Ottawa removing North Pacific humpback whales from list of ‘threatened’ species so it can build more oil pipelines
"The decision removes a major legal hurdle that the environmental group Ecojustice said stood in the way of the $7.9-billion Northern Gateway pipeline project that would bring 550,000 barrels of diluted bitumen crude from Alberta to Kitimat." - Nicķ from Bookmarklet

Alan Titchmarsh was sent a personal apology from David Cameron after a Cabinet minister called him a “complete muppet”. Mr Paterson’s comments came after Titchmarsh claimed that the horticultural industry had warned of ash dieback years before it was first discovered in Britain in February 2012, and that official advice to wash boots after visiting woodland was like “sticking a plaster on a broken leg”. - Halil from Bookmarklet

"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

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

"By the end of this year, if a Chinese entrepreneur gets his way, digging will begin on a waterway that would stretch roughly 180 miles across Nicaragua to unite the Atlantic and Pacific oceans. Giant container ships capable of carrying consumer electronics by the millions (or T-shirts by the billions) could begin making the passage by 2019, according to the most optimistic projections. A canal across Nicaragua has been a dream of kings and entrepreneurs for centuries. Like the ill-fated schemes that preceded it, the newest incarnation has its share of interesting characters, rumors, and controversy. As word of the plan spreads, scientists and other experts are asking questions and finding potentially serious flaws.

"The Tōhoku earthquake and tsunami may have struck three years ago, but radioactive water from Japan's beleaguered Fukushima nuclear power plant is now being detected near Canada's West Coast. Scientists will be monitoring North American shores for the next two months, but projections point to good news. Minute traces of radionuclides were recently detected off the coast of British Columbia. The contaminated water has yet to reach Washington, California, or Hawaii. According to researchers who met yesterday at the annual American Geophysical Union's Ocean Sciences Meeting in Honolulu, radiation levels will increase as contaminants slowly swell eastwards." - Bluesun 2600 from Bookmarklet

The next breakthrough for a bike-friendly world: Protected intersections! (video) : TreeHugger
"Protected bike lanes are great, and thankfully they are becoming more common. But when you reach an intersection on a bike, you usually have to leave the protected zone and fend for yourself, hoping that motorists see you and that everybody follows the sometimes confusing traffic signals and lights. But it doesn't have to be that way (we don't have to live like animals!). Protected intersections are the answer we've been looking for. Urban planner Nick Falbo has been studying Dutch intersections and has adapted the solutions used there to keep cyclists safe to the US urban environment. He made this really, really great video to explain how it works. Really, you have to watch this. Production quality is impressive and everything is well explained. I hope that it spreads like wildfire among urban planners" - Bluesun 2600 from Bookmarklet

How to reverse desertification. With rocks. : TreeHugger
"From a fanciful Sahara forest concept to the planting of trees to stop the encroachment of desert, we've seen plenty of ideas for turning arid, hostile environments into productive ecosystems. The work of permaculture expert Geoff Lawton is often quoted in this regard. From exploring existing, 2000-year-old food forests to greening the deserts of Jordan, he's been talking about and teaching dry land permaculture concepts for many years. His latest video is another offering on this topic, looking at the use of "gabions" or simple rock walls as a means to slow down the flow of flood waters, encourage the build up of silt and organic matter, and begin the process of natural regeneration." - Bluesun 2600 from Bookmarklet

BBC News - Wavier jet stream 'may drive weather shift'
"New research suggests that the main system that helps determine the weather over Northern Europe and North America may be changing. The study shows that the so-called jet stream has increasingly taken a longer, meandering path. This has resulted in weather remaining the same for more prolonged periods. The work was presented at the annual meeting of the American Association for the Advancement of Science (AAAS) in Chicago. Prof Francis was taking part in a session on Arctic change involving Mark Serreze, the director of the US National Snow and Ice Data Center in Colorado. He said the idea that changes in the polar north could influence the weather in middle latitudes - so-called "Santa's revenge" - was a new and lively area of research and somewhat controversial, with arguments for and against." - Big Joe Silence from Bookmarklet
"Fundamentally, the strong warming that might drive this is tied in with the loss of sea-ice cover that we're seeing, because the sea-ice cover acts as this lid that separates the ocean from a colder atmosphere," Dr Serreze explained. "If we remove that lid, we pump all this heat up into the atmosphere. That is a good part of the signal of warming that we're now seeing, and that could be driving some of these changes." - Big Joe Silence

Oregon Prepares to Launch the West Coast's First Offshore Wind Farm | Inhabitat - Sustainable Design Innovation, Eco Architecture, Green Building
"The Pacific Northwest state of Oregon is already home to America’s second largest land-based wind farm — the 845 megawatt (MW) Shepherds Flat Wind Farm. Now the state has taken a big step closer to hosting the west coast’s first offshore wind farm. The Bureau of Ocean Energy Management (BOEM) just approved plans for Seattle-based Principle Power develop five floating turbines off Coos Bay. The 30 MW pilot project will be located in about 1,400 feet of water roughly 15 miles off the Oregon coast. The reason for using floating turbine technology in deep water as opposed to wind turbines anchored to the seabed in shallow water has to do with the west coast’s narrow continental shelf. This pioneering project would demonstrate floating wind turbine technology capable of tapping the rich wind energy resources in deep waters offshore Oregon. As we look to broaden our nation’s energy portfolio, the innovative technology and its future application holds great promise along the West Coast and... more... - Bluesun 2600 from Bookmarklet

Hungry polar bears are devastating seabird populations by eating eggs
While these bears may have occasionally eaten bird eggs in the past, the researchers believe they are now targeting the nesting colonies. In fact, their data shows that polar bear incursions into seabird nesting colonies have increased more than seven fold since the 1980s, and bears show up more frequently as the sea ice season shortens. Iverson said warming temperatures in the Arctic haven't directly affected seabirds, but the study suggests it may still have a negative impact in the end. "I think that it shows that the effects of climate change are much more far reaching than we anticipate," he said. - Halil

Study: Replacing BPA in food products could save billions in health costs – The Pump Handle
"In a first-of-its-kind study, a researcher has estimated that the health-related economic savings of removing bisphenol A from our food supply is a whopping $1.74 billion annually. And that’s a conservative estimate. “This study is a case in point of the economic burden borne by society due to the failure to regulate environmental chemicals in a proactive way,” study author Leonardo Trasande told me. With evidence mounting that bisphenol A (BPA) exposure is a serious health risk, Trasande, an associate professor in pediatrics, environmental medicine and health policy at New York University, wanted to examine the economic trade-offs of replacing BPA with a safer alternative. BPA, a synthetic compound used in plastics and found in the lining of food and beverage containers, has been identified as an endocrine disruptor and linked to cancer, asthma, fertility outcomes, adverse neurobehavioral development, obesity promotion and cardiovascular risks.
