of test agricultural fields indicate that no-till practices have several effects. To begin with, the debris tends to retain moisture, which limits evaporation;... more... - imabonehead

This tiny portable wind turbine fits in your bag and charges your gadgets : TreeHugger
"In our current gadget-centric culture, one limiting factor for mobile devices is the capacity of the batteries that power them, and while we haven't seen any massive improvements in battery technology (yet) which would allow us to go for days between charges, mobile solar chargers and battery backup systems seem to be the only solutions (well, other than to actually stop using them so much). Wind turbines are a viable clean energy solution, but most of the innovations in wind energy tend to be on the large scale, and since those devices aren't exactly portable, they don't lend themselves to mobile device charging. But one forthcoming invention may allow us to harness the power of the wind with a micro turbine, in order to charge our smartphones and tablets and other USB devices. Although the efficacy of small wind turbines, especially vertical axis wind turbines (VAWT), is often debated, and the designs dismissed as not being worth their cost or manufacturing resources, but that... more... - Bluesun 2600 from Bookmarklet

Will We Still Have Fruit if Bees Die Off? | Science Blogs | WIRED
"A photo has been circulating for a while that suggests our grocery stores will look like this in a world without bees. Is that true? Will our food choices be radically limited, come the future Beepocalypse? We already know what raising fruit without honey bees looks like. In a remote area in China, humans pollinate 100% of fruit trees by hand. Armed with pollen-loaded paintbrushes and cigarette filters, people swarm around pear and apple trees in spring. The reason why they hand pollinate is not what you think, though. Honey bees are still present in these areas of hand pollination, and many fruit growers also keep bees for honey. Hand pollination in China has as much to do with economics and fruit biology as it does with bees. In the early 1990s, farmers of marginal lands in the Hindu Kush Himalayan region–an area spanning parts of Nepal, China, Pakistan, and India–realized that apples could be a major cash crop. Their land was mountainous and hard to farm, so tree fruits were... more... - Bluesun 2600 from Bookmarklet

Spraying Toxic Coal Ash Is A Cheap And Popular Way To De-Ice Roads | ThinkProgress
"The months of relentless winter weather that have pummeled much of the nation have forced many communities to get creative when it comes to de-icing roads. With salt for roads in short supply, everything from beet juice to cheese brine is being used to help drivers stay in control on slippery streets — including coal ash. That’s right, for years, cities and towns in Pennsylvania, Ohio, New Mexico, Missouri, Oklahoma, Virginia, Illinois, Iowa, and Colorado have sprayed the toxic waste on roads to combat winter ice and snow. Municipalities often get it for free from power plants who are eager to dispose of it somehow and it never seems to be in short supply. Coal ash, the residue left over from burning coal to generate electricity, contains some very dangerous substances including arsenic, lead, mercury chromium, and cadmium. When coal ash washes from a road into a ditch or storm sewer it can leach toxic compounds into the water and soil. According to the American Coal Ash Association,... more... - Bluesun 2600 from Bookmarklet

BBC News - Mysterious new man-made gases pose threat to ozone layer
Show all
"Scientists have identified four new man-made gases that are contributing to the depletion of the ozone layer. Two of the gases are accumulating at a rate that is causing concern among researchers. Worries over the growing ozone hole have seen the production of chlorofluorocarbon (CFC) gases restricted since the mid 1980s. But the precise origin of these new, similar substances remains a mystery, say scientists. Lying in the atmosphere, between 15 and 30km above the surface of the Earth, the ozone layer plays a critical role in blocking harmful UV rays, which cause cancers in humans and reproductive problems in animals. Scientists from the British Antarctic Survey were the first to discover a huge "hole" in the ozone over Antarctica in 1985." - Big Joe Silence from Bookmarklet
"The evidence quickly pointed to CFC gases, which were invented in the 1920s, and were widely used in refrigeration and as aerosol propellants in products like hairsprays and deodorants. Remarkably, global action was rapidly agreed to tackle CFCs and the Montreal Protocol to limit these substances came into being in 1987." - Big Joe Silence
"A total global ban on production came into force in 2010. Now, researchers from the University of East Anglia have discovered evidence of four new gases that can destroy ozone and are getting into the atmosphere from as yet unidentified sources." - Big Joe Silence
